Objective: To examine the relationship between television (TV) viewing and body mass index (BMI) among adolescents in a region of mainland China. Design: Population-based cross-sectional study, conducted between September and November of 2004, on a sample of enrolled high-school students aged 12-18 years. Setting: One hundred and sixty-eight classes randomly selected from both urban and rural areas and belonging to 15 senior and 41 junior high schools in Nanjing, China, with a regional population of 6Á0 million. Subjects: In total 6848 students participated; 47Á7 % from urban and 52Á3 % from rural areas; 49Á0 % male and 51Á0 % female. The response rate among eligible participants was 89Á3 %. Results: The proportion of overweight was 6Á6 % according to the criteria of overweight recommended for Chinese adolescents. Boys than girls (8Á9 % vs. 4Á4 %) had higher odds of being overweight (odds ratio (OR) 2Á12, 95 % confidence interval (CI) 1Á74, 2Á60), while the proportion of overweight was significantly lower among rural students than urban students (4Á5 % vs. 8Á9 %; OR 0Á49, 95 % CI 0Á40, 0Á60). Those students who watched TV for more than 7 h/week had a 1Á5 times greater odds of being overweight relative to their counterparts who watched TV for 7 h/week or less (adjusted OR 1Á51, 95 % CI 1Á24, 1Á82). Furthermore, there was a positive linear relationship between TV viewing time and BMI, even after adjusting for age, gender, residence area, time spent in study, in sleeping and in physical activity, and monthly pocket money. Conclusions: Viewing TV might increase the likelihood of being overweight for Chinese adolescents in China.

“…difficult because of the diversity of criteria used for the definition of nutritional status since no standard or reference was agreed upon internationally (35) . Different estimates of nutritional status may also be found when factors such as age, gender and also the time at which the study was conducted are taken into consideration, especially in Brazil where rapid nutritional transition has been observed over the past 10 years (36) .…”

Objective: To evaluate the association between overweight and the occurrence of asthma and atopy in a cohort of children of 4-12 years of age living in the city of Salvador in 2005. Design: Cross-sectional study nested in a cohort. Setting: The metropolitan region of Salvador, Bahia, Brazil. Subjects: The study included 1129 children of 4-12 years age who presented complete information on the variables used here. Skin tests for allergy, spirometry, faecal parasitology, serum IgE and anthropometric surveys were conducted. Poisson's multivariate regression was adopted. Results: Wheezing was found in 29?1% and asthma in 22?8 % of children, both conditions being more common in those under 6 years of age and 34 % more common in overweight children (prevalence ratio (PR) 5 1?34; 95 % CI 1?07, 1?67) following adjustment. The ratio between forced expiratory volume in 1 s and forced vital capacity was associated with overweight (PR 5 1?35; 95 % CI 1?11, 1?61). No statistically significant association was found between overweight and allergen-specific IgE or with wheezing. Conclusions: These results are in agreement with the hypothesis that overweight is associated with asthma and pulmonary function, even following adjustment for intervening variables known to be associated with the pathogeny of asthma.

Objective: To delineate a classification system, comprising reference curves and cutoff points, based on the distribution of body mass index (BMI) across a national reference population and designed for the assessment of the nutritional status of Brazilian children and adolescents.Methods: Data from 13,279 males and 12,823 females aged from 2 to 19 years, extracted from the National Nutrition and Health Survey dataset (1989), were used to construct a reference curve. The LMS method was employed to calculate the BMI curve parameters and polynomial functions were used to model these parameters against age. The cutoff values for classifying nutritional status as underweight, overweight and obese were expressed as centiles and BMI values equivalent to 17.5, 25 and 30 kg/m 2 at 20 years, respectively.Results: Values for the L, M and S parameters were tabulated at 6-month intervals for each sex. Using these values, a graph was plotted with nine BMI distribution reference centiles. Cutoff values were presented that are equivalent to BMIs of 17.5, 25 and 30 kg/m 2 at the start of adulthood. Conclusions:The classification system presented here can be used for clinical and epidemiological assessments, it is methodologically similar to the majority of national curves that have been presented to date and, furthermore, it offers a definition of underweight.
