Psychometric evaluation of the power of food scale in a diverse college sample: Measurement invariance across gender, ethnicity, and weight status.

Psychometric evaluation of the power of food scale in a diverse college sample: Measurement invariance across gender, ethnicity, and weight status. Eat Behav. 2019 Dec;35:101336 Authors: Serier KN, Belon KE, Smith JM, Smith JE Abstract The Power of Food Scale (PFS) is an instrument designed to examine individual differences in the drive to eat for pleasure (as opposed to in response to physiological hunger) and the effect of living in an obesogenic environment. Previous research supports the validity and reliability of the PFS, however, it had yet to be validated in an ethnically diverse college sample. The purpose of the current study was to test the factor structure and measurement invariance of the PFS across gender, ethnicity, and weight status. A sample of 432 college students completed the PFS (males=113, females = 319; non-Hispanic white=181, Hispanic=251; non-overweight=302, overweight=130). Confirmatory factor analysis was used to test a second-order, 3-factor (food available, food present, food tasted) structure of the PFS in each group separately (males, females, Hispanic, non-Hispanic white, non-overweight, and overweight) and tests of measurement invariance were conducted to test the equivalency of the measure across gender, ethnicity, and weight status. Results supported the measure's original factor structure (second-order, 3-factor model) and indicated that the measure is equivalent across each of these groups, respectively. Although the ...

Authors: Güler B, Özler S, Kadıoğlu N, Özkan E, Güngören MS, Çelen Ş Abstract Our aim was to investigate whether Antimullerian Hormone (AMH), complete blood count (CBC), Homeostasis model assessment (HOMA-IR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and weight gain have any diagnostic value for the prediction of cardiovascular disease (CVD) in obese and non-obese pregnant patients. A prospective, case-control study was carried out, including 187 patients (93 obese, and 94 non-obese). CVD risk for each patient was evaluated according to the American College o...

Publication date: Available online 7 December 2019Source: Obesity Research &Clinical PracticeAuthor(s): Nicholas D. Spence, Joseph A. Skelton, Geoff D.C. BallAbstractPediatric obesity is a major public health issue. Lifestyle and behavioral interventions are the foundation of pediatric weight management; however, intervention effectiveness is compromised when families (children, youth, and/or parent[s]) discontinue care prematurely. Intervention attrition minimizes the potential health benefits derived from interventions, results in inefficient use of health services resources, and can magnify health disparities. Most ...

This study aims to determine if IER results in lower body mass index (BMI) z-score after 52 weeks in metabolically unhealthy adolescents with obesity compared with continuous energy restriction (CER).Methods/designThis is a prospective, randomised, multi-centre trial conducted in tertiary care settings, with three phases: jumpstart (weeks 0–4); intensive intervention (weeks 5–16); continued intervention and/or maintenance (weeks 17–52). During the jumpstart phase, all participants follow a very low energy diet (∼800 kcal/3350 kJ/day), then transition to their allocated intervention: IER or C...

Authors: Webster EK, Robinson LE, Wadsworth DD Abstract BACKGROUND: Activity breaks are an established way physical activity may be incorporated into the preschool day. The purpose of this study was to examine what factors influenced moderate to vigorous physical activity (MVPA) during a teacher-implemented classroom-based activity break (CBAB) in a Head Start population. METHODS: Ten-minute CBAB was conducted over 2 days in a quasi-experimental design; 99 preschoolers (mean age 3.80 [0.65] y; 49.5% male) from a convenience sample participated. Accelerometers measured MVPA, fundamental motor skill competen...

Abstract We studied dynamic thiol/disulphide homeostasis, an indicator of oxidative stress, to investigate the effects of newly initiated exercise training on sedentary obese adults. Seventeen sedentary obese adults and 15 normal-weight controls were included in the sample for this study. The obese adults were given a physical exercise training program that lasted twelve weeks. Before and after the exercise training program, blood samples were collected, and serum thiol/disulphide parameters were measured by using a novel technique. Before the start of the exercise training, it was observed that thiol/disulphide h...
