BACKGROUND/OBJECTIVES: Although the association of body mass index (BMI) with metabolic syndrome (MetS) is well documented, there is little knowledge on the independent and joint associations of BMI and physical activity with MetS risk based on a continuous scoring system. This study was designed to explore the effect of physical activity on interactions between excess body weight and continuous metabolic syndrome (cMetS) in a nationwide survey of Iranian children and adolescents. SUBJECTS/METHODS: Data on 5,625 school students between 10 and 18 years of age were analyzed. BMI percentiles, screen time activity (STA), leisure time physical activity (LTPA) levels, and components of cMetS risk score were extracted. Standardized residuals (z-scores) were calculated for MetS components. Linear regression models were used to study the interactions between different combinations of cMetS, LTPA, and BMI percentiles. RESULTS: Overall, 984 (17.5%) subjects were underweight, whereas 501 (8.9%) and 451 (8%) participants were overweight and obese, respectively. All standardized values for cMetS components, except fasting blood glucose level, were directly correlated with BMI percentiles in all models (P-trend < 0.001); these associations were independent of STA and LTPA levels. Linear associations were also observed among LTPA and standardized residuals for blood pressure, high-density lipoprotein, and waist circumference (P-trend < 0.01). CONCLUSIONS: Our findings suggest that BMI percentiles are associated with cMetS risk score independent of LTPA and STA levels.

Objectives: Misperception of weight status is a risk factor that affects psychological health. The aim of this study was to evaluate the association between weight misperception patterns and psychological distress among Iranian children and adolescents. Methods: This was a cross-sectional nationwide study where data was collected from 14,440 students, aged 7–18 years who participated in the national school-based surveillance program (CASPIAN-V). The students’ weight perception and psychological distress were assessed by validated questionnaires. Weight misperception was classified as misperception of being either underweight or overweight with respect to actual weight. Results: The rate of weight misperception in all study participants was 59.1%. In groups with a perception of being underweight or overweight, the risks of worthlessness, being worried, experiencing aggression, insomnia, or depression, were significantly higher than groups with an accurate weight perception (p < 0.05). The risk of anxiety in girls of normal weight who perceived themselves as underweight, decreased by 57% compared to girls with an accurate weight perception (OR: 0.43; 95% CI, 0.28-0.66). Conclusion: Weight misperception is highly prevalent among Iranian children and adolescents and is associated with their psychological health status. Appropriate education intervention needs to be developed to improve the children and adolescents’ perception of their body weight status.
Goiter Frequency Is More Strongly Associated with Gastric Adenocarcinoma than Urine Iodine Level

Purpose: We designed our study to evaluate the hypothesis that gastric cancer is correlated with iodine deficiency or thyroid dysfunction. Materials and Methods: We investigated the total body iodine reserve, thyroid function status and autoimmune disorder in 40 recently diagnosed gastric adenocarcinoma cases versus 80 healthy controls. The participants came from a region with high gastric cancer rate but sufficient iodine supply due to salt iodination. The investigation included urine iodine level, thyroid gland clinical and ultrasonographic examination, and thyroid function tests. Results: Goiter was detected more frequently in the case group (P=0.001); such a finding, however, was not true for lower than normal urine iodine levels. The free T3 mean level was significantly lower in the case group compared to the control group (P=0.005). Conclusions: The higher prevalence of goiter rather than low levels of urinary iodine in gastric adenocarcinoma cases suggests that goiter, perhaps due to protracted but currently adjusted iodine deficiency, is more likely to be associated with gastric adenocarcinoma compared to the existing iodine deficiency itself.
