Characteristics associated with fruit and vegetable consumption in mid aged and older Chinese men and women: a cross-sectional analysis of the first wave of WHO SAGE China.

Adequate fruit and vegetable consumption is essential for healthy ageing and prevention and management of chronic disease. This study aimed to examine characteristics associated with fruit and vegetable consumption in Chinese men and women aged 50 years and over. Data from the first wave of the Chinese cohort (2008-2010) of the WHO's Study on global AGEing and adult health (SAGE) survey was used. Fruit and vegetable consumption was assessed by self-reported typical consumption in serves/day. Characteristics examined were age, education, financial security, home ownership, marital status, social cohesion and rural location. Associations with fruit and vegetable consumption were assessed using multiple linear regression adjusted for confounders and stratified by sex. Overall, women consumed more serves of fruit per day than men (mean (standard deviation): 2·6 (2·2) and 2·2 (2·1) serves/day, respectively) whereas men consumed more serves of vegetables than women (7·2 (4·0) and 6·7 (3·7)). Lower fruit consumption was associated with lower education, lower social participation, income insecurity, renting, being un-partnered and rural residency in men and women, as well as older age in women. Lower vegetable consumption was associated with older age, lower education and urban residency in men and women and lower social participation in men and being unpartnered in women. This study has identified characteristics associated with fruit and vegetable intake in a sample of mid aged and older Chinese men and women. Further research on the interrelationships between these characteristics and fruit and vegetable intake as well as longitudinal relationships is warranted.
