Thirteen-Year Trends in Dietary Patterns among Japanese Adults in the National Health and Nutrition Survey 2003?2015: Continuous Westernization of the Japanese Diet.

ABSTRACT: We examined 13-year trends in dietary patterns, using data from the National Health and Nutrition Survey, Japan 2003?2015. In repeated, independent cross-sectional studies, dietary intake was assessed with a one-day weighed dietary record in 88,527 Japanese adults aged ?20 years. Using principal component analysis based on the daily consumption of 31 food groups, we identified three dietary patterns, the "plant food and fish", "bread and dairy", and "animal food and oil" patterns. In the whole sample, the "plant food and fish" pattern score decreased while the "bread and dairy" and "animal food and oil" pattern scores increased. The decreasing trends in the "plant food and fish" pattern were observed in all subgroups considered. The increasing trends in the "bread and dairy" pattern were similar across sexes and by current smoking status. However, in terms of age, occupation, and weight status, the increasing trends were only evident in particular subgroups (i.e., age 50?64 and ?65 years; security/transportation/labor occupation and nonworker; and normal weight and overweight participants). For the "animal food and oil" pattern, the increasing trends were observed in all subgroups, except for the youngest age group (20?34 years old). This study suggests continuous Westernization of the Japanese diet.

We examined 13-year trends in dietary patterns, using data from the National Health and Nutrition Survey, Japan 2003⁻2015. In repeated, independent cross-sectional studies, dietary intake was assessed with a one-day weighed dietary record in 88,527 Japanese adults aged ≥20 years. Using principal component analysis based on the daily consumption of 31 food groups, we identified three dietary patterns, the "plant food and fish", "bread and dairy", and "animal food and oil" patterns.

Project description:Background/objectivesFood insecurity has emerged as a critical health issue for older adults. Food insecurity has been shown to disrupt healthy eating patterns, but these associations have not been widely studied among older adults. The objectives of the present study were to: (1) examine national trends in food insecurity across a 10-year period, and (2) evaluate the associations between food insecurity and multiple diet quality indices in a recent and nationally representative sample of adults aged 60 or older.DesignCross-sectional analysis of the 2007-2016 National Health and Nutrition Examination Surveys.SettingNationally representative sample of the United States.ParticipantsThe analytic sample was comprised of 5,097 adults aged 60 or older, with household incomes at or below 300% of the federal poverty level.MeasurementsHousehold food security was measured using the 18-item US Household Food Security Survey Module. Diet was assessed using two 24-hour dietary recalls. Multivariate linear and logistic regression models examined the associations between household food security and three evidence-based diet quality indices, adjusting for sociodemographic and health characteristics.ResultsAcross the 10-year period, food insecurity increased significantly from 5.5% to 12.4% among older adults; this increase was more pronounced among lower-income older adults. From the linear regression models, food insecurity was associated with lower scores on the Healthy Eating Index (β = -1.90, 95% confidence interval (CI) = -3.70, -0.09), the Alternate Healthy Eating Index-2010 (β = -1.47, 95% CI = -2.51, -0.44), and the Mediterranean Diet Score (β = -0.54, 95% CI = -1.06, -0.01) after multivariate adjustment. Further adjustment for the presence of chronic medical conditions did not attenuate these results.ConclusionFood insecurity is associated with lower overall diet quality among older adults, supporting the need for clinical efforts to identify those at risk of food insecurity and public health efforts to alleviate food insecurity and promote healthy eating behaviors among older adults.
