The diet quality of US adults is poor and cross-sectional analyses suggest self-perception of healthful dietary intake may be overestimated. This analysis assessed the concordance between calculated and perceived diet quality and changes in diet quality among adults seeking weight loss and enrolled in a 12-month randomized behavioral trial. Healthy Eating Index-2015 diet quality (HEI) was calculated from self-administered 24-hour recalls. Perceived diet quality (PDQ) was measured on a 100-point scale. Higher scores indicate better diet quality. Concordance was assessed using the concordance correlation coefficient and Bland-Altman plots. The one hundred and five participants with complete dietary data were mostly female and white. There was good agreement between HEI and PDQ scores at 12 months for less than a third of participants. Most of the disagreement arose from PDQ scores being higher than HEI scores. Even fewer participants had good agreement between HEI changes and PDQ changes. Participants perceived greater improvement in diet quality than indicated by HEI score changes. Concordance was low at 12 months and for change in diet quality. Despite the diet quality of adults seeking weight loss being suboptimal and not improving, many perceived their diet quality and diet quality improvements as better than calculated. Future studies might explore the effect of misperceptions on weight loss outcomes. [ABSTRACT FROM AUTHOR]

Background: This study examined associations between physical activity (recreational, nonrecreational) and sleep duration among a nationally representative diverse sample of U.S. adults. Methods: We used cross-sectional data from 9,205 National Health and Nutrition Examination Survey 2007 to 2012 participants aged 20 to 65 years who identified as White, Black, or Hispanic. Activity (ie, recreation, occupation, and transportation activity) was categorized into quartiles. Sleep duration was categorized as short (≤6 hours/night) or normal (>6 to ≤9 hours/night). Logistic regression was used to estimate associations of activity with sleep duration. Results: Recommended levels of recreation activity and moderate levels of transportation activity were associated with normal sleep duration [Odds Ratio (OR): = 1.33, 95% Confidence Interval (CI) = 1.08, 1.65; OR = 1.28, 95% CI = 1.02, 1.62, respectively]. High occupation physical activity was associated with shorter sleep duration (OR = 0.59, 95% CI = 0.49, 0.71). Differences were observed by race/ethnicity in associations of recreation and occupation activity with sleep duration. Conclusions: White individuals who engaged in some recreation activity, relative to being inactive, had more favorable sleep duration; whereas, high levels of occupation activity were associated with worse sleep duration among White and Black individuals. Physical activity was not associated with sleep duration among Hispanics. [ABSTRACT FROM AUTHOR]

Introduction: The American Heart Association created "Life's Simple Seven" metrics to estimate progress toward improving US cardiovascular health in a standardized manner. Given the widespread use of federally funded Diabetes Prevention Program (DPP)-based lifestyle interventions such as the Group Lifestyle Balance (DPP-GLB), evaluation of change in health metrics within such a program is of national interest. This study examined change in cardiovascular health metric scores during the course of a yearlong DPP-GLB intervention. Methods: Data were combined from 2 similar randomized trials offering a community based DPP-GLB lifestyle intervention to overweight/obese individuals with prediabetes and/or metabolic syndrome. Pre/post lifestyle intervention participation changes in 5 of the 7 cardiovascular health metrics were examined at 6 and 12 months (BMI, blood pressure, total cholesterol, fasting plasma glucose, physical activity). Smoking was rare and diet was not measured. Results: Among 305 participants with complete data (81.8% of 373 eligible adults), significant improvements were demonstrated in all 5 risk factors measured continuously at 6 and 12 months. There were significant positive shifts in the "ideal" and "total" metric scores at both time points. Also noted were beneficial shifts in the proportion of participants across categories for BMI, activity, and blood pressure. Conclusion: AHA-metrics could have clinical utility in estimating an individual's cardiovascular health status and in capturing improvement in cardiometabolic/behavioral risk factors resulting from participation in a community-based translation of the DPP lifestyle intervention.

Purpose: To assess adherence to the 2015-2020 Dietary Guidelines for Americans and 2018 Physical Activity Guidelines, and identify sociodemographic predictors of adherence among children.Design: Cross sectional.Setting: Colorado, United States.Participants: Children aged 5 (n = 482).Measures: Sex, race/ethnicity, maternal education, maternal employment, maternal subjective social status and household income were assessed via questionnaires. Diet was assessed via 2 interviewer-administered 24-hour dietary recalls. Physical activity was objectively-measured with accelerometry for 7 days. Adherence was defined as a Healthy Eating Index-2015 score of ≥70 and/or ≥6 hours/day of light, moderate and vigorous activity.Analysis: For each predictor, logistic regression was used to estimate odds ratios for adherence to the diet guidelines only, the activity guidelines only or both guidelines.Results: In the full sample, 29% of children were non-adherent to both guidelines, 6% adhered to the dietary guidelines only, 50% adhered to the activity guidelines only and 14% adhered to both. Girls had a 41% lower odds of adhering to the physical activity guidelines than boys (p = 0.01), after adjustment for race/ethnicity, household income and maternal education level, perceived social status and employment status.Conclusion: Efforts to improve the health of young children should promote adherence to the Dietary Guidelines for Americans among all children. Targeted interventions that increase physical activity among girls may help to mitigate health disparities. [ABSTRACT FROM AUTHOR]

Background: Narrative medicine is a powerful approach for strengthening clinicians' therapeutic alliances with patients and helping them understand others' perspectives by giving patients a voice. MyPaTH Story Booth is a cross-sectional observational study that uses narrative medicine concepts to allow community participants to share their health and healthcare-related experiences through relatively unstructured interviews (i.e., stories). The archive forms a qualitative research 'commons' where researchers can learn about patient and caregiver perspectives and tailor research goals to better address community needs. Brief surveys allow storytellers to classify their stories so that the archive is searchable., Methods: This study assessed sensitivity, specificity, positive predictive and negative predictive values of self-reported surveys for categorizing 83 stories, compared with a 'gold standard' (most commonly accepted method for interpreting narratives) of qualitative coding. Stories were classified as either having or not having each of 38 different classifications based on US National Library of Medicine (NLM) Health Topics (Type of disorder or condition and Part of the body discussed) or developed with stakeholder input (Type of health/healthcare experience)., Results: Survey data assessing 'Part of the body discussed' and 'Type of disorder or condition' typically was highly sensitive (64%-95%) and specific (73%-99%) suggesting high adequacy of surveys in identifying stories. Questions focused on 'Type of health/healthcare experience' showed inconsistent and relatively lower sensitivities (48%-93%) and specificities (30%-79%) suggesting lower adequacy of surveys in identifying stories., Conclusion: Survey items based on NLM Health Topics allowed people to categorize their health narratives into relevant, searchable topics making the database more accessible., (© 2023 John Wiley & Sons Ltd.)

Purpose: The purpose of this study was to examine how maintenance session attendance and 6-month weight loss (WL) goal achievement impacted 12-month 5% WL success in older adults participating in a community-based Diabetes Prevention Program (DPP) lifestyle intervention., Methods: Data were combined from 2 community trials that delivered the 12-month DPP-based Group Lifestyle Balance (GLB) to overweight/obese adults (mean age = 62 years, 76% women) with prediabetes and/or metabolic syndrome. Included participants (n = 238) attended ≥4 core sessions (months 0-6) and had complete data on maintenance attendance (≥4 of 6 sessions during months 7-12) and 6- and 12-month WL (5% WL goal, yes/no). Multivariate logistic regression was used to estimate the odds of 12-month 5% WL associated with maintenance attendance and 6-month WL. Associations between age (Medicare-eligible ≥65 vs <65 years) and WL and attendance were examined., Results: Both attending ≥4 maintenance sessions and meeting the 6-month 5% WL goal increased the odds of meeting the 12-month 5% WL goal. For those not meeting the 6-month WL goal, maintenance session attendance did not improve odds of 12-month WL success. Medicare-eligible adults ≥65 years were more likely to meet the 12-month WL goal (odds ratio = 3.03, 95% CI, 1.58-5.81) versus <65 years., Conclusions: The results of this study provide important information regarding participant attendance and WL for providers offering DPP-based lifestyle intervention programs across the country who are seeking Medicare reimbursement. Understanding Medicare reimbursement-defined success will allow these providers to focus on and develop strategies to enhance program effectiveness and sustainability.

Introduction: Male youth in the United States commonly participate in gridiron (American) football. There are little data substantiating current popular opinion that it is associated with knee pain or osteoarthritis (OA) later in life. We aimed to evaluate the relationship of football with these outcomes in the Osteoarthritis Initiative (OAI)., Methods: This is a study of male OAI participants with knee x-ray readings, symptom assessments, and completed surveys on lifetime physical activity. The OAI is a multicenter, observational cohort recruited from the community not based on football participation status. A history of exposure to American football was ascertained via self-report. Knee radiographs were scored for Kellgren-Lawrence grade (0-4). Radiographic OA (ROA) was defined as Kellgren-Lawrence ≥ 2 in at least one knee. Frequent knee pain meant at least one knee with frequent knee pain. Symptomatic ROA required at least one knee with both ROA and frequent knee pain., Results: A total of 1166 men had a mean age of 63.7 (SD, 9.2) yr and body mass index of 28.6 (SD, 4.2) kg·m. Thirty-one percent (365/1166) played football at some point in their lives, 95% of whom participated from ages 12 to 18 yr. The ORs for symptomatic ROA from the lowest to highest football participation were 1.2, 1.5, and 2.2, respectively (P for trend = 0.004). Findings were similar for football from ages 12 to 18 yr and for outcomes of knee pain and ROA., Conclusion: This is the first large epidemiologic study to suggest that football participation, including in the teen years, may be detrimental toward knee health. Prospective studies evaluating football players are warranted.

Background: Metabolic syndrome (MetS) is a global health problem. Physical activity (PA) is a known modifiable risk factor for MetS and individual MetS components. However, the role of PA could differ between sub-populations due to differences in the variability of PA and other MetS risk factors. To examine these differences, multi-country studies with standardized outcome measurement methods across cohorts are needed., Methods: Cross-sectional PA levels (total and domain specific) in healthy middle-aged (44-56 years) men in the Risk Factor Assessment among Japanese and U.S. Men in the Post-World War II Birth Cohort (ERA-JUMP) Study ( n  = 730; American: n  = 417; Japanese: n  = 313; from population-representative samples in Pittsburgh, Pennsylvania, USA, and Kusatsu, Shiga, Japan) were compared. The relationships between PA levels and MetS (overall and specific components) in/across the American and Japanese sub-cohorts (adjusting for age, smoking, and alcohol consumption) were also assessed using the same instruments (pedometer and validated questionnaire) to measure PA in both cohorts., Results: A total of 510 individuals provided complete data on PA (American: n  = 265; Japanese: n  = 245). The American cohort had significantly lower mean ± SD steps/day (7878 ± 3399 steps/day) vs. the Japanese cohort (9055 ± 3797 steps/day) ( p < 0.001) but had significantly higher self-reported moderate-vigorous leisure PA (American: 15.9 (7.4-30.3) metabolic task equivalent hours per week (MET-h/week) vs. Japanese: 4.0 (0-11.3) MET-h/week, p < 0.0001). In both sub-cohorts, each 1000 steps/day increase was associated with lower odds of having MetS (American: OR = 0.90, 95%CI: 0.83-0.98; Japanese: OR = 0.87, 95%CI: 0.79-0.95) and the individual MetS component of high waist circumference (American: OR = 0.86, 95%CI: 0.79-0.94; Japanese: OR = 0.87, 95%CI: 0.80-0.95). In the American cohort only, higher self-reported leisure PA (Met-h/week) was associated with lower odds of MetS and high waist circumference (OR = 0.98, 95%CI: 0.97-0.99 for MetS and waist circumference, respectively)., Conclusion: Higher total step counts/day had an important protective effect on MetS prevalence in both the Japanese and American cohorts, despite differences in PA levels and other MetS risk factors. The effect of steps/day (across all intensity levels) was much greater than domain-specific moderate-vigorous PA captured by questionnaire, suggesting the need for measurement tools that can best capture total movement when examining the effects of PA on MetS development., (© 2019 Published by Elsevier B.V. on behalf of Shanghai University of Sport.)
