Racial/ethnic representation in lifestyle weight loss intervention studies in the United States: A systematic review.

Obesity remains a persistent public health and health disparity concern in the United States. Eliminating health disparities, particularly among racial/ethnic minority groups, is a major health priority in the US. The primary aim of this review was to evaluate representation of racial/ethnic sub-group members in behavioral weight loss interventions conducted among adults in the United States. The secondary aims were to assess recruitment and study design approaches to include racial/ethnic groups and the extent of racial/ethnic sub-group analyses conducted in these studies. PubMed, PsycInfo, Medline, and CINAHL were searched for behavioral weight loss intervention trials conducted in 2009-2015 using keywords: weight, loss, overweight, obese, intervention and trial. Most of the 94 studies included a majority of White participants compared to any other racial/ethnic group. Across the included studies, 58.9% of participants were White, 18.2% were African American, 8.7% were Hispanic/Latino, 5.0% were Asian and 1.0% were Native Americans. An additional 8.2% were categorized as "Other". Nine of the 94 studies exclusively included minority samples. Lack of adequate representation of racial and ethnic minority populations in behavioral trials limits the generalizability and potential public health impact of these interventions to groups that might most benefit from weight loss. Given racial/ethnic disparities in obesity rates and the burden of obesity and obesity-related diseases among minority groups in the United States, greater inclusion in weight loss intervention studies is warranted.

Society for Health Psychology (APA Division 38) and Society of Behavioral Medicine joint position statement on the Medicare Diabetes Prevention Program.

Beginning in January 2018, the Centers for Medicare and Medicaid Services (CMS) plans to cover the Diabetes Prevention Program (DPP), also referred to as Medicare DPP. The American Psychological Association Society for Health Psychology (SfHP) and the Society for Behavioral Medicine (SBM) reviewed the proposed plan. SfHP and SBM are in support of the CMS decision to cover DPP for Medicare beneficiaries but have a significant concern that aspects of the proposal will limit the public health impact. Concerns include the emphasis on weight outcomes to determine continued coverage and the lack of details regarding requirements for coaches. SfHP and SBM are in strong support of modifications to the proposal that would remove the minimum weight loss stipulation to determine coverage and to specify type and qualifications of "coaches."

Access to care and use of the Internet to search for health information: results from the US National Health Interview Survey.

BACKGROUND: The insurance mandate of the Affordable Care Act has increased the number of people with health coverage in the United States. There is speculation that this increase in the number of insured could make accessing health care services more difficult. Those who are unable to access care in a timely manner may use the Internet to search for information needed to answer their health questions. OBJECTIVE: The aim was to determine whether difficulty accessing health care services for reasons unrelated to insurance coverage is associated with increased use of the Internet to obtain health information. METHODS: Survey data from 32,139 adults in the 2011 National Health Interview Study (NHIS) were used in this study. The exposure for this analysis was reporting difficulty accessing health care services or delaying getting care for a reason unrelated to insurance status. To define this exposure, we examined 8 questions that asked whether different access problems occurred during the previous 12 months. The outcome for this analysis, health information technology (HIT) use, was captured by examining 2 questions that asked survey respondents if they used an online health chat room or searched the Internet to obtain health information in the previous 12 months. Several multinomial logistic regressions estimating the odds of using HIT for each reported access difficulty were conducted to accomplish the study objective. RESULTS: Of a survey population of 32,139 adults, more than 15.90% (n=5109) reported experiencing at least one access to care barrier, whereas 3.63% (1168/32,139) reported using online health chat rooms and 43.55% (13,997/32,139) reported searching the Internet for health information. Adults who reported difficulty accessing health care services for reasons unrelated to their health insurance coverage had greater odds of using the Internet to obtain health information. Those who reported delaying getting care because they could not get an appointment soon enough (OR 2.2, 95% CI 1.9-2.5), were told the doctor would not accept them as a new patient or accept their insurance (OR 2.1, 95% CI 1.7-2.5 and OR 2.1, 95% CI 1.7-2.5, respectively), or because the doctor's office was not open when they could go (OR 2.2, 95% CI 1.9-2.7) had more than twice the odds of using the Internet to obtain health information compared to those who did not report such access difficulties. CONCLUSIONS: People experiencing trouble accessing health care services for reasons unrelated to their insurance status are more likely to report using the Internet to obtain health information. Improving the accuracy and reliability of health information resources that are publicly available online could help those who are searching for information due to trouble accessing health care services.

Availability of tanning beds on US college campuses.

IMPORTANCE: Indoor tanning is widespread among young adults in the United States despite evidence establishing it as a risk factor for skin cancer. The availability of tanning salons on or near college campuses has not been formally evaluated. OBJECTIVE: To evaluate the availability of indoor tanning facilities on US college and university campuses (colleges) and in off-campus housing surrounding but not owned by the college. DESIGN, SETTING, AND PARTICIPANTS: This observational study sampled the top 125 US colleges and universities listed in US News and World Report. Investigators searched websites of the colleges and nearby housing and contacted them by telephone inquiring about tanning services. MAIN OUTCOMES AND MEASURES: Frequency of indoor tanning facilities on college campus and in off-campus housing facilities, as well as payment options for tanning. RESULTS: Of the 125 colleges, 48.0% had indoor tanning facilities either on campus or in off-campus housing, and 14.4% of colleges allow campus cash cards to be used to pay for tanning. Indoor tanning was available on campus in 12.0% of colleges and in off-campus housing in 42.4% of colleges. Most off-campus housing facilities with indoor tanning (96%) provide it free to tenants. Midwestern colleges had the highest prevalence of indoor tanning on campus (26.9%), whereas Southern colleges had the highest prevalence of indoor tanning in off-campus housing facilities (67.7%). Presence of on-campus tanning facilities was significantly associated with enrollment (P = .01), region (P = .02), and presence of a school of public health (P = .01) but not private vs public status (P = .18) or presence of a tobacco policy (P = .16). Presence of tanning facilities in off-campus housing was significantly associated with region (P = .002) and private vs public status (P = .01) but not enrollment (P = .38), tobacco policy (P = .80), or presence of a school of public health (P = .69). CONCLUSIONS AND RELEVANCE: Reducing the availability of indoor tanning on and around college campuses is an important public health target.

Access to healthy food stores modifies effect of a dietary intervention.

BACKGROUND: Recent evidence suggests that opening a grocery store in a food desert does not translate to better diet quality among community residents. PURPOSE: This study evaluated the influence of proximity to a healthy food store on the effect of a dietary behavioral intervention on diet among obese adults randomized to either a high fiber or American Heart Association diet intervention. METHODS: Participants were recruited from Worcester County, Massachusetts, between June 2009 and January 2012. Dietary data were collected via 24-hour recalls at baseline and 3, 6, and 12 months post-intervention. Based on in-store inspection data, a store was considered as having adequate availability of healthy foods if it had at least one item available in each of 20 healthy food categories. Linear models evaluated maximum change in dietary outcomes in relation to road distance from residence to the nearest June healthy food store. The analysis was conducted in January to June 2014. RESULTS: On average, participants (N=204) were aged 52 years, BMI=34.9, and included 72% women and 89% non-Hispanic whites. Shorter distance to a healthy food store was associated with greater improvements in consumption of fiber (b=-1.07 g/day per mile, p<0.01) and fruits and vegetables (b=-0.19 servings/day per mile, p=0.03) with and without covariate adjustment. CONCLUSIONS: The effectiveness of dietary interventions is significantly influenced by the presence of a supportive community nutrition environment. Considering the nationwide efforts on promotion of healthy eating, the value of improving community access to healthy foods should not be underestimated. CLINICAL TRIAL REGISTRATION NUMBER: NCT00911885.

A systematic review of electronic portal usage among patients with diabetes.

The objectives of this review were (1) to examine characteristics associated with enrollment and utilization of portals among patients with diabetes and (2) to identify barriers and facilitators of electronic patient portal enrollment and utilization. PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were systematically searched for papers reporting original research using quantitative or qualitative methods on characteristics, barriers, and facilitators associated with portal enrollment and utilization among patients with diabetes in the United States. The search was limited to articles published between February 1, 2005 (the date of the national symposium on personal health records) and January 1, 2014. Sixteen articles were identified. Of these, nine were quantitative, three were qualitative, and four used mixed-methods. Several demographic characteristics, having better-controlled diabetes, and providers who engaged in and encouraged portal use were associated with increased portal enrollment and utilization. Barriers to portal enrollment included a lack of patient (1) capacity, (2) desire, and (3) awareness of portal/portal functions. Barriers to portal utilization included (1) patient capacity, (2) lack of provider and patient buy-in to portal benefits, and (3) negative patient experiences using portals. Facilitators of portal enrollment and utilization were providers and family members recommending and engaging in portal use. Improved usability, increased access, educating patients how to use and benefit from portals, and greater endorsement by providers and family members might increase portal enrollment and utilization. As more providers and hospitals offer portals, addressing barriers and leveraging facilitators may help patients with diabetes achieve potential benefits.

Food preparation supplies predict children's family meal and home-prepared dinner consumption in low-income households.

Frequent family meals and home food preparation are considered important for children's nutritional health and weight maintenance. This cross-sectional study tested whether these parent-driven behaviors are related to the availability of food preparation supplies in low-income urban households. Caregivers of children ages 6-13 provided information on family meal frequency, child consumption of home-prepared dinners, household food insecurity, and attitudes towards cooking. Researchers used a newly developed Food Preparation Checklist (FPC) to assess the availability of 41 food preparation supplies during a physical audit of the home environment. Caregivers and children provided anthropometric measurements and jointly reported on child dietary intake. In ordinal logistic regression models, greater home availability of food preparation supplies was associated with more frequent family meals and child consumption of home-prepared dinners. Associations were independent of household financial strain, food insecurity, caregiver attitudes toward cooking, and sociodemographic characteristics. Fewer food preparation supplies were available in households characterized by greater food insecurity, lower income, and negative caregiver attitudes towards cooking, but did not differ by child or caregiver weight status. As in prior studies, more frequent family meals and consumption of home-prepared dinners were associated with healthier child dietary intake in several areas. We conclude that food preparation supplies are often limited in the most socioeconomically disadvantaged households, and their availability is related to the frequency with which children consume family meals and home-prepared dinners. The potential role of food preparation supplies as contributors to socioeconomic disparities in child nutritional health and obesity deserves further study.

The adoption and spread of a core-strengthening exercise through an online social network.

BACKGROUND: The present feasibility study describes engagement and spread of a Twitter-based core-strengthening challenge. METHODS: A challenge that entailed completing a core-strengthening exercise using a hashtag (#PlankADay) was circulated via Twitter. This study surveyed users who joined during the first 2 months of the challenge to describe their characteristics, including social support for exercise and to what extent they invited others to join. The study continued to track total users for 10 months. RESULTS: Of 407 individuals who joined in the first 2 months, 105 completed surveys. Among these, 81% were female and 86% white and mean age was 35.8. 72% participated for at least 1 month and 47% participated for at least 2 months. Survey participants reported that the challenge increased their enjoyment of abdominal exercise. Of the 68% of participants who invited others to participate, 28% recruited none, 66% recruited 1-5 users, and 6% recruited 10 or more users. Participants reported that online friends provided as much positive social support for exercise as family and in-person friends. In 14 months, 4941 users produced 76,746 tweets and mean total tweets per user was 15.86 (SD = 75.34; range = 1-2888). CONCLUSION: Online social networks may be a promising mechanism to spread brief exercise behaviors.

Socioeconomic status, energy cost, and nutrient content of supermarket food purchases.

BACKGROUND: The relative affordability of energy-dense versus nutrient-rich foods may promote socioeconomic disparities in dietary quality and obesity. Although supermarkets are the largest food source in the American diet, the associations between SES and the cost and nutrient content of freely chosen food purchases have not been described. PURPOSE: To investigate relationships of SES with the energy cost ($/1000 kcal) and nutrient content of freely chosen supermarket purchases. METHODS: Supermarket shoppers (n=69) were recruited at a Phoenix AZ supermarket in 2009. The energy cost and nutrient content of participants' purchases were calculated from photographs of food packaging and nutrition labels using dietary analysis software. Data were analyzed in 2010-2011. RESULTS: Two SES indicators, education and household income as a percentage of the federal poverty guideline (FPG), were associated with the energy cost of purchased foods. Adjusting for covariates, the amount spent on 1000 kcal of food was $0.26 greater for every multiple of the FPG, and those with a baccalaureate or postbaccalaureate degree spent an additional $1.05 for every 1000 kcal of food compared to those with no college education. Lower energy cost was associated with higher total fat and less protein, dietary fiber, and vegetables per 1000 kcal purchased. CONCLUSIONS: Low-SES supermarket shoppers purchase calories in inexpensive forms that are higher in fat and less nutrient-rich.

Translation of the diabetes prevention program into a community mental health organization for individuals with severe mental illness: a case study.

Individuals with severe mental illness (SMI) have significant health disparities. Wellness services embedded in community mental health organizations could lessen these disparities. This case study illustrates the integration of the Diabetes Prevention Program (DPP) lifestyle intervention into a community mental health organization. The Diffusion of Innovations Theory was used as a model for integration, which included a collaboration between researchers and the organization and qualitative work, culminating in a small pilot of the DPP led by peer specialists to test the feasibility of the DPP in this setting. Fourteen individuals with SMI participated in the 19-week intervention. Three dropped out, but the remaining 11 demonstrated 92% attendance. Weight loss was minimal, but the participants reported benefit and showed continued interest in the intervention. The use of a peer-led DPP in a community mental health organization is feasible and warrants further investigation to demonstrate efficacy.

Number of 24-hour diet recalls needed to estimate energy intake.

PURPOSE: Twenty-four-hour diet recall interviews (24HRs) are used to assess diet and to validate other diet assessment instruments. Therefore it is important to know how many 24HRs are required to describe an individual's intake. METHOD: Seventy-nine middle-aged white women completed seven 24HRs over a 14-day period, during which energy expenditure (EE) was determined by the doubly labeled water method (DLW). Mean daily intakes were compared to DLW-derived EE using paired t tests. Linear mixed models were used to evaluate the effect of call sequence and day of the week on 24HR-derived energy intake while adjusting for education, relative body weight, social desirability, and an interaction between call sequence and social desirability. RESULTS: Mean EE from DLW was 2115 kcal/day. Adjusted 24HR-derived energy intake was lowest at call 1 (1501 kcal/day); significantly higher energy intake was observed at calls 2 and 3 (2246 and 2315 kcal/day, respectively). Energy intake on Friday was significantly lower than on Sunday. Averaging energy intake from the first two calls better approximated true energy expenditure than did the first call, and averaging the first three calls further improved the estimate (p=0.02 for both comparisons). Additional calls did not improve estimation. CONCLUSIONS: Energy intake is underreported on the first 24HR. Three 24HRs appear optimal for estimating energy intake.

Sun protection motivational stages and behavior: skin cancer risk profiles.

OBJECTIVE: To create skin cancer risk profiles that could be used to predict sun protection among Midwest beachgoers. METHOD: Cluster analysis was used with study participants (N=239), who provided information about sun protection motivation and behavior, perceived risk, burn potential, and tan importance. Participants were clustered according to their risk profiles; 4 distinct risk profiles emerged. RESULTS: Analyses revealed that risk profiles were significantly different on sun protection motivation and behavior and marginally different in terms of sun tanning behavior. CONCLUSION: Given the complexity of risk factors, an examination of clusters, rather than factors in isolation, may more accurately depict sun protection behavior.
