ABSTRACT: OBJECTIVE: To evaluate the relationship between preterm premature rupture of membranes (PPROM) and cognitive impairment in 5-year-old children born very preterm. STUDY DESIGN: The Etude Epidémiologique sur les Petits Ages Gestationnels Study is a population-based cohort of children followed up from birth to age 5 years recruited in 9 French regions in 1997. We analyzed data from singletons born between 24 and 32 weeks gestation categorized into 4 groups according to etiology of prematurity: infants born after PPROM, after idiopathic preterm labor, in a vascular context (Vasc), and to women with other complications (Other). Cognitive development at age 5 years was assessed using the Mental Processing Composite score of the Kaufman-Assessment Battery for Children. RESULTS: Among the 1051 children followed up to age 5 years, the mean Mental Processing Composite score was 93.6 ± 19.7, and 13.3% of the children (140 of 1051) had cognitive impairment. After adjustment for potential confounders, the risk of cognitive impairment among infants in the PPROM group was not significantly different than that in the idiopathic preterm labor group (OR, 1.09; 95% CI, 0.62-1.92) and the Other group (OR, 1.36; 95% CI, 0.75-2.47), but was lower than that in the Vasc group (OR, 1.86; 95% CI, 1.16-2.97). In the PPROM group, the risk of cognitive impairment was greater when the latency period (ie, time from rupture to delivery) was <3 days (OR, 2.32; 95% CI, 1.07-5.02). CONCLUSION: Preterm infants born after PPROM are not at increased risk for cognitive impairment in childhood, but the time between PPROM and birth may influence that risk.

ABSTRACT: The present paper aims to analyze trends over time in prevalence of cerebral palsy of post-neonatal origin, to investigate whether changes are similar according to severity and to describe the disability profile by etiology. Post-neonatal cases, birth years 1976 to 1998, were identified from the Surveillance of Cerebral Palsy in Europe collaboration (19 population-based registries). A recognized causal event occurring between 28 days and 24 months of age was considered to define the cases. Trends in prevalence were explored using graphical methods (Lowess and Cusum control chart) and modeled with negative binomial regressions. Over the study period, 404 cases were identified as post-neonatal cases (5.5% of the total). Mean prevalence rate was 1.20 per 10,000 live births (95% CI [1.08-1.31]). A significant downward trend was observed (p=0.001), with an accentuated decrease in the 1990s. The prevalence of severe cases which account for around one third of the total also significantly decreased over time (p<0.001). In 46% of cases, an infectious aetiology was reported; the corresponding prevalence significantly decreased since 1989. No significant decrease was observed for the rate of cases due to a vascular episode or of traumatic origin. Our results emphasize the need of large population-based surveillance systems to reliably monitor trends in prevalence in rare subgroups of children like those with acquired cerebral palsy. The decrease of the overall prevalence as well as those of the most severe cases may be partly due to public health actions targeted to prevent such events.

ABSTRACT: To investigate the association of motor and cognitive/learning deficiencies and overall disabilities in very preterm (VPT) children and their relations to gestational age (GA) and brain lesions.
EPIPAGE is a longitudinal population-based cohort study of children born before 33 weeks' gestation (WG) in 9 French regions in 1997-1998. Cumulating data from all follow up stages, neurodevelopmental outcomes were available for 90% of the 2480 VPT survivors at 8 years. Main outcomes were association of motor and cognitive deficiencies and existence of at least one deficiency (motor, cognitive, behavioral/psychiatric, epileptic, visual, and/or hearing deficiencies) in three GA groups (24-26, 27-28, and 29-32WG) and four groups of brain lesions (none, minor, moderate, or severe).
VPT had high rates of motor (14%) and cognitive (31%) deficiencies. Only 6% had an isolated motor deficiency, 23% an isolated cognitive one and 8% both types. This rate reached 20% among extremely preterm. Psychiatric disorders and epilepsy were observed in 6% and 2% of children, respectively. The risks of at least one severe or moderate deficiency were 11 and 29%. These risks increased as GA decreased; only 36% of children born extremely preterm had no reported deficiency. Among children with major white matter injury (WMI), deficiency rates reached 71% at 24-26WG, 88% at 27-28WG, and 80% at 29-32WG; more than 40% had associated motor and cognitive deficiencies. By contrast, isolated cognitive deficiency was the most frequent problem among children without major lesions.
In VPT, the lower the GA, the higher the neurodisability rate. Cerebral palsy is common. Impaired cognitive development is more frequent. Its occurrence in case without WMI or early motor disorders makes long-term follow up necessary. The strong association between motor impairments, when they exist, and later cognitive dysfunction supports the hypothesis of a common origin of these difficulties.

ABSTRACT: The principle of inclusive education has been increasingly recognised over recent decades and most countries officially support schooling of children with disabilities in mainstream settings. The SPARCLE study offers the opportunity to report on the schooling practices for children with cerebral palsy according to the nature and severity of their impairments and the schooling policy in European regions. The aim of this paper is to describe the type of schooling of children with cerebral palsy in various European regions after controlling for relevant individual factors. Children aged 8-12 years with cerebral palsy from 9 European regions and their families were interviewed. Our findings support the hypothesis that between-region variations in the type of schooling are still significant after adjustment for individual factors; and that motor function and intellectual ability have different effects on inclusion in mainstream school, depending on the region.

ABSTRACT: BACKGROUND: To compare the strength of the association between peer victimization at school and subjective health according to the disability or chronic illness (D/CI) status of students across countries. METHODS: This study used data from 55 030 students aged 11, 13 and 15 years from 11 countries participating in the 2005-06 Health Behaviour in School-aged Children survey. Self-completed questionnaires were administered in classrooms. Multivariate models of logistic regression (controlled for confounding factors and countries) were used to investigate differences in the association between peer victimization and poor subjective health according to the D/CI status. RESULTS: Overall, 13.5% of the students reported having been bullied at least two or three times a month. The percentage of victims was significantly higher among those reporting D/CI than among others in all countries studied. Victims of bullying were more likely to report poor self-rated health, low life satisfaction and multiple health complaints. However, there were no differences in the associations between peer victimization and subjective health indicators according to the D/CI status. CONCLUSIONS: In all countries studied, students reporting D/CI were more likely to report being victims of bullying. Victims of bullying reported more negative subjective health outcomes regardless of their D/CI status. Although inclusive education is currently a major topic of educational policies in most countries, additional efforts should be made to improve the quality of the integration of students with D/CI.

ABSTRACT: Colver A, Thyen U, Arnaud C, Beckung E, Fauconnier J, Marcelli M, McManus V, Michelsen SI, Parkes J, Parkinson K, Dickinson HO. Association between participation in life situations of children with cerebral palsy and their physical, social, and attitudinal environment: a cross-sectional multicenter European study. OBJECTIVE: To evaluate how participation of children with cerebral palsy (CP) varied with their environment. DESIGN: Home visits to children. Administration of Assessment of Life Habits and European Child Environment Questionnaires. Structural equation modeling of putative associations between specific domains of participation and environment, while allowing for severity of child's impairments and pain. SETTING: European regions with population-based registries of children with CP. PARTICIPANTS: Children (n=1174) aged 8 to 12 years were randomly selected from 8 population-based registries of children with CP in 6 European countries. Of these, 743 (63%) agreed to participate; 1 further region recruited 75 children from multiple sources. Thus, there were 818 children in the study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Participation in life situations. RESULTS: For the hypothesized associations, the models confirmed that higher participation was associated with better availability of environmental items. Higher participation in daily activities-mealtimes, health hygiene, personal care, and home life-was significantly associated with a better physical environment at home (P<.01). Mobility was associated with transport and physical environment in the community. Participation in social roles (responsibilities, relationships, recreation) was associated with attitudes of classmates and social support at home. School participation was associated with attitudes of teachers and therapists. Environment explained between 14% and 52% of the variation in participation. CONCLUSIONS: The findings confirmed the social model of disability. The physical, social, and attitudinal environment of disabled children influences their participation in everyday activities and social roles.

ABSTRACT: OBJECTIVE: To compare 3 methods of identifying small-for-gestational-age (SGA) status in very preterm children as related to cognitive function and academic outcome. STUDY DESIGN: There were 1038 singletons in the Epipage Study, born before 33 weeks in 1997 without severe neurosensory impairment, who were classified as SGA when birth weight was below the 10th percentile according to: (1) birth weight (bw) reference: SGA(bw)/appropriate for gestational age (AGA)(bw); (2) intrauterine (intraut) reference: SGA(intraut)/AGA(intraut); and (3) intrauterine reference customized (cust) according to individual characteristics: SGA(cust)/AGA(cust). Cognitive function was assessed by the mental processing composite (MPC) score of the Kaufman Assessment Battery for Children at age 5 and academic achievement by a parental questionnaire at age 8. RESULTS: Of the children, 15% were SGA(bw), 38% were SGA(intraut), and 39% were SGA(cust). All children SGA(bw) were also SGA(intraut) and SGA(cust). MPC was <85 in 32% of children and 27% had low academic achievement. AGA(bw)/SGA(intraut) children had a significantly increased risk of MPC <85 (adjusted OR 1.74, 95% CI 1.22-2.28) or low academic achievement (adjusted OR 1.64, 95% CI 1.05-2.55) compared with AGA(bw)/AGA(intraut) children. The SGA(cust) group was only slightly different from the SGA(intraut) group. CONCLUSIONS: An intrauterine reference identified very preterm infants at risk of poor cognitive or academic outcomes better than a birth weight reference. Customization resulted in only slight modifications of the SGA group.

ABSTRACT: BACKGROUND: SPARCLE is a study across nine European regions which examines the predictors of participation and quality of life of children with cerebral palsy. Children and their families were initially interviewed in 2004/2005 when the children were aged 8-12 years (SPARCLE1); they were approached again in 2009/2010 at age 13-17 years (SPARCLE2). The objective of this report is to assess potential for bias due to family non-response in SPARCLE2. Logistic regression was used to assess whether socio-demographic factors, parental stress and child impairment were related to non-response, both overall and by category (failure to trace families, death of child, traced families declining to participate). RESULTS: Of the 818 families who participated in SPARCLE1, 224/818 (27%) did not participate in SPARCLE2. 51/818 (6%) were not traced. Among the 767 traced families, 32/767 (4%) children with cerebral palsy had died, seven children had been incorrectly diagnosed as having cerebral palsy, thirteen families had moved out of the region and one family had language problems. Of the remaining 714 families, 120/714 (17%) declined to participate. Drop-out between SPARCLE1 and SPARCLE2 varied significantly between regions; families were more difficult to trace and more likely to decline to participate if the parents' educational qualifications, as recorded in SPARCLE1, were lower; they were also more likely to decline to participate if SPARCLE1 recorded that they were more stressed or if they had not completed a SPARCLE1 stress questionnaire. CONCLUSIONS: To reduce the risk of bias, all SPARCLE2 analyses should allow for factors (region and walking ability) which determined the sampling strategy, either by adjusting for these factors or by using sampling weights. Further analyses should be performed, adjusting for additional factors that were associated with non-response: parents' educational qualifications, family structure and parental stress. To allow for differential non-response in studies which sample from population registers, such registers should routinely record socio-demographic information.

ABSTRACT: Living with a child with a disability can affect family life in various domains. Impacts on time, expenses, work, relationships within the family, social relationships and physical and psychological health can be observed. The Family Impact of Childhood Disability (FICD) is a specific instrument designed to assess this situation. Used in a cross-sectional survey, this questionnaire was extended to consider two missing aspects: impact on work and health (FICD+4). This paper addresses the psychometric qualities of the FICD in Europe among parents living with an adolescent with cerebral palsy. Expecting the FICD+4 could assess detailed impact dimensions, an exploratory analysis was conducted. We interviewed 242 families of 13- to 17-year-old adolescents with cerebral palsy living in Europe. Good psychometric properties were found in negative and positive FICD scales and in six underlying factors extracted from exploratory factor analysis on FICD+4. These results support the psychometric validity of the FICD in the assessment of the impact of disability in European families who live with an adolescent with cerebral palsy. They also highlight the multifaceted aspects of the impact of childhood disability on the family and suggest that the FICD+4 is a good tool for assessing specific negative impacts on time, finances, work, social relationships and positive impacts on parental feeling and family attitude. This scale needs further validation and could be helpful for research and clinical interventions.

ABSTRACT: Peer victimization is a common problem among school-aged children, and those with chronic conditions are at an increased risk. A systematic review of the literature was carried out to explore the increased risk of peer victimization among children with chronic conditions compared with others, considering a variety of chronic conditions; and to assess intervention programs designed to reduce negative attitudes or peer victimization at school toward children with chronic conditions. Various data sources were used (PubMed, ERIC, PsycINFO, Web of Science), and 59 studies published between 1991 and 2011 and mainly carried out in North American and European countries were included in the review. A higher level of peer victimization among children with chronic conditions was shown for each type of condition explored in this review (psychiatric diagnoses, learning difficulties, physical and motor impairments, chronic illnesses, and overweight). Despite a substantial number of studies having shown a significant association between chronic conditions and peer victimization, intervention studies aiming to reduce bullying among these children were rarely evaluated. The findings of this review suggest a growing need to develop and implement specific interventions targeted at reducing peer victimization among children with chronic conditions.

ABSTRACT: To determine whether growth, feeding tolerance and infectious events of preterm infants is related to the proportion of intake of mother's own raw milk (maternal milk) versus pooled pasteurized banked breast milk (donor milk).
This is a prospective observational study of 55 premature infants born less than 32 weeks of gestational age admitted to the neonatal intensive care unit at the Children's Hospital of Toulouse during two 6-month periods from 2003 to 2005. Enrolled infants were exclusively on enteral feeds with maternal milk ± donor milk.
Mean gestational age was 28.6 weeks (SD 1.5) and mean birth weight 1105 grams (SD 282). During the time of exclusively breast milk feeds, weight gain (g/kg/day) was correlated to the proportion of maternal milk consumed (p = 0.0048, r = 0.4). Necrotizing enterocolitis was inversely correlated to the amount of maternal milk. The amount of maternal milk did not impact on infectious events.
Mother's own raw milk improves weight gain compared with donor milk in preterm infants. Lactation strategies should be sought that helps mothers to increase their milk production.

ABSTRACT: Prader-Willi syndrome (PWS) is a complex neurodevelopmental genetic disorder with hypothalamic dysfunction, early morbid obesity with hyperphagia, and specific psychiatric phenotypes including cognitive and behavioural problems, particularly disruptive behaviours and frequent temper outbursts that preclude socialization. A deficit in oxytocin (OT)-producing neurons of the hypothalamic paraventricular nucleus has been reported in these patients.
In a double-blind, randomised, placebo-controlled study, 24 adult patients with PWS received a single intranasal administration of 24 IU of OT or placebo and were tested 45 min later on social skills. Behaviours were carefully monitored and scored using an in-house grid as follows: over the two days before drug administration, on the half-day following administration, and over the subsequent two days. All patients were in a dedicated PWS centre with more than ten years of experience. Patients are regularly admitted to this controlled environment.
Patients with PWS who received a single intranasal administration of OT displayed significantly increased trust in others (P = 0.02) and decreased sadness tendencies (P = 0.02) with less disruptive behaviour (P = 0.03) in the two days following administration than did patients who received placebo. In the half-day following administration, we observed a trend towards less conflict with others (p = 0.07) in the OT group compared with the placebo group. Scores in tests assessing social skills were not significantly different between the two groups.
This study needs to be reproduced and adapted. It nevertheless opens new perspectives for patients with PWS and perhaps other syndromes with behavioural disturbances and obesity.

ABSTRACT: To explore bullying victimization among French and Irish students with a disability or chronic illness (D/CI), considering individual, social, and family factors. We investigated this issue in France and Ireland because of the documented differences between these two countries on relevant contextual factors.
Data from 12,048 students aged 11, 13, and 15 years (50.1% were boys) as part of the cross-national study 2006 Health Behaviour in School-aged Children were analyzed. Self-completion questionnaires were administered in classrooms; information on socio-demographic characteristics, bullying involvement, D/CI, school participation, social network, and family were collected. Multivariate logistic regressions were performed with individual, social, and family cofactors.
Overall, the prevalence of bullying victimization was significantly higher in France compared with Ireland (34.2% [33.1-35.5] and 25.9% [24.5-27.4, respectively]). Youngest were more likely to report victimization; however, no gender differences were observed. In both countries, students with D/CI were significantly more likely to report that they have been bullied compared with students without D/CI, and a significant additional risk of being bullied was found when students reported D/CI with restriction in school participation. Regardless of country and D/CI status, being bullied was significantly associated with weaker social support and difficulty of communication with fathers, with even stronger associations found among students with D/CI.
Adolescents with D/CI are more likely to be victimized than their peers, with a similar risk in both countries. Besides individual, social and family factors are consistently associated to bullying victimization across countries. These results will guide future antibullying prevention programs.

ABSTRACT: Children with Prader-Willi syndrome (PWS) are routinely treated with GH and have a response comparable with that observed in children with GH deficiency (GHD).
The objective of the study was to compare changes in serum IGF-I, IGF binding protein 3 (IGFBP-3), IGF-I to IGFBP-3 molar ratio, and growth velocity during the first 2 yr of GH therapy in PWS and GHD children.
Thirty-three children with PWS (14 boys, 4.9 ± 3.8 yr) and 591 with GHD (351 boys, 9.6 ± 3.6 yr), all naive to GH treatment, were included in this study. Serum IGF-I and IGFBP-3 were measured at 0, 6, 12, and 24 months of GH therapy. The mean initial dose of GH was 0.9 and 1 mg/m(2) · d in the PWS and GHD groups, respectively.
Mean ± SD IGF-I sdscore (SDS) and IGFBP-3 SDS were significantly higher in PWS compared with GHD. The IGF-I to IGFBP-3 molar ratio was significantly lower at baseline and subsequently not different. Despite significantly lower GH doses in PWS children at 6, 12, and 24 months (P = 0.021, P = 0.021, P = 0.001), IGF-I reached 2.8 ± 1.2 SDS at 24 months (72% of values > 2 SDS), and remained at 0.7 ± 1.6 SDS in GHD children (17% of values > 2 SDS). IGFBP-3 did not exceed 2 SDS in either group. There was no significant change in the IGF-I to IGFBP-3 molar ratio.
IGF-I SDS increases to a greater extent in PWS than GHD. Bioavailable IGF-I is apparently not different, suggesting that any possible safety issues related to elevated IGF-I are similar in both groups.

ABSTRACT: although inclusive education of disabled children is now an accepted practice, it is often challenged by negative peer attitudes. We undertook an interventional study aimed at improving students' attitudes towards their disabled peers.
the participants were students from the 7th grade of twelve paired schools (1509 students from 62 classes; age 12-13y), randomly allocated to an intervention group (205 males, 285 females) or a control group (132 males, 165 females). The intervention consisted of a mandatory comprehensive educational project on disability. The Chedoke-McMaster Attitudes Towards Children with Handicaps Scale (CATCH) was used to assess children's attitudes before (T0) and after (T1) intervention. The hierarchical structure of the data was taken into account by adjusting standard deviations and using linear multilevel models.
seven hundred and eighty-four students had at least one score on the three domains (cognitive, affective, behavioural) of the CATCH at T0 and T1. The final scores were higher than baseline scores (total scores, intervention group: baseline score 25.6 (SD=5.4), final score 26.8 (5.9), p<0.001; Control group: baseline 25.2 (5.4), final 26.0 (5.7), p<0.009) with no significant difference between the intervention and control groups. Individual score changes over time were associated with baseline score (p<0.001 for total and all sub-scores). Lower improvement in attitudes was found in students from schools with special units for their peers with cognitive impairment for total (p=0.013), affective (p<0.001), and behavioural (p=0.001) scores, while higher improvement existed for the cognitive domain (p=0.029).
although we found no effect of our intervention, we found an improvement in attitudes in the intervention and control groups that could be a result of the nature of the scales and questionnaires the students had to complete before the intervention.

ABSTRACT: The purpose of this study is to estimate the prevalence of faecal incontinence after first vaginal delivery and to assess the impact of Thierry's spatulas-assisted delivery.
A prospective observational study of primiparas who underwent a vaginal delivery at term was conducted. Faecal incontinence was assessed at 2 and 6 months postpartum by a questionnaire (Wexner score >or=5 was considered significant). Univariate and multivariate analyses were performed.
Five hundred thirty-eight women were recruited with undergoing 176 spatulas-assisted deliveries and 362 spontaneous vaginal deliveries. The response rate was 85.9% (2 months) and 80.5% (6 months). The prevalence of faecal incontinence was similar between the two groups at 2 months (14.3% and 9.7%). Episiotomy (odds ratio [OR] = 5.0) and maternal age over 35 years (OR = 4.1) were independently associated with faecal incontinence after adjustment.
Anal symptoms are common after the first vaginal delivery. Thierry's spatulas do not increase the prevalence of faecal incontinence after delivery given that an episiotomy is performed.

ABSTRACT: Prospective comparative study on 100 patients with positive family history for idiopathic scoliosis.
To evaluate the concordance rate for curve pattern and side in family members with idiopathic scoliosis.
The pathogenesis of idiopathic scoliosis has been the subject of extensive research. It is termed multifactorial with a genetic component. Similar curve shape has been reported in twins with idiopathic scoliosis.
We included prospectively 100 patients with idiopathic scoliosis when a relative of them was also affected with idiopathic scoliosis, and spine radiographs were available for both. Concordance for curve pattern by Lenke classification and side between family members was analyzed.
Familial concordance rate for curve pattern and side was 66% (95% confidence interval, 57-75), whereas the expected random concordance rate was 26% (95% confidence interval, 17-34). The affected relative was in 27 cases a sibling, in 32 cases a parent, in 1 case an uncle, in 2 cases a cousin, in 2 cases a half sister, in 2 cases a grandmother. Concordance rate was 65% (27/42) in siblings' pairs and 67% (32/48) in parents/child's pairs.
We report a high concordance rate for curve pattern and side between relatives with idiopathic scoliosis. Curve shape is likely to be genetically determined in familial scoliosis. It seems important that curve type is documented and considered in future genetic studies.

ABSTRACT: To compare cardiac MRI with right heart catheterisation in patients with pulmonary hypertension (PH) and to evaluate its ability to assess PH severity.
Forty patients were included. MRI included cine and phase-contrast sequences, study of ventricular function, cardiac cavity areas and ratios, position of the interventricular septum (IVS) in systole and diastole, and flow measurements. We defined four groups according to the severity of PH and three groups according to IVS position: A, normal position; B, abnormal in diastole; C, abnormal in diastole and systole.
IVS position was correlated with pulmonary artery pressures and PVR (pulmonary vascular resistance). Median pulmonary artery pressures and resistance were significantly higher in patients with an abnormal septal position compared with those with a normal position. Correlations were good between the right ventricular ejection fraction and PVR, right ventricular end-systolic volume and PAP, percentage of right ventricular area change and PVR, and diastolic and systolic ventricular area ratio and PVR. These parameters were significantly associated with PH severity.
Cardiac MRI can help to assess the severity of PH.

ABSTRACT: The UN Convention on the Rights of Persons with Disabilities requires states 'to ensure to persons with disabilities access, on an equal basis with others, to the physical environment, transportation, information and communications.' We explored whether this convention was respected for disabled children in Europe.
One thousand one-hundred and seventy-four children aged 8-12 years were randomly selected from population-based registers of children with cerebral palsy in eight European regions. 743 children joined the study; one further region recruited 75 children from multiple sources. Researchers visited these 818 children and administered the European Child Environment Questionnaire, which records parents' perceptions of availability of the physical, social and attitudinal environment needed in home, school and community. Multilevel, multivariable regression related child access on these domains to their impairments and socio-demographic characteristics.
Children with more impaired walking ability had less access to the physical environment, transport and social support they needed than other children. They also experienced less favourable attitudes from family and friends. However, attitudes of teachers and therapists were similar for children with all levels of impairment. The access of children, across all impairment severities, to their needed environment showed significant variation between regions (p ≤ 0.0001), some regions consistently providing better access on most or all domains.
European states need to substantially improve environmental access for disabled children in order to meet their obligations under UN Conventions. In some regions, many environmental factors should and realistically could be changed. Legislation and regulation should be directed to making this happen. Local environmental planners and health and social service providers should listen carefully to parents to address mismatches between policy intentions and parental experience.

ABSTRACT: Puberty is a transition period making physiological development a challenge adolescents have to face. Early pubertal development could be associated with higher risks of poor health. Our objective was to examine risk behaviours, physical and psychological determinants associated with early menarche (<11 years).
Early menarche was assessed in the Health Behaviour in School-aged Children French cross-sectional survey. Data were collected in 2006 by anonymous self-reported standardized questionnaire from a nationally representative sample of 1072 15 years old girls in school classrooms. Family environment, school experience, physical and psychological factors, risk behaviours (substance use and sexual initiation) were recorded. Logistic regression models were applied (analysing for crude and adjusted relationships between early menarche and risk behaviours controlled for family context).
Median age at menarche was 13.0 years; 57 girls (5.3%) were early-matured. Controlled for familial environment, early menarche was associated with having had more than two life-drunkenness episodes (adjusted OR = 2.5 [1.3-4.6]), early sexual initiation (adjusted OR = 2.8 [1.3-6.0]) and overweight (adjusted OR = 7.3 [3.6-14.9]).
Early-maturing girls may affiliate with older adolescents, hence engage in risk behaviours linked to their appearance rather than their maturity level. Factors associated with early menarche highlight the need to focus attention on early-matured girls to prevent further health problems linked to risk behaviours.
