RESUMO
<p><b>OBJECTIVE</b>To in vestigate potential gender differences in the odds of overweight/obese, weight-related perceptions, and behaviors among Chinese school children.</p><p><b>METHODS</b>Height, weight, and a survey of weight-related perceptions and behaviors were measured in a nationally representative survey of 12,811 children in primary schools in China. Logistic regression analyses were used to assess gender differences, adjusting for confounders.</p><p><b>RESULTS</b>Boys had higher odds of being overweight/obese compared to girls within both urban [adjusted odds ratio (OR) 2.30, 95% CI 2.00 to 2.65] and rural areas (OR = 1.85, 95% CI 1.55 to 2.20). Girls reported healthier diets (e.g., daily vegetables OR = 0.79, 95% CI 0.73 to 0.85) whereas boys consumed fried food (OR = 1.21, 95% CI 1.06 to 1.38) and sugar-sweetened drinks more often (OR = 1.49, 95% CI 1.34 to 1.65). Gender differences included higher odds of boys perceiving themselves as overweight if they had more highly educated mothers (OR = 1.35, 95% CI 1.09 to 1.68), less educated fathers (OR = 0.79, 95% CI 0.63 to 0.99), and if they frequently consumed carbonated drinks (OR = 1.48, 95% CI 1.07 to 2.05).</p><p><b>CONCLUSION</b>Childhood obesity prevention in China should be gender-focused, particularly for boys who reported an unhealthier diet but were less likely to see they were fat, even though more boys were overweight or obese than girls.</p>
RESUMO
ObjectiveTo systematically review the literature on the impact of the COVID-19 pandemic on deaths of despair (suicide, overdoses and drug-related liver diseases). MethodsFive electronic databases were searched using search terms on deaths of despair and COVID-19. ResultsThe review of 70 publications included indicates that there is no change or a decline in the suicide rate during the pandemic compared to the pre-pandemic period. Drug-related deaths such as overdose deaths and liver diseases, however, have been increased compared to the pre-pandemic rate. Findings are mainly from middle-high- and high-income countries and data from low-income countries are lacking. Synthesis of data from subgroup analysis indicates that some groups such as Black people, women and younger age groups would be more vulnerable to socioeconomic disruption during the pandemic. ConclusionStudies included in this review were preliminary and suffered from methodological limitations such as lack of inferential analysis or using provisional data. Further high-quality studies are needed considering the contribution of factors such as disease prevalence, government intervention and environmental characteristics.
