OBJECTIVE: A growing evidence base suggests home and neighborhood environmental exposures may influence adolescent sleep, but few studies have assessed these relationships using methods that account for time-varying, location-specific exposures, or multiple neighborhood contexts. This study aimed to assess the feasibility and acceptability of using smartphone global positioning system (GPS) tracking and ecological momentary assessment (EMA) to assess time-varying home and neighborhood environmental exposures hypothesized to be associated with adolescent sleep.

METHODS: Adolescents aged 15-17 years in Philadelphia completed 7 days of continuous smartphone GPS tracking, which was used to identify daily levels of exposure to geocoded neighborhood factors (eg, crime, green space). Four daily EMA surveys assessed home sleep environment (eg, noise, light), stress, health behaviors, and neighborhood perceptions. Feasibility and acceptability of GPS tracking and EMA were assessed, and distributions of daily environmental exposures were examined.

RESULTS: Among 25 teens (mean age 16, 56% male), there was a high level of GPS location data captured (median daily follow-up: 24 hours). Seventy-eight percent of EMA surveys were completed overall. Most participants (96%) reported no privacy concerns related to GPS tracking and minimal burden from EMA surveys. Exposures differed between participants' home neighborhoods and locations visited outside the home neighborhood (eg, higher crime away from home). Sleep environment disruptions were present on 29% of nights (most common: uncomfortable temperature) and were reported by 52% of adolescents.

CONCLUSIONS: Results demonstrate the feasibility and acceptability of mobile methods for assessing time-varying home and neighborhood exposures relevant to adolescent sleep for up to 1 week.

BACKGROUND: Chronic parental stress may negatively impact health among both parents and children. Adverse neighborhood social conditions like crime may increase stress while a supportive neighborhood may buffer stress and promote well-being. Our objective was to examine associations between neighborhood social factors and stress among mothers of young children.

METHODS: We surveyed 300 mothers/female caregivers of Medicaid-enrolled 2 to 4-year-old children in Philadelphia. Maternal stress was measured via the 10-item Perceived Stress Scale (range 0-40). Mothers' perceived neighborhood safety and collective efficacy were assessed using validated scales. Addresses were geocoded to link census tract-level violent crime rates. We used multivariable linear regression to examine associations of neighborhood safety, collective efficacy, and crime with maternal stress, adjusted for demographics, household socioeconomic status, and neighborhood poverty.

RESULTS: Among mothers (mean age 31, 60% Black/African American), higher perceived neighborhood safety and collective efficacy were associated with lower stress scores after adjustment for covariates. Each 1-point increase (on a 5-point scale) in perceived neighborhood safety was associated with a 2.30-point decrease in maternal stress (95% CI: -3.07, -1.53). Similarly, each 1-point increase in perceived collective efficacy was associated with a 3.08-point decrease in maternal stress (95% CI: -4.13, -2.02). Police-recorded violent crime rates were not associated with maternal stress.

CONCLUSION: Mothers of young children who perceive their neighborhood social environment more favorably report less stress compared to those who feel their neighborhood environment is less safe and cohesive. Future work is warranted to investigate whether interventions that increase perceived neighborhood safety and collective efficacy reduce stress.

Food insecurity has myriad associations with poor health, and low-income communities have higher than average prevalence of food insecurity. Living in a supportive neighborhood social environment may protect against food insecurity, while adverse neighborhood social conditions, such as crime, may increase the likelihood of food insecurity. To examine associations between food insecurity and neighborhood social factors among families with young children, we administered a cross-sectional survey to 300 mothers and female caregivers of Medicaid-enrolled two- to four-year-old children in Philadelphia. We used multivariable regression to examine associations between food insecurity and perceived neighborhood safety, social cohesion, informal social control, and crime, adjusted for demographics, socioeconomic status, and neighborhood characteristics. Lower food insecurity prevalence was associated with higher perceived neighborhood safety and social cohesion, and lower police-recorded violent crime rates. Future work to increase food security among low-income households may benefit from targeting the neighborhood social environment.

<p>Positive neighborhood environments may promote healthier behaviors, yet few studies have examined associations between neighborhood social environment and diet. We examined associations of neighborhood perceived safety, collective efficacy, and violent crime with dietary intake among preschool-aged children and their mothers. We administered a cross-sectional survey to 300 mothers/female caregivers of Medicaid-enrolled 2- to 4-year-old children in Philadelphia. Mothers reported their own and their child's dietary intake using the validated Dietary Screener Questionnaire. Mixed-effects linear regression models assessed associations of perceived neighborhood safety, collective efficacy, and census tract-level violent crime with parent and child dietary intake, adjusted for individual, family, and neighborhood covariates. Among mothers, higher perceived neighborhood safety and collective efficacy were associated with higher daily intake of fruits/vegetables (β = 0.35 cups, 95% CI: 0.12-0.58 and β = 0.30 cups, 95% CI: 0.08-0.52, comparing the highest with lowest tertile). Higher neighborhood-perceived safety was also associated with higher whole-grain intake among mothers (β = 0.14 ounces, 95% CI: 0.02-0.27) and children (β = 0.07 ounces, 95% CI: 0.01-0.13, comparing the highest with lowest tertile). Neighborhood social exposures were not associated with intake of added sugars or sugar-sweetened beverages for mothers or children, nor were lower levels of violent crime associated with any outcome. More favorable perceptions of neighborhood safety and collective efficacy were associated with a slightly higher consumption of some healthy foods among mothers and their young children. Future prospective research is needed to confirm these findings, explore potential mechanisms, and determine whether intervening on the social environment improves diet.</p>
