Outline
To develop a comprehensive index for evaluating the beverage intake quality of Chinese children and assess its reliability and validity.
Using data on commercially available children’s beverages in China collected through both online and offline channels, beverage scores were calculated for different beverage categories. Based on these scores and relevant domestic and international recommendations, CCHBI was established. Leveraging publicly available data from the China Health and Nutrition Survey and referencing the validity and reliability evaluation methods of the Healthy Beverage Index for American Children, the validity and reliability of CHNS were assessed in terms of construct validity, discriminant validity, and internal consistency.
The CCHBI comprised four assessment dimensions—beverages, added sugars, water intake, and knowledge/attitudes—with 14 indicators, yielding a total score range of -77 to 19 points. Children with higher CCHBI scores exhibited water consumption more aligned with recommended standards and tended to choose healthier beverages such as 100% pure fruit juice. The index identified five distinct beverage consumption patterns, reflecting diversity in intake. The CCHBI demonstrated strong discriminant validity, differentiating beverage quality across sociodemographic factors such as residential location and maternal education level (Ps<0.05). Children with poor beverage intake quality exhibited an increased risk of overweight/obesity, confirming criterion validity. The standardized and non-standardized Cronbach α coefficients were 0.63 and 0.67, respectively, indicating acceptable internal consistency.
The CCHBI effectively reflects beverage intake quality and consumption habits among Chinese children, with satisfactory reliability and validity.
