Pre-post intervention exploring cognitive function and relationships with weight loss, intervention adherence and dropout.

ABSTRACT:

Objective

To evaluate the association between baseline cognitive function, intervention dropout, adherence and 3-month weight loss (WL) when controlling for confounding demographic variables.

Methods

107 (Mage = 40.9 yrs.), BMI in the overweight and obese range (BMI = 35.6 kg/m²), men (N = 17) and women (N = 90) completed a 3-month WL intervention. Participants attended weekly behavioral sessions, comply with a reduced calorie diet, and complete 100 min of physical activity (PA)/wk. Cognitive function tasks at baseline included Flanker (attention), Stroop (executive control) and working memory, demographics, body weight and cardiovascular fitness were assessed at baseline. Session attendance, adherence to PA and diet were recorded weekly.

Results

Baseline attention was positively correlated with age (p < .05), education (p < .05), attendance (p < .05), diet (p < .05) and PA (p < .05). Baseline executive control (p < .05) and working memory (p < .05) were each associated with % WL. Baseline executive control (p < .01) and working memory (p < .001) were also each associated with education. ANOVA indicated that baseline attention (p < .01) was associated with WL, specifically for comparing those who achieved 5-10% WL (p < .01) and those who achieved greater than 10% WL (p < .01) to those who dropped.

Significance

Results suggest that stronger baseline attention is associated with completion of a 3-mo. WL intervention. Executive control and working memory are associated with amount of WL achieved.

Project description:Background/objectivesTo examine the association between indices of sleep quantity and quality with dietary adherence, physical activity adherence, and weight loss during a behavioral weight loss intervention.MethodsAdults (n = 156) with overweight and obesity (40 ± 9 years, 84% female, BMI: 34.4 ± 4.2 kg/m2) participated in an 18-month behavioral weight loss intervention which prescribed a reduced calorie diet (1200-1800 kcal/d) and increased physical activity (300 min/wk). Body weight, indices of sleep (SenseWear armband; SWA), energy intake (EI, 3-day food records), and moderate-to-vigorous physical activity (SWA) were measured at baseline, 6, 12, and 18 months. Linear mixed effects models examined the association between sleep and weight change over time. Additional models were adjusted for covariates including age, BMI, sex, race, ethnicity, study completion, randomization, EI, and physical activity. Secondary analyses examined the association between sleep and adherence to diet and physical activity recommendations.ResultsMean weight loss was 7.7 ± 5.4, 8.4 ± 7.9, and 7.1 ± 9.0 kg at 6, 12, and 18 months, respectively. Lower sleep efficiency, higher wake after sleep onset (WASO), more awakenings, and higher sleep onset latency (SOL) were significantly associated with attenuated weight loss (p < 0.05). Lower sleep efficiency, more awakenings, and higher SOL remained significantly associated with blunted weight loss after adjustment for covariates (p < 0.05). Later waketime, longer time in bed, longer sleep duration, higher WASO, more awakenings, and higher SOL were associated with lower odds of achieving ≥300 min/wk of moderate-to-vigorous physical activity, adjusted for covariates (FDR p < 0.05).ConclusionsFuture studies should evaluate whether incorporating strategies to improve sleep health within a behavioral weight loss intervention leads to improved adherence to diet and physical activity recommendations and enhanced weight loss.Clinical trials identifierNCT01985568.

Project description:BackgroundThe LIFE study was a randomized controlled trial assessing the impact of a self-acupressure intervention, Tapas Acupressure Technique® (TAT®), on weight-loss maintenance. The primary analysis showed no significant difference between TAT and social support (SS) for weight-loss maintenance, while exploratory post hoc tests suggested that, among participants with highest initial weight-loss, those in the TAT condition regained less weight than those in the SS condition.ObjectiveThe aim of the current study was to assess adherence to, and satisfaction with, the experimental self-acupressure intervention in the LIFE weight loss maintenance trial.DesignThis was a secondary analysis of adherence and satisfaction patterns in a large randomized controlled trial.SettingThe study was conducted at a prominent health maintenance organization in the Pacific Northwest.SubjectsThis study involved 142 obese participants who had lost >10 pounds in a conventional weight-loss program and who were randomized to the experimental acupressure intervention.InterventionsThe experimental intervention (n=142) arm consisted of instruction and application of a self-acupressure intervention, the Tapas Acupressure Technique® (TAT®).Outcome measuresThe outcome sought was self-reported satisfaction and frequency of TAT practice.ResultsSixty-six percent of TAT participants attended at least 6 of 8 intervention sessions. More than 80% of participants reported practicing TAT at home, on average, at least 2 days per week. Sixty two percent reported practicing <10 minutes per session, while 27% reported practicing 10-20 minutes per session. Higher satisfaction scores were significantly correlated with less weight regain (p=0.001). Frequency of TAT practice was not significantly associated with changes in weight, stress, insomnia, depression, or quality of life.ConclusionsThese data suggest moderate acceptance of, and adherence to, the TAT intervention. Further research is required to identify and achieve optimal home-practice levels of self-acupressure techniques.

Project description:BackgroundThe management of prediabetes in the community setting is a global priority. We evaluated the feasibility of a 6-month multilevel practice nurse-led prediabetes dietary intervention which involved goal setting. The aim of this paper is to explore the weight loss goals and strategies reported by participants to achieve their weight loss goals as recorded by practice nurses, and report on factors that influenced dietary behaviours.MethodsThis study used a convergent mixed-methods design. A six-month pragmatic non-randomised pilot study with a qualitative process evaluation was conducted in two neighbouring provincial cities in New Zealand. A structured dietary intervention delivered by practice nurses was implemented in four practices in 2014-2016. Content analysis of the text and descriptive statistics were used to analyse the data.ResultsOne hundred and fifty seven people with prediabetes were enrolled (85 intervention, 72 control). The intervention group lost a mean 1.3 kg more than the control group (p < .0.001). The majority of the intervention group indicated either a high level of readiness (n = 42, 53%) or some readiness (n = 31, 39%) to make food changes. The majority of weight loss goals aligned with clinical guidelines (between 5 and 10% of body weight). While just over half (n = 47, 55%) demonstrated weight loss at the end of the six month period, the majority of participants did not achieve their predetermined weight loss goal (n = 78, 83%). Gender, ethnicity and budget were not related to weight loss at six months. Readiness to change and reported challenges to making dietary changes were related to weight loss at six months. Negative factors or set-backs included sporadic adherence to diet due to other health problems, change in context or environment and coping with ill health, most notably stress and low mood.ConclusionsThe data relating to weight loss and dietary goals provided insight into the challenges that people faced in making dietary changes for weight loss across a six month period. Simplifying goal setting to those goals with the greatest potential clinical impact or the greatest significance to the person, in a socially supportive environment, may increase the success of goal achievement.Trial registrationANZCTR ACTRN1261500080656.
