Sex differences in sociodemographic and lifestyle factors associated with diet quality in a multiethnic population.

ABSTRACT: OBJECTIVES:The purpose of this study was to examine associations of sociodemographic and lifestyle factors with diet quality in a multiethnic population. METHODS:The analysis included 160?353 African American, Native Hawaiian, Japanese American, Latino, and non-Hispanic white participants aged 45 to 75 y who entered the Multiethnic Cohort study by completing a comprehensive questionnaire in 1993 to 1996 and did not report cancer or heart disease. Diet quality was assessed using four diet quality indexes (DQIs): the Healthy Eating Index 2010, the Alternative Healthy Eating Index 2010, the alternate Mediterranean Diet, and the Dietary Approaches to Stop Hypertension. RESULTS:For three DQIs, the Healthy Eating Index 2010, Alternative Healthy Eating Index 2010, and Dietary Approaches to Stop Hypertension, mean scores were significantly higher in women than men, whereas the mean score of the alternate Mediterranean Diet was significantly higher in men than women. In both men and women, older age, higher education, being physically active, and multivitamin use were associated with scores above the median of DQIs, whereas overweight/obesity, current smoking, and heavy alcohol consumption (?2 drinks/d) were associated with scores less than the median of DQIs. Race/ethnicity had inconsistent associations according to the DQIs. Being widowed, being a previous smoker, and having a low body mass index (<20 kg/m2) were associated with scores less than the median of DQIs in men but not in women. CONCLUSIONS:Diet quality was associated with sociodemographic and lifestyle characteristics in men and women. The associations with several factors, such as marital status, body mass index, and smoking status, differed by sex. These findings may help to identify at-risk populations for nutritional screening and to develop nutritional intervention strategies and educational materials.

Project description:BackgroundTrends in diet quality among US adults indicate a steady improvement, but data on longitudinal individual-level changes in diet quality are still limited.ObjectiveWe examined changes in diet quality over 10 y and sought to determine whether baseline sociodemographic and lifestyle factors predicted the changes in a multiethnic population.MethodsData were from 63,255 African American, Native Hawaiian, Japanese American, Latino, and white men and women (45-75 y old at baseline) in the Multiethnic Cohort, who completed a quantitative food frequency questionnaire at baseline (1993-1996) and 10-y follow-up (2003-2007) and had no prevalent cancer or heart disease at either survey. Overall diet quality was measured by use of the Healthy Eating Index-2015 (HEI-2015), the Alternative Healthy Eating Index-2010 (AHEI-2010), the alternate Mediterranean Diet score, and the Dietary Approaches to Stop Hypertension (DASH) score. We used a general linear model with adjustment for covariates to compare diet quality changes by baseline characteristics in men and women separately.ResultsOverall diet quality improved over 10 y by 3.2 points in men and 2.9 in women assessed using the HEI-2015, although scores for some components worsened (saturated and trans fats, indicating increased intake) or remained unchanged at a low quality level (whole grains, dairy, and sodium). In multivariable models where changes in HEI-2015, AHEI-2010, and DASH were harmonized to a 100-point score, greater increases in scores in both men and women were found for Japanese American ethnicity (increase by 0.5-4.7 in the 3 scores, P < 0.03), higher education (by 0.5-1.5, P ≤ 0.001), normal weight (BMI 18.5 to <25, by 0.6-2.5, P ≤ 0.01), nonsmoking (by 1.5-2.7, P < 0.001), higher moderate/vigorous physical activity level (by 0.3-0.8, P ≤ 0.04), and multivitamin use (by 0.4-0.7, P < 0.001) at baseline.ConclusionsSociodemographic and lifestyle factors, closely associated with diet quality, also predicted subsequent changes in diet quality over time in this multiethnic population.

Project description:BACKGROUND:Few population-based studies have assessed dietary behaviors in the rural multiethnic population of Northern Norway. The present study determined dietary patterns and investigated their association with Sami ethnicity, sociodemographic factors, and lifestyle factors in a multiethnic population in rural Northern Norway. METHODS:This cross-sectional study included 4504 participants of the SAMINOR 2 Clinical Survey (2012-2014) aged 40-69?years. All participants completed a lifestyle and food frequency questionnaire. Dietary patterns were determined using principal component analysis. Associations between food patterns and ethnicity, sociodemographic factors, and lifestyle factors were examined by multiple linear regression. RESULTS:Six dietary patterns were identified that accounted for 28% of the variability in food intake in the study sample: 'processed meat/westernized', 'fish/traditional', 'fruit/vegetables', 'reindeer/traditional', 'bread and sandwich spreads', and 'sweets and bakery goods'. The 'reindeer/traditional' pattern was most common among the inland Sami population. The 'fish/traditional' pattern was most common among costal multiethnic Sami and least common among inland Sami and among women independent of ethnicity. The 'fish/traditional' pattern was also positively associated with older age, high education level, small household size, and smoking. Adherence to the 'processed meat/westernized' pattern was lower among inland Sami than inland/coastal non-Sami; no ethnic differences in adherence to this pattern were found between costal multiethnic Sami and inland/coastal non-Sami. Unhealthy lifestyle factors, like low physical activity level and smoking, and younger age were mainly associated with the 'processed meat/westernized' pattern, whereas socioeconomic factors like low education, low gross annual household income, and large household size were related to the 'sweets and bakery goods' pattern. Male gender, low education level, and smoking were associated with the 'bread and sandwich spreads' pattern. The 'fruit/vegetables' pattern was characterized by healthy dietary choices and a health-conscious lifestyle, and was more common in women with a high education level and income. CONCLUSIONS:Adherence to the six identified dietary patterns was characterized by different sociodemographic and lifestyle factors. Ethnicity, in combination with geographical region of residence, was associated with dietary behaviors. This study provides knowledge that will be useful in future studies on dietary patterns related to chronic diseases in the rural population of Northern Norway.
