Background: the relationship between behavior clusters and weight status, mainly in low- and middle-income countries, remains unclear. This study aimed to examine the association between profiles of physical activity (PA), diet and sedentary behavior (SB) with weight status in adolescents from a southern Brazilian city, according to sex.
Methods: data from the Intervention study were analyzed ( = 812 / mean age 13.0 years (sd 1.04). Data on SB hours per day, PA minutes per week and weekly consumption frequencies of fruits, vegetables, salty snacks, candies and soda were self-reported on the validated questionnaire. Classes of healthy and unhealthy behaviors were derived by latent class analysis. Logistic regression analysis was used to estimate the associations between adolescents' weight status and classes.
Results: two classes were identified for the whole sample and for boys and girls. All classes had high probabilities of engaging high time in SB. Male adolescents in the unhealthy class had low probabilities of being active and high probability of consuming a low-quality diet. In contrast, girls' healthiest profile presented lower probabilities of being active compared to boys' healthiest profiles. No association was found between weight status and classes.
Conclusion: All classes had at least one unhealthy behavior, for both the whole sample, and for girls and boys. Girls' profiles were unhealthier compared to boys' profiles. Hence, it is recommended that intervention strategies to change behaviors need to be distinct according to sex, targeting more than one obesogenic behavior at the same time.

Background: Despite the integration of iron supplementation into routine antenatal care programs as a nutritional intervention to prevent anemia in pregnant women, the use of this supplement for the recommended duration remains low in sub-Saharan Africa (SSA). Evidence on maternal compliance with iron supplementation at the SSA level is lacking and most of the previous studies have been limited to specific geographic areas. Therefore, the current study used large population survey data from 35 SSA countries to estimate the pooled prevalence of non-adherence and its determinants.

Metabolic syndrome during menopause can lead to diabetes, cardiovascular problems, and increased mortality rates. Hormone replacement therapy is recommended to manage climacteric complications, but it has serious adverse effects. This study, therefore, investigated the potential of supplementing some minerals, vitamins, and natural products like boric acid, magnesium, vitamin D3, and extra virgin olive oil on metabolic status of menopausal ovariectomized rats.
