Background
The effectiveness of reinforcing exercise behavior with material incentives is unclear.
Purpose
Conduct a systematic review of existing research on material incentives for exercise, organized by incentive strategy.
Methods
Ten studies conducted between January 1965 and June 2013 assessed the impact of incentivizing exercise compared to a non-incentivized control.
Results
There was significant heterogeneity between studies regarding reinforcement procedures and outcomes. Incentives tended to improve behavior during the intervention while findings were mixed regarding sustained behavior after incentives were removed.
Conclusions
The most effective incentive procedure is unclear given the limitations of existing research. The effectiveness of various incentive procedures in promoting initial behavior change and habit formation, as well as the use of sustainable incentive procedures should be explored in future research.
BackgroundHealthcare financing through health insurance is gaining traction as developing countries strive to achieve universal health coverage and address the limited access to critical health services for specific populations including pregnant women and their children. However, these reforms are taking place despite limited evaluation of impact of health insurance on maternal health in developing countries including Kenya. In this study we evaluate the association of health insurance with access and utilization of obstetric delivery health services for pregnant women in Kenya.MethodsNationally representative data from the Kenya Demographic and Health Survey 2008–09 was used in this study. 4082 pregnant women with outcomes of interest - Institutional delivery (Yes/No – delivery at hospital, dispensary, maternity home, and clinic) and access to skilled birth attendants (help by a nurse, doctor, or trained midwife at delivery) were selected from 8444 women ages 15–49 years. Linear and logistic regression, and propensity score adjustment are used to estimate the causal association of enrollment in insurance on obstetric health outcomes.ResultsMothers with insurance are 23 percentage points (p < 0.01) more likely to deliver at an institution and 20 percentages points (p < 0.01) more likely have access to skilled birth attendants compared to those not insured. In addition mothers of lower socio-economic status benefit more from enrollment in insurance compared to mothers of higher socio-economic status. For both institutional delivery and access to skilled birth attendants, the average difference of the association of insurance enrollment compared to not enrolling for those of low SES is 23 percentage points (p < 0.01), and 6 percentage points (p < 0.01) for those of higher SES.ConclusionsEnrolling in health insurance is associated with increased access and utilization of obstetric delivery health services for pregnant women. Notably, those of lower socio-economic status seem to benefit the most from enrollment in insurance.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-017-2397-7) contains supplementary material, which is available to authorized users.

Populations with intensive health care needs and high care costs may be attracted to insurance plans that have high quality ratings, but patients may be likely to disenroll from a plan if their care needs are not met. We assessed the association between publicly reported Medicare Advantage plan star ratings and voluntary disenrollment of incident dialysis patients in the following year over the period 2007-13. We found that Medicare Advantage (MA) plans with lower star ratings had significantly higher rates of disenrollment by incident dialysis patients in the following year. Compared to MA plans with 4.0 or more stars, adjusted disenrollment rates were 3.9 percentage points higher for plans with 3.5 stars, 5.0 percentage points higher for those with 3.0 stars, and 12.1 percentage points higher for those with 2.5 or fewer stars. These findings suggest that low plan quality may lead to increased expenditures, as this high-cost population generally must shift from Medicare Advantage to traditional Medicare upon disenrollment.
Objectives
The main purpose of this paper was to assess the differences between Seguro Popular (SP) and employer-based health insurance in the use of preventive services, including screening tests for diabetes, cholesterol, hypertension, cervical cancer and prostate cancer among older adults at more than a decade of health care reform in Mexico.
Methods
Logistic regression models were used with data from the Mexican Health and Nutrition Survey 2012.
Results
After adjusting for other factors influencing preventive service utilization, SP enrollees were more likely to use screening tests for diabetes, cholesterol, hypertension and cervical cancer than the uninsured; however, those in employment-based and private insurances had higher odds of using preventive care for most of these services, except Pap smears.
Discussion
Despite all the evidence that suggests that Seguro Popular has increased access to health insurance for the poor, inequalities in healthcare access still exist in Mexico.
In Latin America, men who have sex with men (MSM) remain disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool and has been FDA approved in the United States since 2012, but no Latin American state, with the recent exception of Brazil, has implemented PrEP guidelines. We carried out a multinational online survey of MSM in Latin America (n = 22698) in 2012 to assess whether MSM at highest risk of HIV acquisition (i.e., those engaging in condomless anal sex [CAS; n = 2606] and transactional sex [n = 1488]) had higher levels of awareness of PrEP, PrEP use and interest in participating in a PrEP trial. After adjusting for demographic and psychosocial characteristics including depressive symptoms, hazardous alcohol use, childhood sexual abuse, and sexual compulsivity, transactional sex and CAS were associated with increased PrEP awareness (aOR = 1.29, 95% CI: 1.05–1.59, p < .001 and aOR = 1.22, 95% CI: 1.11–1.34, p < .001, respectively) and PrEP trial interest (aOR = 1.45, 95% CI: 1.25–1.71, p < .001 and aOR = 1.74, 95% CI: 1.57–1.95, p < .001, respectively). Findings demonstrate substantial awareness of and interest in PrEP among MSM with behavioral risk factors for HIV in Latin America, suggesting that this region is primed for PrEP implementation, which has been slow.
Over the past two decades, nursing homes and home health care agencies have been influenced by several Medicare and Medicaid policy changes including the adoption of prospective payment for Medicare-paid postacute care and Medicaid-paid long-term home and community-based care reforms. This article examines how spending growth in these sectors was affected by state certificate-of-need (CON) laws, which were designed to limit the growth of providers and have remained unchanged for several decades. Compared with states without CON laws, Medicare and Medicaid spending in states with CON laws grew faster for nursing home care and more slowly for home health care. In particular, we observed the slowest growth in community-based care in states with CON for both the nursing home and home health industries. Thus, controlling for other factors, public postacute and long-term care expenditures in CON states have become dominated by nursing homes.
