Lifestyle strategies after intentional weight loss: results from the MAINTAIN-pc randomized trial.
The aim of this study was to explore the strategies related with successful long-term weight loss maintenance. Researchers analyzed data from the 24-month Maintaining Activity and Nutrition Through Technology-Assisted Innovation in Primary Care (MAINTAIN-pc) trial. MAINTAIN-pc recruited 194 adults with recent intentional weight loss and randomized participants a group using tracking tools plus coaching (i.e., coaching group) or tracking tools without coaching (i.e., tracking-only group). The participants reported the lifestyle strategies they utilized in the previous 6 months, including self-monitoring, group support, behavioral skills, and professional support. The study found that at baseline, 100% used behavioral skills, 73% used group support, 69% used self-monitoring, and 68% used professional support in the past 6 months; at 24 months, the rates were 98%, 60%, 75%, and 61%, respectively. The number of participants using individual strategies did not vary significantly over time, but the overall number of strategies participants reported decreased. A greater number of strategies were utilized at baseline and 6 months compared to 12- and 24-month follow-ups. The coaching group utilized a greater number of strategies at months 6 and 12 than the tracking-only group. Consistent utilization of professional support strategies over the 24-month study period was related with less weight regain.

Impact of electronic health record-coaching features in weight change: a secondary analysis from the MAINTAIN-pc randomized trial.
This study evaluated whether coaching features were successfully transmitted via electronic health record (EHR) communication and to evaluate their relationship with weight change in a previously tested EHR-based coaching intervention. The authors conducted a secondary analysis from the Maintaining Activity and Nutrition through Technology-Assisted Innovation in Primary Care (MAINTAIN-pc) study randomized clinical trial in nine primary care practices and one specialty practice (endocrinology) affiliated with the University of Pittsburgh Medical Center. Eligible participants were aged 18 to 75 years, had intentional 5% weight loss in the previous 2 years, had access to an internet-connected computer, and had receipt of care from a University of Pittsburgh Medical Center primary care provider. Participants content with intervention delivery via the EHR and those who felt a strong connection to their coach had significantly less weight regain. Participants who had needs unmet by the intervention (e.g., "in-person" support in a group setting or individual settings) regained more weight. The results suggest heterogeneity in the patient population regarding preference for in-person versus EHR-based coaching formats.

Characteristics of achieving clinically important weight loss in two paediatric weight management interventions.
The purpose of this study was to examine characteristics and lifestyle behaviors associated with achieving clinically important weight loss (CIWL) in two pediatric weight management interventions (PWMIs). Findings showed that, in this analysis of children enrolled in PWMIs, achieving CIWL was associated with younger age, not having severe obesity, and consuming fewer sugary beverages at the end of the intervention.

Executive function in individuals with clinically significant weight loss via behavioral intervention.
Researchers sought to characterize executive function (EF) in individuals who achieved clinically significant weight loss via behavioral intervention and to examine potential differences in EF between those who maintained versus regained lost weight. The study sample consisted primarily of women over age 50 with obesity; approximately half self-identified as African-American. The researchers found that most individuals with obesity who achieved clinically significant weight loss via behavioral intervention had average to above average EF; individuals who maintained their lost weight performed better on tests of decision-making.

Using simulation modeling to guide the design of the Girl Scouts Fierce & Fit Program.
The goal of this study was to see if computational modeling would help to revise the design of the Girl Scouts Fierce & Fit Program. The Girl Scouts of Central Maryland worked with the researchers to develop a computational simulation model representing the 250 adolescent girls who were participating in the program to determine how their diets and physical activity affected their BMI and subsequent outcomes, including costs. As a result, the program changed from 6 weeks meeting twice a week with 5 minutes of physical activity each session to meeting 12 weeks with 30 minutes of physical activity each session. Cost savings were estimated at an additional $84,828 in lifetime direct medical costs, $81,365 in lifetime productivity losses, and 7.85 quality-adjusted life-years.

Effect of electronic health record-based coaching on weight maintenance: a randomized trial.
This study compared long-term weight regain after participation in a weight loss management program using an electronic health record (EHR)-based weight maintenance intervention program. Participants were adult outpatients with a BMI of 25 kg/m2 or higher, had intentional weight loss of at least 5% in the previous 2 years, and had no bariatric procedures in the previous 5 years. The EHR tools included weight, diet and physical activity tracking sheets, standardized surveys and reminders. Patients were randomly assigned to the coaching or non-coaching group. They were tracked for 24 months with 24 scheduled contacts. Results showed patients who used the EHR tools plus coaching had less weight regain than patients using EHR tools alone.

Lifestyle habits associated with weight regain after intentional loss in primary care patients participating in a randomized trial.
This study examined lifestyle habits associated with weight regain at 6 and 24 months after intentional loss in primary care patients. This randomized trial used adult primary care patients who had a recent weight loss of at least 5%. Lifestyle habits measured using the Connor Diet Habit Survey included consumption of low-fat foods, fish, desserts, sugary beverages, fruits and vegetables and eating at restaurants; moderate-vigorous physical activity by self-report; steps recorded on a pedometer; and sedentary behavior by self-report. Participants had a mean age of 53.4 years, were 26% male and 88% white. Overall, they maintained weight loss at 6 months, but began to regain weight at 24 months. The habits most attributed to weight regain included more eating at restaurants, less fish consumption, and less physical activity. More sedentary behavior was associated with weight regain at 6 months, and reduced consumption of low-fat foods and more desserts and sugary beverages were associated with weight regain at 24 months.

Eat, pray, move: a pilot cluster randomized controlled trial of a multilevel church-based intervention to address obesity among African Americans and Latinos.
The purpose of this study was to implement a multilevel, church-based intervention with diverse disparity populations using community-based participatory research and evaluate feasibility, acceptability, and preliminary effectiveness in improving obesity-related outcomes. The investigators concluded that the intervention resulted in small improvements in obesity outcomes. They assert that a longer time line is needed to fully implement and assess effects of community and congregation environmental strategies and to allow for potential larger impacts of the intervention.

Parent-perceived stress and its association with children's weight and obesity-related behaviors.
Psychosocial stress is associated with obesity in adult and pediatric populations, but few studies have examined the relationship between parent-perceived stress and risk of child obesity and related behaviors. In this study, the investigators studied 689 pairs of parents and children aged 2 to 12 in Massachusetts with a body mass index (BMI) at or above the 85th percentile. The investigators found that among children with overweight or obesity, parent-perceived stress was associated with fast-food consumption and physical activity.

The practice gap: national estimates of screening and counseling for alcohol, tobacco, and obesity.
The authors of this study estimated screening and counseling rates for tobacco and alcohol use, and obesity by using a nationally representative sample of adults aged 35 years and older. Receipt of the recommended level of services ranged from nearly two-thirds for obesity and tobacco use to less than half for alcohol misuse. The authors conclude that care delivery shows significant room for improvement, but primary care practices may need additional resources to raise their screening and counseling rates.

Physical activity in adolescents and children and relationship to metabolic health.
The purpose of this review was to summarize recent developments relating to the role of physical activity in insulin resistance and increased metabolic health in children and adolescents. Recent findings confirm the role of physical activity in decreasing insulin resistance and metabolic syndrome, but the authors note that the current literature is limited by unstandardized research methods and definitions. Future research that addresses these issues in order to offer targeted physical activity interventions is recommended.

Let's talk numbers: a qualitative study of community-dwelling US adults to understand the role of numeracy in the management of heart failure.
This qualitative study examined the role of numeracy (basic number skills) in the management of patients with heart failure (HF). Thirty men and women aged 47-89 years with a history of HF were recruited from an urban academic primary care practice. Participants all had a history of HF within the past year, were seen at the practice within the last year, and had been hospitalized for HF within the last 6 months. They were interviewed about their numeracy to help manage monitoring weight, maintaining a low-salt diet, and monitoring blood pressure. A wide range of knowledge and understanding was found and fear served as a barrier and facilitator to carrying out HF self-care tasks involving numbers. If the patient has a caregiver who also lacks those skills or does not have HF care training, patients may not be managing their HF as well as they should.

Bidirectional relationships between weight change and sleep apnea in a behavioral weight loss intervention.
This study examined the relationship between weight change and obstructive sleep apnea (OSA) in the context of behavioral weight loss intervention. A total of 114 adults who were overweight or obese participated in a 12-month behavioral weight loss intervention program from April 2012 to February 2015. Over half (58%) had OSA at the baseline. Those with OSA were found to lose less weight and were less adherent to daily calorie and activity goals. The results suggest that OSA screening should be used before attempting weight loss and also may indicate additional behavioral counseling.

Simulating the impact of crime on African American women's physical activity and obesity.
The objective of this study was to quantify the impact of crime on physical activity location accessibility, leisure-time physical activity (LTPA), and obesity among African American women. The study’s simulations showed that crime may serve as a barrier to LTPA. Reducing crime and increasing propensity to exercise through multilevel interventions may promote greater than linear declines in obesity prevalence.

Behavioral lifestyle interventions for moderate and severe obesity: a systematic review.
This study reviews evidence of behavioral lifestyle interventions for weight loss in this population. Evidence for the effectiveness of behavioral interventions versus pharmacological or surgical treatment was limited. Comprehensive and intensive behavioral interventions can result in clinically significant, albeit modest, weight loss in this obese subpopulation but may not result in significant improvements in other cardiometabolic risk factors.

Moderate and vigorous intensity exercise during pregnancy and gestational weight gain in women with gestational diabetes.
The researchers estimated the associations of exercise intensity during pregnancy with the rate of gestational weight gain (GWG) from gestational diabetes (GDM) diagnosis to delivery. Upon stratification by prepregnancy overweight/obesity, they found that significant associations were only observed for BMI greater than or equal to 25.0. There were no associations observed for moderate intensity exercise.

Change in physical activity and sedentary time associated with 2-year weight loss in obese adults with osteoarthritis.
The investigators examined if changes in moderate-to-vigorous physical activity (MVPA), light activity, and sedentary behavior are related to weight change over a 2-year period in obese adults with elevated risk for knee osteoarthritis. They found that small increases in MVPA and decreases in sedentary time over 2 years were associated with weight loss among adults with obesity and with or at elevated risk for knee osteoarthritis.
