“…Although certain differences in type of physical exercise can be found, the studies available in the literature agree that this practice tends to be negatively associated with age, especially beginning in the last years of adolescence 15,16 . Although several studies have sought to identify the reasons for such decrease, the proportion of contribution of biological and environmental factors and their interaction to the reduction in physical activity with age remain unclear.…”

The objective of this study was to identify the frequency of practice of exercise and fruit/vegetable intake in a representative sample of Brazilian university students and their possible association with nutritional status. The sample consisted of 1177 individuals of both sexes, aged 18-35 years, selected randomly. Information about the frequency of exercise and fruit/vegetable intake was obtained with the National College Health Assessment-II self-administered questionnaire. Nutritional status was defined based on body mass index according to the cut-off values recommended by the World Health Organization. The results showed that the practice of cardio-respiratory and resistance exercises were reported by 51.5% and 32.5% of the sample, respectively. Less than 4% of the university students had an adequate fruit/vegetable intake. Proportion of occurrence of excess body weight was equivalent to 32.4%, being significantly higher in men (45.6% vs 22.33%; p < 0.005). The risk to identify excess body weight in university students who reported not consuming fruits/vegetables daily was two to three times higher than their peers who reported an adequate intake (women: OR = 2.89 [95%CI: 2.28 -3.62]; men: OR = 1.96 [95%CI: 1.44 -2.60]). Exposure risk for excess body weight was progressively lower according to reported higher frequency of practice of cardio-respiratory exercise. In conclusion, the findings suggest immediate interventions aimed at emphasizing the healthy practice of exercise and food intake could help to minimize the risk of appearance and development of excess body weight.

In addition, girls show relatively less energy consuming hyperactive and impulsive behavior in relation to inattentive behavior than boys.…”

Association of symptoms of attention-deficit/hyperactivity disorder with childhood overweight adjusted for confounding parental variables

OBJECTIVE: There have been numerous reports on association between attention-deficit/hyperactivity disorder (ADHD) and overweight/obesity in children and adolescents; however, most studies adjusted only for a limited number of possible confounders. METHODS: We analyzed the data of 11 159 six through seventeen-year-old participants in the German Health Interview and Examination Survey for Children and Adolescents. We determined weight status based on measured anthropometry and national reference data by International Obesity Task Force criteria. The parent-rated hyperactivity/inattention subscale of the Strengths and Difficulties Questionnaire (SDQ-HI) was used as a continuous measure of ADHD symptoms. We examined whether the putative confounders socioeconomic status, migrant status, parental body mass index (BMI) and parental smoking were associated with both SDQ-HI and overweight/obesity. Associations between SDQ-HI and overweight/obesity vs normal weight were analyzed by binary logistic regression analyses. In the first model, we adjusted for age and sex only and in the second model also for the parental confounders. RESULTS: SDQ-HI was associated with an increased risk for overweight/obesity in both sexes adjusting for age and sex. However, after adjusting for all confounders SDQ-HI was associated with an increased risk for overweight/obesity only in adolescent females. Socioeconomic status, parental BMI and parental smoking each were relevant confounders. Migrant status was also significantly associated with both SDQ-HI and overweight/obesity, thus qualifying as a confounder but contributed only weakly to the association. CONCLUSIONS: The association between ADHD symptoms and overweight/obesity is due to confounding by family background variables in all but adolescent girls. Possible reasons for the increased risk for overweight/obesity in this subgroup are discussed. We also propose possible mechanisms for confounding by parental socioeconomic status, BMI and smoking.

“…could this be generalized to adolescent females? In this sense, it is important to mention that physical activity levels tend to decline as children get older [12,13], particularly during adolescence [22] and above all among females [23]. Furthermore, there is a worldwide prevalence of low physical activity levels in adolescents, also mainly among females [24].…”

Purpose. The aim of this study was to analyze the interrelationships among motor coordination, body fat percentage, and physical activity levels in adolescent girls. Methods. Sixty-eight girls aged 12-14 years participated in the study. Skinfold thickness was measured and the Körperkoordinationstest für Kinder test was administered. Participants completed a self-reporting questionnaire on physical activity. Bivariate and partial correlations were used to analyze the interrelationships among the selected variables. Results. There were no significant (p > 0.05) correlations between any motor coordination scores and physical activity levels with and without controlling for body fat percentage. All motor coordination scores were significantly (p < 0.05) associated with body fat with and without controlling for physical activity levels. Conclusions. The relationships between motor coordination scores and physical activity levels, as well as between motor coordination scores and body fat percentage, were not influenced by body fat and physical activity levels, respectively. However, the overall low physical activity level in this sample may have biased these results. Additional research involving girls with higher physical activity levels should be pursued.
