ABSTRACT
BACKGROUND: Disparities in suicide rates by veteran status are particularly striking for women. Veterans Crisis Line (VCL) is a preventive strategy. OBJECTIVES: Examine the relationships and gender differences between VCL risk rating, and subsequent suicidal self-directed violence (SSDV) in the 12-months following VCL index call. METHODS: Cohort study of VCL callers in 2018. OUTCOMES: Dichotomized composite SSDV (non-fatal suicide event and/or suicide) in the 12 months following VCL call. RESULTS: Veterans with high/moderate VCL risk had significantly higher odds of SSDV (OR = 4.02, 95% CI: 3.75, 4.30). There were no gender/VCL risk interaction (p = 0.3605). We also examined the association of gender, combination of VCL risk and suicide attempt (SA) history, on SSDV. Differential odds of SSDV for gender and combined VCL risk and SA history combinations were observed (p = 0.0005). Compared to those with lower VCL risk without SA history, those with high/moderate VCL risk with SA history showed higher odds of SSDV. Magnitude was higher for men, than for women veterans. CONCLUSIONS AND RELEVANCE: Veterans Crisis Line risk assessment performs relatively stable across the gender binary and highlights potential gender differences when factoring in SA history. Combining risk assessment and attempt history may lead to effective suicide prevention strategies.

INTRODUCTION: Multiple U.S. localities have introduced legislation requiring sugar-sweetened beverage (SSB) warnings. This study effects of different warning designs on beverage selections and perceptions. STUDY DESIGN: The study was an RCT. SETTING/PARTICIPANTS: An online virtual convenience store and survey were used with a nationally representative sample of primary caregivers of 6-11-year-olds (n=961). Data were collected in January 2020 and analyzed in May-July 2020. INTERVENTION: Participants were randomized to view SSBs with 1 of 4 front-of-package label designs: (1) no-warning control, (2) health-related text warning, (3) sugar pictorial warning (image of beverage sugar content in cubes/teaspoons/packets with health-related warning text), or (4) health pictorial warning (image of possible health consequences of overconsuming SSBs with health-related warning text). MAIN OUTCOME MEASURES: Outcomes included participants' beverage choice for their child and perceptions of beverages, their assigned labels, and warning policies. RESULTS: Proportionally fewer participants chose a SSB in the sugar pictorial warning condition (-13.4 percentage points; 95% CI= -21.6 to -0.1 percentage points; p=0.007) and in the health pictorial warning condition (-14.7 percentage points; 95% CI= -22.8 to -0.1 percentage points; p=0.004) compared to the control. Sugar pictorial warnings led to more accurate added-sugar content estimates than all conditions and greater label trust and support for sugar-sweetened beverage warning policies than health pictorial warnings. CONCLUSIONS: SSB warning policies may be most effective if they mandate images of beverages' added sugar content accompanied by warning text. TRIAL REGISTRATION: This study is registered at www. CLINICALTRIALS: gov NCT03648138.

OBJECTIVE: To study the impact of Medicaid funding structures before and after the implementation of the Affordable Care Act (ACA) on health care access for Latinos in New York (Medicaid expansion), Florida (Medicaid non-expansion), and Puerto Rico (Medicaid block grant). DATA SOURCES: Pooled state-level data for New York, Florida, and Puerto Rico from the 2011-2019 Behavioral Risk Factor Surveillance System and data from the 2011-2019 American Community Survey and Puerto Rico Community Survey. STUDY DESIGN: Cross-sectional study using probit with predicted margins to separately compare four health care access measures among Latinos in New York, Florida, and Puerto Rico (having health insurance coverage, having a personal doctor, delayed care due to cost, and having a routine checkup). We also used difference-in-differences to measure the probability percent change of having any health insurance and any public health insurance before (2011-2013) and after (2014-2019) the ACA implementation among citizen Latinos in low-income households. DATA COLLECTION: The sample consisted of Latinos aged 18-64 residing in New York, Florida, and Puerto Rico from 2011 to 2019. PRINCIPAL FINDINGS: Latinos in Florida had the lowest probability of having health care access across all four measures and all time periods compared with those in New York and Puerto Rico. While Latinos in Puerto Rico had greater overall health care access compared with Latinos in both states, health care access in Puerto Rico did not change over time. Among citizen Latinos in low-income households, New York had the greatest post-ACA probability of having any health insurance and any public health insurance, with a growing disparity with Puerto Rico (9.7% any [1.6 SE], 5.2% public [1.8 SE]). CONCLUSIONS: Limited Medicaid eligibility (non-expansion of Florida's Medicaid program) and capped Medicaid funds (Puerto Rico's Medicaid block grant) contributed to reduced health care access over time, particularly for citizen Latinos in low-income households.

BACKGROUND: Bereaved family members of racial/ethnic minority Veterans are less likely than families of White Veterans to provide favorable overall ratings of end-of-life (EOL) care quality; however, the underlying mechanisms for these differences have not been explored. The objective of this study was to examine whether a set of EOL care process measures mediated the association between Veteran race/ethnicity and bereaved families' overall rating of the quality of EOL care in VA medical centers (VAMCs). METHODS: A retrospective, cross-sectional analysis of linked Bereaved Family Survey (BFS), administrative and clinical data was conducted. The sample included 17,911 Veterans (mean age: 73.7; SD: 11.6) who died on an acute or intensive care unit across 121 VAMCs between October 2010 and September 2015. Mediation analyses were used to assess whether five care processes (potentially burdensome transitions, high-intensity EOL treatment, and the BFS factors of Care and Communication, Emotional and Spiritual Support, and Death Benefits) significantly affected the association between Veteran race/ethnicity and a poor/fair BFS overall rating. RESULTS: Potentially burdensome transitions, high-intensity EOL treatment, and the three BFS factors of Care and Communication, Emotional and Spiritual Support, and Death Benefits did not substantially mediate the relationship between Veteran race/ethnicity and poor/fair overall ratings of quality of EOL care by bereaved family members. CONCLUSIONS: The reasons underlying poorer ratings of quality of EOL care among bereaved family members of racial/ethnic minority Veterans remain largely unexplained. More research on identifying potential mechanisms, including experiences of racism, and the unique EOL care needs of racial and ethnic minority Veterans and their families is warranted.

OBJECTIVE: To compare characteristics of calls to the Veterans Crisis Line (VCL) by caller gender and identify potentially unique needs of women callers. METHOD: Retrospective review of clinical data collected during VCL calls, comparing call characteristics between women and men veteran callers. RESULTS: The data included 116,029 calls by women veterans and 651,239 calls by men veterans between January 1, 2018-December 31, 2019. Timing (hour/day/season) of VCL calls was similar between women and men callers. We observed gender differences in reason for call, with the most salient differences in reasons related to interpersonal violence, including sexual trauma (e.g., military sexual trauma as reason for call - prevalence ratio (PR) for women vs. men = 9.13, 95% CI = 8.83, 9.46). Women callers were also more likely than men callers to screen positive for suicide risk (PR = 1.28, 95% CI = 1.26, 1.29), receive a higher suicide risk assessment rating (PR = 1.05, 95% CI = 1.02, 1.07), and be referred to a VA Suicide Prevention Coordinator for follow-up (PR = 1.09, 95% CI = 1.09, 1.11). CONCLUSIONS: Analysis of VCL call data indicated both similarities and differences across genders in call characteristics, including interpersonal relationships and experiences of abuse and assault as particularly salient factors prompting women veterans' calls to VCL. This study also suggests the presence of increased suicide risk among women versus men veteran VCL callers.

ABSTRACT: The impact of preexposure prophylaxis uptake on sexual and injection-related behaviors among women who inject drugs is poorly understood. Over 24 weeks, preexposure prophylaxis uptake among women who inject drugs was associated with increased sharing of injection equipment but not syringes and no changes in condomless sex, providing limited evidence of risk compensation in this vulnerable population.

HIV and its treatment with antiretroviral therapy increase the risk of noncommunicable diseases (NCDs) tied to physical inactivity. Older African American men are also at high risk for NCDs. We tested the efficacy of a theory-based intervention to increase adherence to federal aerobic and muscle-strengthening physical activity (PA) guidelines among African American men aged 40 years and older living with HIV. We randomized African American men aged 40 years and older living with HIV to a three-session social cognitive theory-informed health promotion intervention targeting PA or a one-session health awareness control condition. The primary outcome was PA guideline adherence assessed (self-reported) preintervention, immediate postintervention, and 3, 6, and 12 months postintervention. Secondary outcomes were the number of days on which participants reported moderate-intensity aerobic PA, vigorous-intensity aerobic PA, and muscle-strengthening PA in the past 7 days. Of 302 participants, 255 completed the 12-month postintervention measures. Generalized estimated equation logistic regression indicated that the health promotion intervention participants had higher odds of meeting PA guidelines than health awareness control participants, adjusting for baseline adherence (p = 0.011). Health promotion intervention participants also reported more muscle-strengthening PA (p = 0.001), vigorous-intensity aerobic PA (p = 0.049), and moderate-intensity aerobic PA (p = 0.010) than control participants. The rise in self-reported adherence to PA guidelines and improvements in muscle-strengthening and aerobic PA considered separately suggest that a relatively brief behavioral intervention can increase PA among African American men aged 40 years and older living with HIV and potentially curb their risk of NCDs that PA can prevent.

Puerto Rico is a US territory and a popular destination for Latino immigrants in the Caribbean. Even with few language and cultural barriers, however, many Latino immigrants in Puerto Rico are uninsured. Using data from the 2014-19 Puerto Rico Community Survey, we examined inequities in health insurance coverage for non-Puerto Rican Latinos ages 18-64 living in Puerto Rico according to citizenship status and Latino subgroup (Dominican, Cuban, Mexican, and other Latino). After controlling for potential confounders, we found that noncitizen Dominicans had a significantly lower probability of having any health insurance (57.2 percent) and having any private insurance (31.5 percent). Regardless of similarities in culture and language, Latino immigrants on the island, particularly Dominicans, experience major health insurance coverage inequities. Considering that Puerto Rico's immigration system is regulated by US federal statute, both federal and local policy makers should acknowledge and focus on reducing these immigrant disparities in health insurance coverage.

Background Black Americans have a higher risk of hypertension compared with White Americans. Perceived discrimination is a plausible explanation for these health disparities. Few studies have examined the impact of perceived discrimination on the incidence of hypertension among a racially diverse sample. Our study examined associations of everyday and lifetime discrimination with incidence of hypertension and whether these associations varied by sex, discrimination attribution, and racial residential segregation. Methods and Results The study included 3297 Black, Hispanic, Chinese, and White participants aged 45 to 84 years from the Multi-Ethnic Study of Atherosclerosis who were without hypertension at exam 1 (2000-2002) and who completed at least 1 of 5 follow-up exams (2002-2018). Cox proportional hazards regression was used to estimate associations of perceived discrimination with incident hypertension. Over the follow-up period, 49% (n=1625) of participants developed hypertension. After adjustment for age, sex, socioeconomic status, hypertension risk factors, and study site, Black participants reporting any lifetime discrimination (compared with none) were more likely to develop hypertension (hazard ratio [HR], 1.35; 95% CI, 1.07-1.69). In fully adjusted models, everyday discrimination (high versus low) was associated with a lower risk for hypertension among Hispanic participants (HR, 0.73; 95% CI, 0.55-0.98). Statistically significant interactions of perceived discrimination (everyday and lifetime) with sex, discrimination attribution, and racial residential segregation were not observed. Conclusions This study suggests that lifetime, but not everyday discrimination is associated with incident hypertension in Black Americans.

Some women who inject drugs (WWID) would benefit from pre-exposure prophylaxis (PrEP), yet there are few studies of issues related to uptake in real-world settings. In this study, participants (n = 95) were offered PrEP and responded to items measuring PrEP-related attitudes, norms, and perceived behavioral control based on the Theory of Planned Behavior. We tested associations with intention to initiate PrEP and uptake. Most WWID (88%) intended to initiate PrEP and 78% accepted a prescription. Compared to WWID who did not express PrEP intentions, those who did were less concerned about attitudinal and perceived behavioral control constructs such as temporary (75% vs. 36%, p = 0.01) and long-term (63% vs. 27%, p = 0.05) side effects, negative interactions with their birth control (93% vs. 38%, p < 0.01), their ability to take a daily pill (80% vs. 36%, p < 0.01), and the cost of PrEP (87% vs. 36%, p < 0.01). WWID who went on to take PrEP had fewer concerns with subjective norms constructs such as talking to health care providers about sex (91% vs. 65%, p < 0.01) and drug use (88% vs. 55%, p < 0.01) compared to those who did not. Attitudes and perceived behavioral control influenced intention while subjective norms had a greater impact on actual uptake.

Little is known about how social networks among women who inject drugs (WWID) can be leveraged to increase awareness about pre-exposure prophylaxis (PrEP). We tested the hypothesis that interpersonal characteristics influence willingness of WWID to communicate PrEP information with peers. Forty WWID ≥ 18 years completed social network surveys. Participants named on average 9.3 (SD = 3.3) network members, resulting in 375 unique relationships. WWID were willing to share PrEP information with 83% of network members. Participants had higher odds of willingness to share information within relationships when the network member was female, homeless and perceived to be at risk for HIV. Among relationships with family members and transactional sex clients, stronger emotional closeness was associated with higher odds of willingness to share information. Peer interventions where WWID share PrEP information with peers may be an efficient approach to increase PrEP awareness among this vulnerable population.

INTRODUCTION: To guide future preexposure prophylaxis (PrEP) implementation for women who inject drugs (WWID), a population increasingly represented in new HIV cases in the United States, we present results from a demonstration project integrated within a syringe services program (SSP) in Philadelphia, PA. METHODS: WWID ≥18 years were educated about and offered 24 weeks of daily PrEP. Participants completed surveys and clinical assessments at baseline and at weeks 1, 3, 12, and 24. We used descriptive statistics to estimate feasibility/acceptability, engagement in the care cascade, HIV/sexually transmitted diseases (STI) and pregnancy, issues of safety/tolerability, and preferences/satisfaction with PrEP services. Multivariable logistic regression with generalized estimating equations was used to identify factors associated with PrEP uptake and retention. RESULTS: We recruited 136 WWID. Of those, 95 were included in the final sample, and 63 accepted a PrEP prescription at week 1. Uptake was associated with greater baseline frequency of SSP access [adjusted odds ratio (aOR) = 1.85; 95% confidence interval (CI): 1.24 to 2.77], inconsistent condom use (aOR = 3.38; 95% CI: 1.07 to 10.7), and experiencing sexual assault (aOR = 5.89; 95% CI: 1.02, 33.9). Of these 95, 42 (44.2%) were retained at week 24. Retention was higher among women who reported more frequent baseline SSP access (aOR = 1.46; 95% CI: 1.04 to 2.24). Self-reported adherence was high but discordant with urine-based quantification of tenofovir. Baseline STI prevalence was 17.9%; there were 2 HIV seroconversions and 1 pregnancy. Safety/tolerability issues were uncommon, and acceptability/satisfaction was high. CONCLUSIONS: Integrating PrEP with SSP services is feasible and acceptable for WWID. This suggests that daily PrEP is a viable prevention tool for this vulnerable population.

BACKGROUND AND OBJECTIVES: Evidence suggests that government expenditures on non-health care services can reduce infant mortality, but it is unclear what types of spending have the greatest impact among groups at highest risk. Thus, we sought to quantify how US state government spending on various services impacted infant mortality rates (IMRs) over time and whether spending differentially reduced mortality in some subpopulations. METHODS: A longitudinal, repeated-measures study of US state-level infant mortality and state and local government spending for the years 2000-2016, the most recent data available. Expenditures included spending on education, social services, and environment and housing. Using generalized linear regression models, we assessed how changes in spending impacted infant mortality over time, overall and stratified by race and ethnicity and maternal age group. RESULTS: State and local governments spend, on average, $9 per person. A $0.30 per-person increase in environmental spending was associated with a decrease of 0.03 deaths per 1000 live births, and a $0.73 per-person increase in social services spending was associated with a decrease of 0.02 deaths per 1000 live births. Infants born to mothers aged <20 years had the single greatest benefit from an increase in expenditures compared with all other groups. Increased expenditures in public health, housing, parks and recreation, and solid waste management were associated with the greatest reduction in overall IMR. CONCLUSIONS: Investment in non-health care services was associated with lower IMRs among certain high-risk populations. Continued investments into improved social and environmental services hold promise for further reducing IMR disparities.

BACKGROUND: Social comparison feedback is often used in physical activity interventions but the optimal design of feedback is unknown. METHODS: This 4-arm, randomized trial consisted of a 13-week intervention period and 13-week follow-up period. During the intervention, 4-person teams were entered into a weekly lottery valued at about $1.40/day and contingent on the team averaging ≥7000 steps per day. Social comparison feedback on performance was delivered weekly for 26 weeks, and varied by reference point (50th vs 75th percentile) and forgiveness in use of activity data (all 7 d or best 5 of 7 d). The primary outcome was the mean proportion of participant-days achieving the 7000-step goal. RESULTS: During the intervention period, the unadjusted mean proportion of participant-days that the goal was achieved was 0.47 (95% confidence interval [CI]: 0.38 to 0.56) in the 50th percentile arm, 0.38 (95% CI: 0.30 to 0.37) in the 75th percentile arm, 0.40 (95% CI: 0.31 to 0.49) in the 50th percentile with forgiveness arm, and 0.47 (95% CI: 0.38 to 0.55) in the 75th percentile with forgiveness arm. In adjusted models during the intervention and follow-up periods, there were no significant differences between arms. CONCLUSIONS: Changing social comparison feedback did not impact physical activity.

BACKGROUND: The use of medications to treat respiratory conditions of extreme prematurity is often based upon studies of adults or children over 2 years of age. Little is known about the spectrum of medications used or dosing ranges. To inform the design of future studies, we conducted a prospective analysis of respiratory medication exposure among 832 extremely low gestational age neonates. METHODS: The prematurity and respiratory outcomes program (PROP) enrolled neonates less than 29-week gestation from 6 centers incorporating 13 clinical sites. We collected recorded daily "respiratory" medications given along with dosing information through 40-week postmenstrual age or neonatal intensive care unit discharge if earlier. RESULTS: PROP participants were exposed to a wide range of respiratory medications, often at doses beyond published recommendations. Nearly 50% received caffeine and furosemide beyond published recommendations for cumulative dose. Those who developed bronchopulmonary dysplasia were more likely to receive treatment with respiratory medications. However, more than 30% of PROP subjects that did not develop bronchopulmonary dysplasia also were treated with diuretics, systemic steroids, and other respiratory medications. CONCLUSION: Extremely preterm neonates in PROP were exposed to high doses of medications at levels known to generate significant adverse effects. With limited evidence for efficacy, there is an urgent need for controlled trials in this vulnerable patient population.

BACKGROUND: Attrition, or loss to follow-up, presents a significant threat to the integrity and validity of longitudinal clinical research. Little is known about predictors of attrition in neonatal clinical research, and no prior studies have examined how families' experiences participating in research with their infants influences study compliance. OBJECTIVE: To identify novel factors that were associated with attrition over 1 year of study follow-up among preterm infants enrolled in the multicenter Prematurity and Respiratory Outcomes Program (PROP) observational study. METHODS: At discharge, research coordinators estimated the likelihood of attrition. The parents completed questionnaires about their experience with the study at discharge and at 1 year corrected age. The primary endpoint was completion of 4 PROP interviews during the first year. Logistic models were used to evaluate the associations between infant, family, and center-based characteristics and attrition. RESULTS: Among 318 children, 283 (89%) met the primary endpoint. In bivariate analyses, lower maternal education, more people in the household, public insurance, and site were associated with attrition (p < 0.05). Parent survey responses, infant characteristics, and site characteristics were unrelated to attrition. Coordinators' prediction of attrition was associated with completion of early study interviews; this effect waned over time. In multivariable analyses, lower maternal education and more people in the household were the factors most strongly associated with attrition. CONCLUSION: Future neonatal research should evaluate novel strategies to decrease the burden associated with study participation and reinforcement of study goals with families who have lower educational levels to facilitate participation and decrease attrition bias.

OBJECTIVE: To determine patterns of respiratory medications used in neonatal intensive care unit graduates. STUDY DESIGN: The Prematurity Respiratory Outcomes Program enrolled 835 babies <29 weeks of gestation in the first week. Of 751 survivors, 738 (98%) completed at least 1, and 85% completed all 4, postdischarge medication usage in-person/telephone parental questionnaires requested at 3, 6, 9, and 12 months of corrected age. Respiratory drug usage over the first year of life after in neonatal intensive care unit discharge was analyzed. RESULTS: During any given quarter, 66%-75% of the babies received no respiratory medication and 45% of the infants received no respiratory drug over the first year. The most common postdischarge medication was the inhaled bronchodilator albuterol; its use increased significantly from 13% to 31%. Diuretic usage decreased significantly from 11% to 2% over the first year. Systemic steroids (prednisone, most commonly) were used in approximately 5% of subjects in any one quarter. Inhaled steroids significantly increased over the first year from 9% to 14% at 12 months. Drug exposure changed significantly based on gestational age with 72% of babies born at 23-24 weeks receiving at least 1 respiratory medication but only 40% of babies born at 28 weeks. Overall, at some time in the first year, 55% of infants received at least 1 drug including an inhaled bronchodilator (45%), an inhaled steroid (22%), a systemic steroid (15%), or diuretic (12%). CONCLUSION: Many babies born at <29 weeks have no respiratory medication exposure postdischarge during the first year of life. Inhaled medications, including bronchodilators and steroids, increase over the first year.

BACKGROUND AND OBJECTIVE: Efavirenz is commonly used in Africa and is frequently associated with neurocognitive toxicity, which may compromise clinical outcomes. Older individuals are at increased risk for drug toxicity and clinical outcomes may be worse in older age, particularly among those individuals with cytochrome P450 (CYP) 2B6 polymorphisms associated with slower efavirenz metabolism. The aim of this study was to determine if the CYP2B6 polymorphisms differentially impacts loss to care in older people. METHODS: We conducted a prospective cohort study of 914 treatment-naïve HIV+ adults initiating efavirenz-based antiretroviral treatment at public HIV clinics in Gaborone, Botswana between 2009 and 2013. Older age, defined as age ≥ 50 years, was the primary exposure and loss to care at 6 months was the primary outcome. Interaction between age and CYP2B6 516G>T and 983T>C polymorphisms, defined as extensive, intermediate, and slow metabolism, was assessed. Neurocognitive toxicity was measured using a symptom questionnaire. Age-stratified logistic regression was performed to identify factors associated with loss to care. RESULTS: Older age was associated with loss to care (OR 1.95, 95% CI 1.30-2.92). Age modified the effect of CYP2B6 genotype on loss to care with older, slow metabolizers at over four-fold higher risk when compared to older, intermediate metabolizers (OR 4.06 95% CI 1.38-11.89); neurocognitive toxicity did not mediate this risk. CYP2B6 metabolism genotype did not increase risk of loss to care in younger participants. CONCLUSION: Older age was associated with loss to care, especially among those with slow efavirenz metabolism. Understanding the relationship between older age and CYP2B6 genotype will be important to improving outcomes in an aging population initiating efavirenz-based ART in similar settings.

Inter-individual variability in efavirenz (EFV) pharmacokinetics and dynamics is dominantly driven by the polymorphism in cytochrome P450 (CYP) isoenzyme 2B6 516G>T. We hypothesized that additional CYP polymorphisms mediate the relationship between CYP2B6 516G>T, EFV metabolism, and clinical events. We investigated 21 SNPs in 814 HIV-infected adults initiating EFV-based therapy in Botswana for population pharmacokinetics, CNS toxicities, and treatment outcomes. Two SNPs (rs28399499 and rs28399433) showed reduced apparent oral EFV clearance. Four SNPs (rs2279345, rs4803417, rs4802101, and rs61663607) showed extensive clearance. Composite CYP2B-mediated EFV metabolism was significantly associated with CNS toxicity (p = 0.04), with extensive metabolizers reporting more and slow and very slow metabolizers reporting less toxicity after 1 month compared to intermediate metabolizers. Composite CYP2B6 metabolism was not associated with composite early treatment failure. In conclusion, our data suggest that CNS-related toxicities might not be solely the result of super-therapeutic parent EFV concentrations in HIV-infected individuals in patients of African ancestry.

PURPOSE: To evaluate the effect of lottery-based financial incentives in increasing physical activity. DESIGN: Randomized, controlled trial. SETTING: University of Pennsylvania Employees. PARTICIPANTS: A total of 209 adults with body mass index ≥27. INTERVENTIONS: All participants used smartphones to track activity, were given a goal of 7000 steps per day, and received daily feedback on performance for 26 weeks. Participants randomly assigned to 1 of the 3 intervention arms received a financial incentive for 13 weeks and then were followed for 13 weeks without incentives. Daily lottery incentives were designed as a "higher frequency, smaller reward" (1 in 4 chance of winning $5), "jackpot" (1 in 400 chance of winning $500), or "combined lottery" (18% chance of $5 and 1% chance of $50). MEASURES: Mean proportion of participant days step goals were achieved. ANALYSIS: Multivariate regression. RESULTS: During the intervention, the unadjusted mean proportion of participant days that goal was achieved was 0.26 in the control arm, 0.32 in the higher frequency, smaller reward lottery arm, 0.29 in the jackpot arm, and 0.38 in the combined lottery arm. In adjusted models, only the combined lottery arm was significantly greater than control ( P = .01). The jackpot arm had a significant decline of 0.13 ( P < .001) compared to control. There were no significant differences during follow-up. CONCLUSIONS: Combined lottery incentives were most effective in increasing physical activity.
