RESUMO
BACKGROUND: Assessing diet quality has been challenging, and the associations of diet quality and daily free sugar intake with depressive and/or anxiety symptoms have shown inconsistency. METHODS: A total of 1749 students aged 12-16 years were recruited using stratified random cluster sampling across three cities in China. The overall Global Dietary Recommendations (GDR) score, a novel indicator of diet quality, was constructed using the low-burden Diet Quality Questionnaire. Free sugar intake, including from beverages and foods, was measured using the Food Frequency Questionnaire. Daily free sugar intake was divided into low, medium, and high categories based on the latest version of the dietary guidelines for Chinese residents. Binomial and multinominal logistic regression analyses were used to examine the associations of the overall GDR score and daily free sugar intake categories or different sources of free sugar intake with depressive and/or anxiety symptoms. RESULTS: The overall GDR score was negatively associated with depressive symptoms (adjusted odds ratio[aOR] = 0.92, 95%CI: 0.87-0.98) and anxiety symptoms (0.95, 0.90-0.99), particularly with comorbid depression and anxiety (0.90, 0.84-0.97). Conversely, daily free sugar intake was positively associated with symptoms of depression and/or anxiety, the multiple aOR for symptoms depression or anxiety were significantly increased with higher daily free sugar intake (all Ptrend < 0.05). Both free sugar from beverages and from foods were positively associated with depressive and/or anxiety symptoms. These associations were consistent between males and females. LIMITATIONS: Cross-sectional design and self-reported symptoms. CONCLUSIONS: Diet quality was negatively associated with symptoms of depression or anxiety, especially with comorbid symptoms among adolescents. Daily free sugar intake, regardless of its sources, was positively associated with symptoms of depression and/or anxiety.

Importance: In China, parental labor migration often leaves children behind and is potentially adversely associated with children's health. However, the association between parental migration and aggression among their offspring remains largely underexplored. Objective: To investigate the associations of parental labor migration with total and subtypes of aggression among their offspring as well as potential sex differences therein. Design, Setting, and Participants: This cross-sectional study was conducted from February to October 2015 among students aged 11 to 20 years from 45 public middle and high schools across 5 provinces of China. Data analysis was performed from December 1, 2022, to August 1, 2023. Exposures: Parental migration, including migration status (yes or no), pattern (father, mother, or both), and the child's age at the initial parent-child separation. Main Outcomes and Measures: Total and subtypes of aggression (including physical aggression [PA], verbal aggression [VA], indirect aggression [IA], anger, and hostility) were measured using the Chinese version of the Buss-Warren Aggression Questionnaire. Binomial logistic regression analyses were used separately to estimate adjusted odds ratios (aORs) and 95% CIs of parental migration by total and subtypes of aggression. Results: A total of 15â¯301 participants (7900 [51.6%] male and 7401 [48.4%] female) aged 11 to 20 years (mean [SD] age, 15.1 [1.8] years) were included. Of these participants, 5961 (39.0%) experienced parental migration; 2451 (16.0%) met the criteria for total aggression, 2407 (15.7%) for PA, 2283 (14.9%) for VA, 2899 (18.9%) for IA, 2307 (15.1%) for anger, and 2564 (16.8%) for hostility. Parental migration was associated with total aggression (aOR, 1.11; 95% CI, 1.01-1.22); no significant association between parental migration and subtypes of aggression was found except for PA (aOR, 1.14; 95% CI, 1.03-1.25). Compared with children whose parents did not migrate, the aORs for total aggression and PA for participants whose father migrated were 1.12 (95% CI, 1.01-1.28) and 1.15 (95% CI, 1.03-1.29), respectively; for participants with both parents having migrated, the aORs were 1.16 (95% CI, 1.02-1.31) and 1.12 (95% CI, 1.04-1.24), respectively. Compared with children whose parents did not migrate, children who experienced initial separation from 1 or both parents at adolescence had an aOR for total aggression of 1.20 (95% CI, 1.04-1.36), children who experienced initial separation from 1 or both parents at school age or adolescence had an aOR for PA of 1.15 (95% CI, 1.01-1.32) and 1.26 (95% CI, 1.04-1.51), respectively. No sex differences were found in these associations. Conclusions and Relevance: In this cross-sectional study of Chinese children and adolescents, we found that parental migration, mainly of the father or both parents or an initial separation at adolescence or school age from 1 or both parents, was associated with higher odds of total aggression and PA among offspring. These associations were similar between male and female participants.
