Objective: To explore the association between waist circumference and beverage consumption behaviors among junior high school students, so as to provide a theoretical basis for improving their nutritional status. Methods: Using a multi stage cluster random sampling method, 1 611 junior high school students aged 13-15 years from Yushan, Yanshan, Yiyang, and Wannian counties in Shangrao City, Jiangxi Province, were selected for a survey in September 2021 through questionnaires and waist circumference measurements. Stratified analyses were conducted by sex, t-test and analysis of variance (ANOVA) were used to compare waist circumference across groups, and analysis of covariance (ANCOVA) was applied to examine the associations between different types of beverage consumption and waist circumference. Results: Boarding students had significantly greater average waist circumference than day students[boys:(71.86±9.24, 69.69±12.19)cm；girls:(66.53±13.30, 64.63±11.90)cm； t =2.69, 2.08, both P < 0.05 ]. Among boys, waist circumference differed significantly by vigorous physical[vigorous physical:(69.71±9.53)cm; non vigorous exercise:(71.53±12.99)cm]( t=-2.31, P <0.05). Boys waist circumference also differed significantly by consumption frequency (high and medium,low,none) of milk containing beverages[(71.83±7.40, 69.92±9.98, 72.29±13.90)cm], functional beverages[( 73.36± 11.87, 65.97±10.46, 70.71±10.55)cm] and purified water beverages[(69.36±10.87, 71.93±12.15, 71.50±10.09)cm]( F =4.06, 5.93, 4.85, all P <0.05). Girls waist circumference also differed significantly by consumption frequency (high and medium,low,none) of milk containing beverages[(68.81±5.55, 66.59±13.02, 65.36±11.69)cm, F=9.67, P <0.01]. After controlling for the confounding variables, ANCOVA results indicated that the consumption of milk containing beverages, functional beverages and Purified water beverages were significantly associated with waist circumference of boys ( F =3.79, 5.26, 5.08, all P < 0.05 ). Milk containing beverages were significantly associated with waist circumference of girls ( F=4.17, P <0.05). Conclusion The consumption frequency of milk containing beverages and functional beverages by junior high school students is positively correlated with their waist circumference.
