Validity and reliability of the semi-quantitative self-report Home Food Availability Inventory Checklist (HFAI-C) in White and South Asian populations.

Despite interest in the importance of the home food environment and its potential influence on children's diets and social norms, there remain few self-report checklist methods that have been validated against the gold standard of researcher-conducted inventories. This study aimed to assess the criterion validity and reliability of the 'Home Food Availability Inventory Checklist' (HFAI-C), a 39-item checklist including categories of fruit, vegetables, snacks and drinks.The HFAI-C was completed by 97 participants of White and Pakistani origin in the UK. Validity was determined by comparing participant-reported HFAI-C responses to data from researcher observations of home food availability using PABAK and weighted kappa statistics. The validity of measuring the amount of items (in addition to presence/absence) available was also determined. Test-retest reliability compared repeated administrations of the HFAI-C using intra-class correlation coefficients.Validity and reliability was fair to moderate overall. For validity, the average category-level PABAK ranged from 0.31 (95 % CI: 0.25, 0.37) for vegetables to 0.44 (95 % CI: 0.40, 0.49) for fruits. Assessment of the presence/absence of items demonstrated higher validity compared to quantity measurements. Reliability was increased when the HFAI-C was repeated close to the time of the first administration. For example, ICCs for reliability of the measurement of fruits were 0.52 (95 %CI: 0.47, 0.56) if re-administered within 5 months, 0.58 (95 % CI: 0.51, 0.64) within 30 days and 0.97 (95 %CI: 0.94, 1.00) if re-administered on the same day.Overall, the HFAI-C demonstrated fair to moderate validity and reliability in a population of White and South Asian participants. This evaluation is consistent with previous work on other checklists in less diverse, more affluent populations. Our research supports the use of the HFAI-C as a useful, albeit imperfect, representation of researcher-conducted inventories. The feasibility of collecting information using the HFAI-C in large, multi-ethnic samples can facilitate examination of home food availability in relation to exposures such as ethnicity and outcomes including behavioural, social and health outcomes. Future work using the HFAI-C could provide important insights into a modifiable influence with potential to impact health

Driven to Support: Individual- and County-Level Factors Associated With Public Support for Active Transportation Policies

Purpose: To assess predictors of stated support for policies promoting physically active transportation. Design: Cross-sectional. Setting: US counties selected on county-level physical activity and obesity health status. Participants: Participants completing random-digit dialed telephone survey (n = 906). Measures: Survey measures assessed stated support for 5 policies to promote physically active transportation, access to active transportation facilities, and time spent in a car. County-level estimates included household car dependence and funding for bicycle–pedestrian projects. Analysis: Multivariable generalized linear mixed models using binary distribution and logit link, accounting for clustering within county. Results: Respondents supported policies for accommodating bicyclists and pedestrians through street improvements (89%), school active transportation programs (75%), employer-funded active commuting incentives (67%), and allocation of public funding (68%) and tax support (56%) for building and maintaining public transit. Residents spending >2 h/d (vs $1.6 million in bicycle and pedestrian improvements expressed greater support for funding (OR: 1.71; CI: 1.04-2.83) and tax increases (OR: 1.73; CI: 1.08-2.75) for transit improvements compared to those with lower prior investments ($1.6 M), public transit is nearby, and respondents drive >2 h/d

Association between television viewing and the risk of metabolic syndrome in a community-based population

<p>Abstract</p> <p>Background</p> <p>As a result of metabolic syndrome becoming an important issue during recent decades, many studies have explored the risk factors contributing to its development. However, less attention has been paid to the risk associated with sedentary behavior, especially television viewing. This study examined the association between television viewing time and the risk of having metabolic syndrome in a population of Taiwanese subjects.</p> <p>Methods</p> <p>This community-based cross-sectional study included 2,353 subjects (1,144 men and 1,209 women) aged 40 and over from October, 2004 to September, 2005. Information about the time spent watching TV was obtained using a self-administered questionnaire. The definition of metabolic syndrome was according to the Third Report of the National Cholesterol Education Program's Adult Treatment Panel modified for Asians.</p> <p>Results</p> <p>Compared to subjects who viewed TV < 14 hr/week, those who viewed TV > 20 hr/week had a 1.50-fold (95% confidence intervals (CI): 1.10, 2.03) risk for men and a 1.93-fold (95% CI: 1.37, 2.71) risk for women of having metabolic syndrome, after adjusting for physical activity and other covariates. Stratifying by the three categories of total activity levels, TV viewing time > 20 hr/week was found to still hold a significant risk for having metabolic syndrome in the lowest of the three categories of total activity level for men and in all three categories of total activity level for women.</p> <p>Conclusion</p> <p>The findings suggest that TV viewing is an independent risk factor associated with metabolic syndrome in Taiwanese people.</p

Overweight and obesity in relation to cardiovascular disease risk factors among medical students in Crete, Greece

BACKGROUND: Recent data indicate increasing rates of adult obesity and mortality from cardiovascular disease (CVD) in Greece. No data, however, are available on prevalence of overweight and obesity in relation to CVD risk factors among young adults in Greece. METHODS: A total of 989 third-year medical students (527 men, 462 women), aged 22 ± 2 years, were recruited from the University of Crete during the period 1989–2001. Anthropometric measures and blood chemistries were obtained. The relationships between obesity indices (body mass index [BMI], waist circumference [WC], waist-to-hip ratio [WHpR], waist-to-height ratio [WHtR]) and CVD risk factor variables (blood pressure, glucose, serum lipoproteins) were investigated. RESULTS: Approximately 40% of men and 23% of women had BMI ≥ 25.0 kg/m(2). Central obesity was found in 33.4% (average percentage corresponding to WC ≥ 90 cm, WHpR ≥ 0.9 and WHtR ≥ 50.0) of male and 21.7% (using WC ≥ 80 cm, WHpR ≥ 0.8, WHtR ≥ 50.0) of female students. Subjects above the obesity indices cut-offs had significantly higher values of CVD risk factor variables. BMI was the strongest predictor of hypertension. WHtR in men and WC in women were the most important indicators of dyslipidaemia. CONCLUSION: A substantial proportion of Greek medical students were overweight or obese, obesity status being related to the presence of hypertension and dyslipidaemia. Simple anthropometric indices can be used to identify these CVD risk factors. Our results underscore the need to implement health promotion programmes and perform large-scale epidemiological studies within the general Greek young adult population

Effect of mindfulness and yoga on quality of life for elementary school students and teachers: results of a randomized controlled school-based study

Alessandra N Bazzano,1 Christopher E Anderson,2 Chelsea Hylton,3 Jeanette Gustat2 1Department of Global Community Health and Behavioral Sciences, Tulane University School of Public Health and Tropical Medicine, New Orleans, LA, USA; 2Department of Epidemiology, Tulane University School of Public Health and Tropical Medicine, New Orleans, LA, USA; 3Project Peaceful Warriors, New Orleans, LA, USA Objective: To assess the impact of a yoga curriculum in an elementary school on student quality of life, and to assess teacher and staff perception of potential barriers to, and benefits of, introducing yoga and mindfulness into the classroom.Methods: A randomized controlled trial was utilized to assess the impact of a brief intervention on third-grade students who screened positive for symptoms of anxiety. Students were randomized to an intervention group of 20 students receiving small-group yoga/mindfulness activities for 8 weeks between October 2016 and February 2017, and a control group of 32 students receiving care as usual. The Brief Multidimensional Students&rsquo; Life Satisfaction Scale-Peabody Treatment Progress Battery and the Pediatric Quality of Life Inventory (PedsQL) served as outcomes. Teachers were invited to participate in two professional development sessions about introducing yoga and mindfulness into the classroom, and completed a survey following each of the sessions.Results: In generalized estimating equation models adjusted for time, the yoga-based intervention was associated with a 14.17 unit increase in student emotional PedsQL (p-value 0.001) and a 7.43 unit increase in psychosocial PedsQL (p-value 0.01). Results were not attenuated by adjustment. Teachers and staff reported using yoga more frequently in the classroom following the second of two professional development sessions (p-value &lt;0.05). Perceived barriers to introducing yoga to the classroom were similar at two data collection time points, while perceived benefits remained high.Conclusion: The intervention was associated with a significant improvement in emotional and psychosocial quality of life in the intervention group when compared to the control group, suggesting that yoga/mindfulness interventions may improve symptoms of anxiety among students. Yoga/mindfulness activities may facilitate stress management among elementary school students and may be added as a complement to social and emotional learning activities.

Physical distancing [is not equal to] physical inactivity

During this time of global health crisis, physical distancing, along with mask wearing, has emerged as the sine qua non social practice to protect ourselves and others from COVID-19. But as physical distancing ensues and all eyes remain fixed on the novel coronavirus, another, albeit careworn, pandemic rages on. Physical inactivity, the world\u27s fourth leading cause of death, may indeed be exacerbated by physical distancing measures, such as sheltering at home and closing or limiting access to recreation and exercise facilities. The purpose of this paper is to urge public health and medical professionals not to forget the importance of physical activity to whole-person health, recognize the importance of physical activity as a potential COVID-19 mitigation strategy and to serve as advocates for promoting active lifestyles. It is imperative that the national call for physical distancing not be interpreted as a call for physical inactivity
