Daily Protein Intake and Distribution of Daily Protein Consumed Decreases Odds for Functional Disability in Older Americans
Objective: We sought to determine whether daily protein intake and protein distribution across eating occasions were associated with functional disability in a national sample of older Americans. Methods : Data from 8,070 adults aged ≥60 years from the 2007-2016 waves of the National Health and Nutrition Examination Survey were included. Protein intake and functional capacity was self-reported. A daily protein recommendation of ≥1.0 g/kg/day was …
A non-invasive assessment of skin carotenoid status through reflection spectroscopy is a feasible, reliable and potentially valid measure of fruit and vegetable consumption in a diverse community samp…
Objective To assess the feasibility, reliability and validity of reflection spectroscopy (RS) to assess skin carotenoids in a racially diverse sample. Design Study 1 was a cross-sectional study of corner store customers ( n 479) who completed the National Cancer Institute Fruit and Vegetable Screener as well as RS measures. Feasibility was assessed by examining the time it took to complete three RS measures, reliability was assessed by examining …
Agricultural Capacity to Increase the Production of Select Fruits and Vegetables in the US: A Geospatial Modeling Analysis
The capacity of US agriculture to increase the output of specific foods to accommodate increased demand is not well documented. This research uses geospatial modeling to examine the capacity of the US agricultural landbase to increase the per capita availability of an example set of nutrient-dense fruits and vegetables. These fruits and vegetables were selected based on nutrient content and an increasing trend of domestic production and consumpti…
Diet quality on meatless days: National Health and Nutrition Examination Survey (NHANES), 2007–2012
Objective To compare diet quality scores between adult non-meat eaters and meat eaters, and to compare the consumption of diet components across quintiles of diet quality. Design Cross-sectional analysis. The Healthy Eating Index-2010 (HEI-2010) and Alternative Healthy Eating Index-2010 (AHEI-2010) were used to assess mean diet quality. Differences in consumption of diet components between quintiles of diet quality were tested using post hoc Wald…
Characterizing trends in fruit and vegetable intake in the USA by self-report and by supply-and-disappearance data: 2001–2014
Objective To examine the comparability of fruit and vegetable (F&V) intake data in the USA from 2001 to 2014 between data acquired from two national data collection programmes. Design Cross-sectional analysis. Linear regression models estimated trends in daily per capita intake of total F&V. Pooled differences in intake of individual F&V ( n 109) were examined by processing form (fresh, frozen, canned, dried and juice). Setting What We Eat in Ame…
Barriers and facilitators to following the Dietary Guidelines for Americans reported by rural, Northern Plains American-Indian children
Objective The Dietary Guidelines for Americans (DGA) promote healthy dietary choices for all Americans aged 2 years and older; however, the majority of Americans do not meet recommendations. The goal of the present study was to identify both barriers and facilitators to adherence to DGA recommendations for consumption of five recommended food groups: grains (specifically whole grains), vegetables, fruits, meat/beans and milk (specifically reduced…
Barriers and Facilitators to Being Physically Active on a Rural U.S. Northern Plains American Indian Reservation
The objective of the present study was to identify barriers to and facilitators of physical activity among American Indian adults living on a rural, U.S. Northern Plains reservation using the nominal group technique (NGT). NGT is a method of data generation and interpretation that combines aspects of qualitative (free generation of responses) and quantitative (systematic ranking of responses) methodologies. Adults participated in one of two NGT s…
Retracted: Relation of parenting styles, feeding styles and feeding practices to child overweight and obesity. Direct and moderated effects
Retracted: Relation of parenting styles, feeding styles and feeding practices to child overweight and obesity. Direct and moderated effects
The purpose of this study was to evaluate the direct and interacting relations of parenting styles, feeding styles, and feeding practices to child overweight and obesity. Participants were 144 mothers and children under 6 years of age. Mothers completed questionnaires about parenting and feeding styles and feeding practices. Researchers weighed and measured mothers and children or obtained measurements from a recent health report. Feeding practic…
Who is missing the message? Targeting strategies to increase food label use among US adults
Objective To evaluate the associations between sociodemographic and psychosocial characteristics and food label (FL) use in US adults. Design Data from the 1994–1996 Continuing Survey of Food Intakes by Individuals and the Diet and Health Knowledge Survey were used. High socio-economic status (SES) was defined as >high school education and poverty–income ratio (PIR) >350 %, low SES as Setting Metropolitan statistical area-central city, -suburban,…
The declining prevalence of overweight among Russian children: Income, diet, and physical activity behavior changes
The use of external within-person variance estimates to adjust nutrient intake distributions over time and across populations
Objective To examine the utility of using external estimates of within-person variation to adjust usual nutrient intake distributions. Design Analyses of the prevalence of inadequate intake of an example nutrient by the Estimated Average Requirement (EAR) cut-point method using three different methods of statistical adjustment of the usual intake distribution of a single 24-hour recall in Russian children in 1996, using the Iowa State University …
