The Role of Social Media in Online Weight Management: Systematic Review

Background Social media applications are promising adjuncts to online weight management interventions through facilitating education, engagement, and peer support. However, the precise impact of social media on weight management is unclear. Objective The objective of this study was to systematically describe the use and impact of social media in online weight management interventions. Methods PubMed, PsycINFO, EMBASE, Web of Science, and Scopus were searched for English-language studies published through March 25, 2013. Additional studies were identified by searching bibliographies of electronically retrieved articles. Randomized controlled trials of online weight management interventions that included a social media component for individuals of all ages were selected. Studies were evaluated using 2 systematic scales to assess risk of bias and study quality. Results Of 517 citations identified, 20 studies met eligibility criteria. All study participants were adults. Because the included studies varied greatly in study design and reported outcomes, meta-analysis of interventions was not attempted. Although message boards and chat rooms were the most common social media component included, their effect on weight outcomes was not reported in most studies. Only one study measured the isolated effect of social media. It found greater engagement of participants, but no difference in weight-related outcomes. In all, 65% of studies were of high quality; 15% of studies were at low risk of bias. Conclusions Despite the widespread use of social media, few studies have quantified the effect of social media in online weight management interventions; thus, its impact is still unknown. Although social media may play a role in retaining and engaging participants, studies that are designed to measure its effect are needed to understand whether and how social media may meaningfully improve weight management.

Social media use in chronic disease: A systematic review and novel taxonomy

PURPOSE The purpose of this study is to evaluate clinical outcomes from applications of contemporary social media in chronic disease; to develop a conceptual taxonomy to categorize, summarize, and then analyze the current evidence base; and to suggest a framework for future studies on this topic. METHODS We performed a systematic review of MEDLINE via PubMed (January 2000 to January 2015) of studies reporting clinical outcomes on leading contemporary social media (ie, Facebook, Twitter, Wikipedia, YouTube) use in 10 chronic diseases. Two reviewers independently performed data extraction and quality assessment; characterization of study outcomes as positive, negative, neutral, or undefined impact; and inductive, thematic analysis to develop our taxonomy. RESULTS Of 378 citations identified, 42 studies examining the use of Facebook (n = 16), blogs (n = 13), Twitter (n = 8), wikis (n = 5), and YouTube (n = 4) on outcomes in cancer (n = 14), depression (n = 13), obesity (n = 9), diabetes (n = 4), heart disease (n = 3), stroke (n = 2), and chronic lower respiratory tract infection (n = 1) were included. Studies were classified as support (n = 16), patient education (n = 10), disease modification (n = 6), disease management (n = 5), and diagnosis (n = 5) within our taxonomy. The overall impact of social media on chronic disease was variable, with 48% of studies indicating benefit, 45% neutral or undefined, and 7% suggesting harm. Among studies that showed benefit, 85% used either Facebook or blogs, and 40% were based within the domain of support. CONCLUSIONS Using social media to provide social, emotional, or experiential support in chronic disease, especially with Facebook and blogs, appears most likely to improve patient care.

Characterization of Medicaid policy for immediate postpartum contraception

OBJECTIVE Long-acting reversible contraception (LARC) is safe, effective and cost-saving when provided immediately postpartum but currently underutilized due to nonreimbursement by Medicaid and other insurers. The objectives of this study were to (a) determine which state Medicaid agencies provide specific reimbursement for immediate postpartum LARC and (b) identify modifiable policy-level barriers and facilitators of immediate postpartum LARC access. STUDY DESIGN We conducted semistructured telephone interviews with representatives of 40 Medicaid agencies to characterize payment methodology for immediate postpartum LARC. We coded transcripts using grounded theory and content analysis principles. RESULTS Three categories of immediate postpartum LARC payment methodology emerged: state Medicaid agency (a) provides separate or increased bundled payment (n=15), (b) is considering providing enhanced payment (n=9) or (c) is not considering enhanced payment (n=16). Two major themes emerged related to Medicaid decision-making about immediate postpartum LARC coverage: (a) Health effects: States with payment for immediate postpartum LARC frequently cited improved maternal/child health outcomes as motivating their reimbursements. Conversely, states without payment expressed misinformation about LARCs clinical effects and lack of advocacy from local providers about clinical need for this service. (b) Financial implications: States providing payment emphasized overall cost savings. Conversely, states without reimbursement expressed concern about immediate budget constraints and potential adverse impact on existing global payment methodology for inpatient care. CONCLUSIONS Many states have recently provided Medicaid coverage of immediate postpartum LARC, and several other states are considering such coverage. Addressing misinformation about clinical effects and concerns about cost-effectiveness of immediate postpartum LARC may promote adoption of immediate postpartum LARC reimbursement in Medicaid agencies currently without it. IMPLICATIONS Medicaid policy for reimbursement of immediate postpartum LARC is evolving rapidly across the US. Our findings suggest several concrete strategies to remove policy-level barriers and promote facilitators of immediate postpartum LARC.

Detection of Epstein-Barr Virus in Rapidly Growing Fibroadenomas of the Breast in Immunosuppressed Hosts

Fibroadenomas are the most common benign tumors of the female breast and are associated with a slight increase in the risk of subsequent breast cancer. Multiple fibroadenomas have been described in patients after renal transplantation and are thought to be secondary to drug-related growth stimulation. Epstein-Barr virus (EBV) has been detected in many neoplasms, including breast cancer. We set out to investigate whether EBV plays a role in the development of rapidly growing fibroadenomas in immunocompromised patients. We studied 19 fibroadenomas and one invasive ductal carcinoma that developed after organ transplantation or treatment for lupus erythematosus. As a control group we included 11 fibroadenomas from non-immunocompromised patients. DNA was amplified using polymerase chain reaction (PCR) of the EBV-encoded small RNA (EBER-2) DNA sequence. EBV latent membrane protein 1 (LMP-1) transcripts were amplified using reverse transcription (RT) PCR. Immunohistochemical (IHC) staining for LMP-1 protein was performed. A total of 9 out of 20 tumors (45%) were concordantly positive by PCR and IHC. IHC stained exclusively the epithelial cells. All the fibroadenomas in non-immunocompromised patients were negative for LMP-1 (Fisher’s exact test P = .0006). These data suggest that EBV is associated with fibroadenomas in this immunosuppressed population and that the infection is specifically localized to epithelial cells. This is the first study suggesting a role for EBV in the pathogenesis of fibroadenomas.

Perspectives about and approaches to weight gain in pregnancy: a qualitative study of physicians and nurse midwives

BackgroundOver one third of reproductive age women in the US are obese. Pregnancy is a strong risk factor for obesity, with excess weight gain as the greatest predictor of long term obesity. The majority of pregnant women gain more weight than recommended by the Institute of Medicine guidelines. The objective of this study was to understand prenatal care providers’ perspectives on weight gain during pregnancy.MethodsSemi-structured qualitative interviews of 10 prenatal care providers (three family physicians, three obstetricians, and four nurse midwives) at a University Hospital in the Midwest, that included the ranking of important prenatal issues, and open-ended questions addressing: 1) general perceptions; 2) approach with patients; and 3) clinical care challenges.ResultsProviders felt that appropriate weight gain during pregnancy was not a high priority. Many providers waited until patients had gained excess weight before addressing the issue, were not familiar with established guidelines, and lacked resources for patients. Providers also believed that their counseling had low impact on patients, avoided counseling due to sensitivity of the topic, and believed that patients were more influenced by other factors, such as their family, habits, and culture.ConclusionsBoth providers and patients may benefit from increased awareness of the morbidity of excess weight gain during pregnancy. Practice-level policies that support the monitoring and management of weight gain during pregnancy could also improve care. Research that further investigates the barriers to appropriate weight gain is warranted.

Potential Adult Medicaid Beneficiaries Under the Patient Protection and Affordable Care Act Compared With Current Adult Medicaid Beneficiaries

PURPOSE Under health care reform, states will have the opportunity to expand Medicaid to millions of uninsured US adults. Information regarding this population is vital to physicians as they prepare for more patients with coverage. Our objective was to describe demographic and health characteristics of potentially eligible Medicaid beneficiaries. METHODS We performed a cross-sectional study using data from the National Health and Nutrition Examination Survey (2007–2010) to identify and compare adult US citizens potentially eligible for Medicaid under provisions of the Patient Protection and Affordable Care Act (ACA) with current adult Medicaid beneficiaries. We compared demographic characteristics (age, sex, race/ethnicity, education) and health measures (self-reported health status; measured body mass index, hemoglobin A1c level, systolic and diastolic blood pressure, depression screen [9-item Patient Health Questionnaire], tobacco smoking, and alcohol use). RESULTS Analyses were based on an estimated 13.8 million current adult non-elderly Medicaid beneficiaries and 13.6 million nonelderly adults potentially eligible for Medicaid. Potentially eligible individuals are expected to be more likely male (49.2% potentially eligible vs 33.3% current beneficiaries; P <.001), to be more likely white and less likely black (58.8% white, 20.0% black vs 49.9% white, 25.2% black; P = .02), and to be statistically indistinguishable in terms of educational attainment. Overall, potentially eligible adults are expected to have better health status (34.8% “excellent” or “very good,” 40.4% “good”) than current beneficiaries (33.5% “excellent” or “very good,” 31.6% “good”; P <.001). The proportions obese (34.5% vs 42.9%; P = .008) and with depression (15.5% vs 22.3%; P = .003) among potentially eligible individuals are significantly lower than those for current beneficiaries, while there are no significant differences in the expected prevalence of diabetes or hypertension. Current tobacco smoking (49.2% vs 38.0%; P = .002), and moderate and heavier alcohol use (21.6% vs 16.0% and 16.5% vs 9.8%; P <.001, respectively) are more common among the potentially eligible population than among current beneficiaries. CONCLUSIONS Under the ACA, physicians can anticipate a potentially eligible Medicaid population with equal if not better current health status and lower prevalence of obesity and depression than current Medicaid beneficiaries. Federal Medicaid expenditures for newly covered beneficiaries therefore may not be as high as anticipated in the short term. Given the higher prevalence of tobacco smoking and alcohol use, however, broad enrollment and engagement of this potentially eligible population is needed to address their higher prevalence of modifiable risk factors for future chronic disease.

Inadequate Hydration, BMI, and Obesity Among US Adults: NHANES 2009–2012

PURPOSE Improving hydration is a strategy commonly used by clinicians to prevent overeating with the goal of promoting a healthy weight among patients. The relationship between weight status and hydration, however, is unclear. Our objective was to assess the relationship between inadequate hydration and BMI and inadequate hydration and obesity among adults in the United States. METHODS Our study used a nationally representative sample from the National Health and Nutrition Examination Survey (NHANES) 2009 to 2012, and included adults aged 18 to 64 years. The primary outcome of interest was body mass index (BMI), measured in continuous values and also categorized as obese (BMI ≥30) or not (BMI <30). Individuals with urine osmolality values of 800 mOsm/kg or greater were considered to be inadequately hydrated. Linear and logistic regressions were performed with continuous BMI and obesity status as the outcomes, respectively. Models were adjusted for known confounders including age, race/ethnicity, sex, and income-to-poverty ratio. RESULTS In this nationally representative sample (n = 9,528; weighted n = 193.7 million), 50.8% were women, 64.5% were non-Hispanic white, and the mean age was 41 years. Mean urine osmolality was 631.4 mOsm/kg (SD = 236.2 mOsm/kg); 32.6% of the sample was inadequately hydrated. In adjusted models, adults who were inadequately hydrated had higher BMIs (1.32 kg/m2; 95% CI, 0.85–1.79; P <.001) and higher odds of being obese (OR = 1.59; 95% CI, 1.35–1.88; P <.001) compared with hydrated adults. CONCLUSION We found a significant association between inadequate hydration and elevated BMI and inadequate hydration and obesity, even after controlling for confounders. This relationship has not previously been shown on a population level and suggests that water, an essential nutrient, may deserve greater focus in weight management research and clinical strategies.

Inpatient Postpartum Long-Acting Reversible Contraception and Sterilization in the United States, 2008-2013

OBJECTIVE To measure rates of long-acting reversible contraception (LARC), including intrauterine devices and contraceptive implants, and tubal sterilization during delivery hospitalizations and correlates of their use. METHODS This retrospective cohort study used the 2008-2013 National Inpatient Sample, a publicly available all-payer database. We identified delivery hospitalizations with the International Classification of Diseases, 9th Revision, Clinical Modification codes for intrauterine device insertion, contraceptive implant insertion, and tubal sterilization. We used weighted multivariable logistic regression to examine associations between predictors (age, delivery mode, medical comorbidity, payer, hospital type, geographic region, and year) and likelihood of LARC and sterilization and to compare characteristics of LARC and sterilization users. RESULTS Our sample included 4,691,683 discharges, representing 22,667,204 delivery hospitalizations. Long-acting reversible contraception insertion increased from 1.86 per 10,000 deliveries (2008-2009) to 13.5 per 10,000 deliveries (2012-2013; P<.001); tubal sterilization remained stable (711-683 per 10,000 deliveries; P=.24). In multivariable analysis adjusting for all predictors, compared with neither LARC nor sterilization, LARC use was highest among women with medical comorbidities (count per 10,000 deliveries: 15.04, standard error 2.11, adjusted odds ratio [OR] 1.92, 95% confidence interval [CI] 1.72-2.13), nonprivate payer (13.50, standard error 2.14, adjusted OR 5.23, 95% CI 3.82-7.16), and at urban teaching hospitals (14.92, standard error 2.25, adjusted OR 20.85, 95% CI 12.73-34.15). Sterilization was least likely among women aged 24 years or younger (251.04, standard error 4.88, adjusted OR 0.12 95% CI 0.12-0.13, compared with 35 years or older) and most likely with cesarean delivery (1,568.74, standard error 20.81, adjusted OR 6.25, 95% CI 5.88-6.63). Comparing only LARC and sterilization users, LARC users tended to have nonprivate insurance (84.95% compared with 57.17%, adjusted OR 1.90, 95% CI 1.38-2.63) and deliver at urban teaching hospitals (94.65% compared with 45.47%, adjusted OR 38.39, 23.52-62.64) in later study years (2012-2013; 55.72% compared with 32.18%, adjusted OR 8.26, 95% CI 4.42-15.44, compared with 2008-2009). CONCLUSION Long-acting reversible contraception insertion increased from 1.86 to 13.5 per 10,000 deliveries but remained less than 2% of the sterilization rate. Inpatient postpartum LARC insertion is more likely among sicker, poorer women delivering at urban teaching hospitals.

Implications of teen birth for overweight and obesity in adulthood

OBJECTIVE The objective of this study was to examine whether teen birth was independently associated with overweight and obesity in a US cohort. STUDY DESIGN We examined whether teen birth is independently associated with overweight and obesity in a multiyear US cohort using the 2001-2010 National Health and Nutrition Examination Survey, a nationally representative cross-sectional survey of the US civilian, noninstitutionalized population. We performed multinomial logistic regression adjusting for survey cohort, age at survey, race, education, and parity. We included women 20-59 years old at the time of survey, with at least 1 live birth, not currently or recently pregnant (unweighted, n = 5220; weighted, n = 48.4 million). Our outcome measure was the effect of teen birth on subsequent overweight and obesity. RESULTS In bivariate analyses, women with a teen birth were significantly more likely than women without a teen birth to be overweight (relative risk ratios [RRRs], 1.61; 95% confidence interval [CI], 1.37-1.90) or obese (RRR, 1.84; 95% CI, 1.56-2.16) at the time of the survey. In multivariate models, women with a teen birth remained significantly more likely to be overweight (adjusted RRR, 1.33; 95% CI, 1.10-1.62) or obese (adjusted RRR, 1.32; 95% CI, 1.09-1.61) than women without a teen birth. CONCLUSION For women in the United States, giving birth as a teen is associated with subsequent overweight/obese status later in life. To inform clinical and policy interventions with the goal to improve the long-term health of teenage mothers, future studies must examine modifiable physiological and sociomedical reasons for early child-bearing and later risk of obesity.

Recruiting pregnant patients for survey research: A head to head comparison of social media-based versus clinic-based approaches

Background Recruiting a diverse sample of pregnant women for clinical research is a challenging but crucial task for improving obstetric services and maternal and child health outcomes. Objective To compare the feasibility and cost of recruiting pregnant women for survey research using social media-based and clinic-based approaches. Methods Advertisements were used to recruit pregnant women from the social media website Facebook. In-person methods were used to recruit pregnant women from the outpatient clinic of a large, tertiary care center. In both approaches, potential respondents were invited to participate in a 15-minute Web-based survey. Each recruitment method was monitored for 1 month. Using bivariate statistics, we compared the number, demographic characteristics, and health characteristics of women recruited and the cost per completed survey for each recruitment method. Results The social media-based approach recruited 1178 women and the clinic-based approach recruited 219 women. A higher proportion of subjects recruited through social media identified as African American (29.4%, 207/705 vs 11.2%, 20/179), reported household incomes <US
