饮食行为对中小学生健康相关生活质量影响

Association of dietary behaviors with health-related quality of life among primary and high school students in urban and rural Nanjing, China

摘要

摘要:
目的了解江苏省南京城乡地区中小学生不健康饮食行为与健康相关生活质量的关联。
方法于2018年5 — 6月，随机抽取南京市全部城乡行政区4～12年级的在校中小学生为研究对象，使用Child Health Utility 9D（CHU9D）评价学生的健康相关生活质量，使用多水平线性回归模型分析饮食行为与健康相关生活质量之间的关联。
结果共调查4388名学生，CHU9D的平均分值为（0.78 ± 0.17）分。调整了可能的影响因素和班级水平的潜在聚集效应之后，与摄入频次较高者相比，蔬菜和水果摄入较少者的健康相关生活质量CHU9D评分分别下降0.022（95 % CI = – 0.043～– 0.001）和0.015（95 % CI = – 0.034～0.004）；而与摄入频次较少者相比，快餐和软饮料摄入较多者的CHU9D分值分别降低0.030（95 % CI = – 0.041～– 0.020）和0.024（95 % CI = – 0.034～– 0.013）。同时，针对蔬菜、水果摄入较少和快餐、软饮料摄入较多4种不健康饮食行为，经多因素调整后，研究对象每合并增加一种不健康饮食行为，其健康相关生活质量评分下降0.02（95 % CI = – 0.03～– 0.01）。
结论在中小学生中，蔬菜、水果的食用频次与健康相关生活质量之间存在负向关联，而快餐、软饮料的食用频次与健康相关生活质量之间则存在正向关联。4种饮食行为对健康相关生活质量的影响存在协同效应。

Abstract:
Objective To explore the correlation between dietary behaviors and health-related quality of life (HRQoL) among primary and high school students in urban and rural regions of Nanjing municipality, China.
Methods Using multistage random cluster sampling, we recruited 4 498 students of grade 4 – 12 in 108 classes of 36 primary and junior/senior high schools in all administrative districts of Nanjing. On-site self-administered questionnaire survey and anthropometric measurement were conducted among the students during May – June 2018. Child Health Utility 9D – Chinese Version (CHU9D-CHN), Item-Specific Physical Activity Scale for Chinese Children and Adolescents (I-PASCA), and the Food Frequency Questionnaire were adopted in the survey. Multivariate linear regression model was used to analyze the association of dietary behavior with HRQoL among the students.
Results For the 4388 participants completed the survey (response rate = 97.6%), the mean value of HRQoL was 0.78 (standard deviation = 0.17). After adjusting for confounders and potential class-level clustering effects, the score of CHU9D decreased for the students with low frequency of vegetable intakes (mean difference MD = – 0.022, 95% confidence interval 95% CI: – 0.043 – – 0.001) and fruit intakes (MD = – 0.015, 95% CI: – 0.034 – 0.004) compared to those with high frequency of vegetable and fruit intakes; decreased CHU9D scores were also measured in the students with high consumption frequency of snack (MD = – 0.030, 95% CI: – 0.041 – – 0.020) and soft-drink (MD = – 0.024, 95% CI: – 0.034 – – 0.013) in comparison to those with low frequency of snack and soft-drink consumption; moreover, the results of multivariate analysis demonstrated that a – 0.22 (95% CI: – 0.03 – – 0.01) increment in the CHU9D score was correlated with each of the four unhealthy dilatory behaviors additively (low intake of vegetable and fruit and high consumption of snack and soft-drink) after adjusting for other variables.
Conclusion The intake frequency of vegetables and fruits are inversely associated with HRQoL, but the frequency of snack and soft-drink consumption are positively correlated to HRQoL; the four dietary behaviors are of synergistic effect on HRQoL among primary and high school students in Nanjing, China
