Analysis of Adverse Dietary Behavior and Its Influencing Factors among Early Adolescents in a City of Guangxi

Abstract

Objective: To explore the situation of poor eating behavior in adolescents in early adolescence, analyze its influencing factors, and provide a theoretical basis for adolescents to formulate effective dietary intervention methods and nutrition improvement strategies. Methods: In April~November 2019, 1200 students were randomly selected according to the principle of stratified cluster random sampling in a city in Guangxi, and 1089 valid questionnaires were collected. General data use descriptive statistics, univariate analysis uses tests and t/t' tests, and logistic multivariate regression analysis is used to determine relevant factors. Results: (1) 806 adolescents (74.01%) were detected with bad eating behavior in early adolescence in a city in Guangxi, and the adolescents with bad eating behavior were older (P<0.001). (2) Univariate analysis found that the effects of mental toughness, personal strength and support, peer pressure, and parent-child relationship on poor eating behavior were statistically significant (both P<0.001). (3) The results of logistic multivariate regression analysis showed that psychological toughness, strong personal strength and close parent-child relationship were the protective factors of adolescents' bad eating behavior (personal strength: OR=0.960; parent-child relationship: OR=0.949High age and increased peer pressure were risk factors for poor eating behaviors in adolescents (age: OR=25.439; peer pressure: OR=1.052). Conclusion: In a city in Guangxi, adolescents with strong psychological toughness, strong personal strength and close parent-child relationship reduce the risk of adolescents' bad eating behaviors, and high age and peer pressure increase the risk of adolescents' bad eating behaviors.
