To compare treatment, sex, and visit differences in beverage choice and calcium intake in the Dietary Intervention Study in Children, to compare the relationship of other beverages to milk consumption, and document whether or not the dietary intervention affected choice of beverage and milk type over time.
Data from the Dietary Intervention Study in Children, a randomized, controlled, multicenter, clinical trial with five sets of three 24-hour recalls.
Six hundred fifty-three children from six clinics started the study at age 8 to 10 years. Participants had serum low-density lipoprotein cholesterol levels between the 80th and 98th percentiles of age, and were followed for a median of 7.3 years.
Children were randomized to a total fat- and saturated fat-modified dietary intervention or usual care.
Volume and percent of total energy from soft drinks, fruit-flavored drinks, fruit juice, and milk, calcium intake in milligrams and per 1,000 kcal, and percent reduced-fat and skim milk consumed.
General Estimating Equations methodology was used to adjust for treatment, sex, and visit differences.
The intervention group consumed more reduced-fat or skim milk than the usual care group. The intervention group also reported a greater increase in calcium per 1,000 kcal than those in the usual care group due to nonbeverage sources. Consumption of soft drinks increased over the course of the study, whereas total milk consumption decreased sharply.
With nutrition education, children can make changes in the type of milk consumed, and in the quantity of dietary calcium consumed.

    ABSTRACT: Atherosclerosis is a result of a lifelong process. Obesity is associated with increased serum levels of inflammatory markers in children and adolescents like in adults, promoting coronary heart disease risk in an increasing proportion of young adults. Dietary patterns have a central role in the development of coronary heart disease through effects on serum lipids and development of body fatness. It is the purpose of this review to describe progress in this field. The supervised counselling aiming at low saturated fat intake by children decreases serum total and low-density lipoprotein (LDL) cholesterol values significantly and keeps them at lower level through childhood. It is not associated with abnormal growth or defects in cognitive or pubertal development. Coronary heart disease risk factor levels measured in childhood markedly influence vascular function and structure. To diminish the risk of premature atherosclerosis, the prime target in counselling of young children and their parents should be a change in fat quality rather than fat quantity. However, to prevent obesity, excessive consumption of total fat and sucrose needs to be avoided. Early commencement of statin therapy in children and adolescents suffering from familial hypercholesterolemia is beneficial in prevention of vascular atherosclerosis.

    ABSTRACT: This was to study the intakes of sweet drinks and sweet treats of children and their caries risk using the Paediatric Risk Assessment Tool (PRAT, 2003) and Caries-risk Assessment Tool (CAT, 2007-8). Parents of 266 healthy primary school children completed the PRAT questionnaire during their child's dental appointment at the Royal Dental Hospital of Melbourne, Australia, describing their fluid and sweet treat intakes in the past 24 hours, oral hygiene practices and past caries. A subgroup (n=100) was examined clinically (CAT) for caries requiring restoration, visible plaque, gingivitis, orthodontic appliances, enamel defects, and use of dental care. The estimated mean daily fluid intake was 1.5+/-0.5L; fluids were consumed 3-5/ day by 57% of children and 78% usually had evening/night drinks. Fluids consumed were: tap water by 90%, milk by 74%, juice by 50%, regular soft drink by 30%; sweet treats were consumed by 62% and confectionery by 25%. Most children (69%) brushed their teeth > or =2/day; 5% flossed daily. Parentally-reported caries was associated significantly with increasing treats frequency (p=0.006). In the subgroup, 81% were at high caries risk; 47% had irregular dental care; 21% had sweet drinks/foods frequently between meals; 49% had visible plaque/gingivitis, and 34% had enamel demineralisation. Caries observed in the past 12 months was associated significantly with evening sweet drinks (p=0.004), and suboptimal fluoride exposure (p=0.009). Caries observed in the past 24 months was associated significantly with treats frequency (p=0.006), intake of sweet drinks plus treats (p=0.000), enamel demineralisation (p=0.000) and irregular dental care (p=0.000). The PRAT and CAT are valuable tools in assessing children's caries risk. The risk of caries from frequent intake of sweet drinks, either alone or in addition to sweet treats, must be emphasised to parents. All parents, and particularly those of children assessed at high risk from intakes of sweet drinks and sweet treats, suboptimal fluoride exposure, or enamel demineralisation, must be encouraged to obtain regular dental care for their children.

    ABSTRACT: In Australia, caries experience of 6-year-old and 12-year-old children has increased since the mid to late 1990s. Previously, caries rates had declined, attributable to community water fluoridation. The recent caries increase has been attributed speculatively to changes in fluid intake, including increased consumption of sweet drinks and bottled waters. Increasing urbanization and globalization have altered children's diets worldwide, promoting availability and access to processed foods and sweet drinks. Studies in Australia and internationally have demonstrated significant associations between sweet drink intake and caries experience. Despite widespread fluoride availability in contemporary Australian society, the relationship between sugar consumption and caries development continues and restricting sugar intake remains key to caries prevention. Caries risk assessment should be included in treatment planning for all children; parents should be advised of their child's risk level and given information on oral health promotion. Readily-implemented caries risk assessment tools applicable to parents and clinicians are now available. Public health information should increase awareness that consuming sweet drinks can have deleterious effects on the dentition as well as the potential for promoting systemic disease. Restricting sales of sweet drinks and sweet foods and providing healthy food and drinks for purchase in schools is paramount.
