Evaluating the healthfulness of Asian American young adult dietary behaviors and its association with family structure: Disaggregated results from NHIS 2015

Background: Asian Americans (AA) young adults face a growing non-communicable disease burden linked with poor dietary behaviors. Family plays a significant role in shaping the diet of AA young adults, although little is known on the specific types of family structures most associated with different dietary behaviors. Aim: This analysis explores the changes in dietary behaviors across different AA young adult family structural characteristics. Methods: Nationwide data of 18–35-year-old self-identified Asians surveyed in the 2015 National Health Interview Survey (NHIS) was analyzed. Family structure was measured through family size, family health, and family members in one's life. The Dietary Screener Questionnaire (DSQ) measured the average intake of 10 food and nutrient groups. Published dietary guidelines were used to calculate the number of dietary recommendations met. Results: 670 AA young adults with dietary data were analyzed (26.1% Asian Indian, 26.1% Chinese, 19.3% Filipino, 28.5% other Asian). Participants had an average family size of 2.3. In weighted analyses, 19% of AA young adults met none of the examined dietary recommendations, and only 14% met 3–4 guidelines. Living with a child was associated meeting more dietary recommendations (adjusted odds ratio [AOR]: 1.22; 95%CI: 1.05, 1.42). The adjusted association between living with an older adult and lower odds of meeting dietary recommendations approached significance (AOR: 0.70; 95%CI: 0.49, 1.00). Conclusions: Findings revealed the important role of children and older adults in influencing the diet of AA young adults. Further mixed-methods research to disentangle mechanisms behind the influence of family structure on diet is warranted.
