Little is known about how behaviors to control weight are associated with diet quality among youth from low- and middle-income countries. The aim of this study was to examine associations between efforts to control weight (ECW) and diet quality among Brazilian adolescents and young adults.
Data from 731 participants (17.89 ± 4.92 years, 51.1% female) of the 2015 Health Survey of São Paulo were used for this cross-sectional study. Dietary intake was assessed using a 24 h dietary recall and diet quality was calculated using the Brazilian Healthy Eating Index-Revised (BHEI-R). Participants reported their ECW, weight satisfaction, and socio-demographics. Descriptive statistics and linear regressions were calculated to investigate associations between ECW and diet quality.
Approximately 47.7% of participants were dissatisfied with their current weight, and 41.0% reported ECW. Reported strategies to control weight included increased physical activity, taking care of what they eat, and dieting (8.2, 3.1, and 2.5%, respectively). After adjusting for age, sex, race/ethnicity, and body mass index, reporting at least one ECW (ß = 0.08; 95% CI 0.02, 0.13), taking care of what to eat (ß = 0.15; 0.08, 0.22) and being satisfied with their weight (0.08; 0.02, 0.13) were all associated with a higher overall BHEI-R score.
Overall diet quality score showed a small increase in participants reporting ECW. Further studies should be conducted to provide strategies used by adolescents from low- and middle-income countries to control their weight. Thus, developing public health policies, and behavioral-change strategies.

关于来自中低收入国家的年轻人控制体重的行为如何与饮食质量相关，目前知之甚少。本研究的目的是检验巴西青少年和年轻成年人控制体重的努力（ECW）与饮食质量之间的关联。
本横断面研究使用了 2015 年圣保罗健康调查的 731 名参与者（17.89±4.92 岁，51.1%为女性）的数据。饮食摄入通过 24 小时膳食回忆进行评估，饮食质量使用巴西健康饮食指数修订版（BHEI-R）进行计算。参与者报告了他们的 ECW、体重满意度和社会人口统计学资料。计算了描述性统计和线性回归，以调查 ECW 与饮食质量之间的关联。
约 47.7%的参与者对自己目前的体重不满意，41.0%的人报告了 ECW。报告的控制体重的策略包括增加体力活动、注意饮食和节食（分别为 8.2%、3.1%和 2.5%）。在调整年龄、性别、种族/民族和体重指数后，报告至少有一种 ECW（β=0.08；95%置信区间 0.02，0.13）、注意饮食（β=0.15；0.08，0.22）和对体重满意（0.08；0.02，0.13）均与总体 BHEI-R 评分较高相关。
报告 ECW 的参与者的总体饮食质量评分略有增加。应进一步开展研究，以提供来自中低收入国家的青少年控制体重所使用的策略。从而制定公共卫生政策和行为改变策略。
