Childhood obesity epidemic has become a public health issue in the USA, especially among African American youths. Research on the association between ideal body image (IBI) and obesity and related lifestyle factors among African American children and adolescents is limited.
Data collected from 402 low-income African American adolescents aged 10-14 years in four Chicago public schools were used. Questionnaires were used to assess IBI, weight perception, weight control practices, and self-efficacy towards food and physical activity. Body mass index was calculated using measured weight and height. Associations between IBI and weight perception, overweight/obesity and lifestyle behaviours were assessed using linear and logistic regression models.
The most frequently chosen ideal body size was the fourth of eight silhouettes (from thinnest to heaviest) for boys (55%) and girls (49%). Overweight and obese girls selected larger ideal body figures than the others (trend test: P < 0.001). Compared with those with middle ideal body figures, girls who selected smaller ones were twice as likely to have an unhealthy diet as indicated by less fruit and milk consumption; the odds ratios (ORs) and 95% confidence intervals (95% CIs) were 2.40 (1.15-5.02) for fruits intake (<once/week) and 2.13 (1.06-4.29) for milk consumption (<once/day), respectively. Boys with larger IBI were less likely to eat snack often [≥once/day; OR = 0.11 (0.02-0.50)]. Girls with larger IBI were less likely to spend more screen time [OR = 0.12 (0.02-0.70)] and reported better food choice intentions (P < 0.05). Overweight and obese boys and girls appeared to have better food choice intentions and food self-efficacy than their non-overweight peers (trend test: both P < 0.01).
Ideal body image is associated with weight status, food self-efficacy and lifestyle behaviours among low-income African American adolescents.

    • "Weight underestimating African-American female adolescents also had unhealthy dietary practices, such as consuming less than the recommended number of servings of fruits and dairy per day. However, weight overestimating male adolescents were less likely to consume snacks [28]. We also found that weight misperceiving girls seemed to skip breakfast frequently and that weight overestimating girls consumed fast foods and regular sodas more frequently. "

    ABSTRACT: There is little information on the association between weight misperception and eating behavior in Korean adolescents. Therefore, we investigated the association of food intake habits and dieting method and disturbed eating behavior (DEB) in relation to weight misperception. Data was collected by using a nationwide online panel survey from 6,943 adolescents enrolled in middle/high school. DEB was measured with the Eating Attitudes Test (EAT-26) and those who scored ≥ 20 on the EAT-26 were considered to have eating disorder. Logistic regressions were conducted to examine the association between weight misperception based on self-reported weight status and dieting method and eating behaviors. The proportion of weight underestimation was 23.5% and that of overestimation was 24.0%. Weight overestimating girls were more likely to engage in various unhealthy dieting practices (OR = 1.69 for fasting; OR = 1.88 for laxative or diuretic use; OR = 2.05 for self-induced vomiting after meals; P < 0.05). Moreover, there was a strong association between overestimation and undesirable eating behaviors, especially among girls, e.g.: having breakfast (OR = 0.85), high consumption of fast foods (OR = 1.28) and regular sodas (OR = 1.39), but not among boys. In both genders, weight overestimation appears to be a major risk factor for DEB (OR = 1.34 for boys and OR = 1.41 for girls; P < 0.05). Weight overestimation is associated with unhealthy weight control practices and eating behaviors. We particularly found a significant association between weight overestimation and DEB among nationwide Korean adolescents.

    ABSTRACT: This paper examined the importance of household and economic contextual factors as determinants of ethnic disparities in adolescent body mass index (BMI). Individual-level data from the National Longitudinal Survey of Youth 1997 for the years 1997 through 2000 were combined with economic contextual data on food prices, outlet density and median household income. The Oaxaca-Blinder decomposition method was used to examine the factors that could help explain ethnic disparities in BMI. Ethnic differences in household demographic, parental socioeconomic status (SES), and economic contextual factors explained the majority of the male black-white (63%), male Hispanic-white (78%) and female Hispanic-white (62%) BMI gaps but less than one-half of the female black-white BMI gap (44%). We found that adding the economic contextual factors increased the explained portion of the ethnic BMI gap for both female and male adolescents: the economic contextual factors explained 28% and 38% of the black-white and Hispanic-white BMI gaps for males and 13% and 8% of the black-white and Hispanic-white BMI gaps for females, respectively. Parental SES was more important in explaining the Hispanic-white BMI gap than the black-white BMI gap for both genders, whereas neighborhood economic contextual factors were more important in explaining the male BMI gap than the female BMI gap for both black-white and Hispanic-white ethnic disparities. A significantly large portion of the ethnic BMI gap, however, remained unexplained between black and white female adolescents.

    ABSTRACT: This article summarizes the current situation of one of the most important XXI century epidemics. The high rates of obesity in all countries and specially in our country at early ages are worrying. Traditionally, investigations have focused on the most nutritional aspects, such us dietary factors, metabolism, calory intake and energy expenditure. However, other sciences -such as Psychology- point out new influencing factors, such as food addiction, depression, stress and anxiety. In this piece of work, more than 80 articles from all disciplines and different databases and related to obesity are analyzed, as well as a new theoretical approach is proposed to ensure a more accurate comprehension. The literature review shows the necessary evidence to introduce a new model of obesity named edorexia, and raise issues to be resolved in future research oriented from a multidisciplinary perspective.
