RESUMEN

Importance: Sleep quality is a known marker of overall health. Studies suggest that adverse childhood experiences (ACEs) are associated with sleep disturbances among children and adults. Objective: To examine the association of retrospective and prospective ACEs with sleep quality among a cohort of Puerto Rican young adults from 2 sociocultural contexts. Design, Setting, and Participants: This prospective cohort study used data from the Boricua Youth Study (BYS), a population-based study representing Puerto Rican children from the South Bronx, New York, and Puerto Rico conducted from August 2000 to August 2003. Participants who were 5 to 9 years of age at enrollment in the BYS and who participated in wave 4 of the BYS took part in the Health Assessment (HA) when they were 18 to 29 years of age, from April 2013 to August 2017. Of the eligible 982 participants, 813 (82.8%) participated in the HA. Statistical analysis was conducted from January 2023 to January 2024. Exposures: Prospective ACEs measured from parent and youth responses and retrospective ACEs measured among young adults using questions from the validated ACE questionnaire from the original ACEs study conducted by Kaiser Permanente and the Centers for Disease Control and Prevention and published in 1998. Analysis included 8 overlapping items from both questionnaires. Outcomes: Sleep quality was assessed in the HA with the Pittsburgh Sleep Quality Index. The summary score included 7 components of the Pittsburgh Sleep Quality Index. The hypothesis was formulated after data collection. Sleep quality information was gathered at the same time as retrospective ACEs in the HA. Results: Of the 813 participants, 438 (53.9%) lived in Puerto Rico as children, 411 (50.6%) identified as female, and the mean (SE) age of participants was 22.9 (0.07) years. After adjusting for sociodemographic factors, retrospective ACEs had a significant association with worse sleep outcomes (ß [SE] = 0.29 [0.07]; 95% CI, 0.15-0.44; P < .001). Prospective ACEs did not have a significant association with sleep quality, after adjusting for sociodemographic factors (ß [SE] = 0.05 [0.10]; 95% CI, -0.14 to 0.24; P = .59). Conclusions and Relevance: This study suggests that there is a significant association between retrospective ACEs and sleep quality among Puerto Rican young adults, after adjusting for sociodemographic factors. Prospective ACEs were not significantly associated with sleep disturbances, after adjusting for sociodemographic factors. Addressing ACEs reported in young adulthood may help reduce sleep disorders.

RESUMEN

OBJECTIVE: To examine the association between changes in self-reported neighborhood stressors and sleep quality and determine whether this varied by sociocultural context among Puerto Rican young adults. METHODS: Data come from the Boricua Youth Study Health Assessment, a sample of Puerto Rican young adults from San Juan, Puerto Rico, and South Bronx, New York (n = 818; mean age=22.9years). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Neighborhood social stressors (disorder, social cohesion, and safety) were parent-reported in childhood and self-reported in young adulthood and categorized into: low in childhood/young adulthood (reference group), high in childhood/low in young adulthood, low in childhood/high in young adulthood, and high in childhood/young adulthood. Sociocultural context was based on participant residence during childhood (San Juan vs. South Bronx). RESULTS: Adjusting for sociodemographic factors, living with high neighborhood stressors in both childhood and young adulthood (prevalence ratios=1.30, 95% CI: 1.01, 1.66) was associated with overall poor sleep (PSQI score >5). Among PSQI components, living with high neighborhood stressors in young adulthood only or in both time periods was associated with worse subjective sleep quality and daytime dysfunction. Additionally, there were various associations between the neighborhood stressor measures and PSQI components. Results did not differ by sociocultural context. CONCLUSION: Findings suggest that living with high levels of neighborhood stressors during childhood and young adulthood may have a cumulative adverse impact on sleep quality in young adulthood.

RESUMEN

We describe and compare the prevalence of cardiometabolic risk factors and ideal cardiovascular health (CVH) among Puerto Rican young adults in the San Juan metro area in Puerto Rico and the South Bronx, NY. As part of the Boricua Youth Study - Health Assessment, (mean age 23 ± 0.1 years) objective anthropometric, blood pressure and blood samples were collected. Information on diet, physical activity and sleep were collected via surveys. Life's Essential 8 metrics were characterized as continuous with higher scores indicating more optimal CVH and categorically (80-100 scores for ideal CVH). Mean CVH score among NY participants was lower (61.9) than in PR (68.9). No participant had all ideal health metrics, 36% of participants in PR had 5 or more ideal CVH; while only 16% in NY met this criterion. The prevalence of cardiometabolic risk factors was high for obesity (35% in NY, 19% in PR) and diabetes (17% NY, 20% PR). In this ethnically homogenous population, we found low levels of ideal CVH that varied across study site, suggesting differences by sociocultural context. Interventions to maintain and improve CVH across the life course, tailored to sociocultural environments, are necessary for the prevention of cardiovascular disease.

RESUMEN

OBJECTIVE: Residents of Puerto Rico are disproportionately exposed to social and environmental stressors (e.g., Hurricane María and the 2020 sequence of tremors) known to be associated with psychological distress. Shift-and-persist (SP), or the ability to adapt the self to stressors while preserving focus on the future, has been linked with lower psychological distress, but no study has evaluated this in Puerto Rico. This study examined the association between SP and psychological distress (including that from natural disasters) in a sample of young adults in Puerto Rico. METHODS: Data from the Puerto Rico-OUTLOOK study (18-29 y) were used. Participants (n = 1497) completed assessments between September 2020 and September 2022. SP was measured with the Chen scale and categorized into quartiles (SPQ1-SPQ4). Psychological distress included symptoms of depression (CESD-10), anxiety (STAI-10), post-traumatic stress disorder (Civilian Abbreviated Scale PTSD checklist), and ataque de nervios (an idiom of distress used by Latinx groups). Outcomes were dichotomized according to clinical cutoffs when available, otherwise used sample-based cutoffs. Two additional items assessed the perceived mental health impact of Hurricane María and the 2020 sequence of tremors (categorized as no/little impact vs. some/a lot). Adjusted prevalence ratios (PR) and their 95% confidence intervals (CI) were estimated. RESULTS: The most commonly reported psychological distress outcome was PTSD (77%). In adjusted models, compared to SP Q1, persons in SP Q2-Q4 were less likely to have elevated symptoms of depression (PR Q2 = 0.79, 95% CI = 0.72-0.85; PR Q3 = 0.65, 95% CI = 0.58-0.73; and PR Q4 = 0.41, 95% CI = 0.35-0.48), PTSD (PR Q2 = 0.92, 95% CI = 0.87-0.98; PR Q3 = 0.86, 95% CI = 0.80-0.93; and PR Q4 = 0.76, 95% CI = 0.70-0.83), anxiety (PR Q2 = 0.39, 95% CI = 0.31-0.48; PR Q3 = 0.27, 95% CI = 0.20-0.37; and PR Q4 = 0.11, 95% CI = 0.07-0.17) and experiences of ataque de nervios (PR Q2 = 0.85, 95% CI = 0.76-0.94; PR Q3 = 0.79, 95% CI = 0.70-0.90; and PR Q4 = 0.68, 95% CI = 0.60-0.78). Compared to persons in SP Q1, persons in SP Q3-Q4 were less likely to report adverse mental health impacts from Hurricane María (PR Q3 = 0.66, 95% CI = 0.55-0.79; and PR Q4 = 0.53, 95% CI = 0.44-0.65) and the 2020 sequence of tremors (PR Q3 = 0.77, 95% CI = 0.61-0.98; and PR Q4 = 0.74, 95% CI = 0.59-0.94). CONCLUSION: SP was associated with lower psychological distress. Studies are needed to confirm our findings and evaluate potential mechanisms of action.

RESUMEN

OBJECTIVE: To examine how social deprivation and residential mobility are associated with primary care use in children seeking care at community health centers (CHCs) overall and stratified by race and ethnicity. STUDY DESIGN: We used electronic health record open cohort data from 152 896 children receiving care from 15 U S CHCs belonging to the OCHIN network. Patients were aged 3-17 years, with ≥2 primary care visits during 2012-2017 and had geocoded address data. We used negative binomial regression to calculate adjusted rates of primary care encounters and influenza vaccinations relative to neighborhood-level social deprivation. RESULTS: Higher rates of clinic utilization were observed for children who always lived in highly deprived neighborhoods (RR = 1.11, 95% CI = 1.05-1.17) and those who moved from low-to-high deprivation neighborhoods (RR = 1.05, 95% CI = 1.01-1.09) experienced higher rates of CHC encounters compared with children who always lived in the low-deprivation neighborhoods. This trend was similar for influenza vaccinations. When analyses were stratified by race and ethnicity, we found these relationships were similar for Latino children and non-Latino White children who always lived in highly deprived neighborhoods. Residential mobility was associated with lower rates of primary care. CONCLUSIONS: These findings suggest that children living in or moving to neighborhoods with high levels of social deprivation used more primary care CHC services than children who lived in areas with low deprivation, but moving itself was associated with less care. Clinician and delivery system awareness of patient mobility and its impacts are important to addressing equity in primary care.

RESUMEN

Religiosity may influence COVID-19 vaccination. However, it remains unclear how religiosity is associated with beliefs toward COVID-19 and vaccination against it, particularly amongst ethnic minorities. This study examined the association between religiosity, vaccination intent, beliefs, and attitudes related to COVID-19 and vaccination among adults in Puerto Rico. Data from an online survey conducted between December 2020-February 2021 among adults (≥18 yr; n = 1895) residing in Puerto Rico were used. Rating of the importance of religiosity was used to capture the level of religiosity ('less important', 'somewhat important', 'important', and 'very important'). The health belief model (HBM) assessed beliefs and attitudes toward COVID-19 and vaccination against it. Adjusted Poisson models with robust error variance estimated prevalence ratios (PR) and 95% confidence intervals for vaccination intent and individual COVID-19 HBM constructs. Compared to individuals rating religiosity as 'less important' to them, those rating it as 'very important' were more likely to be unwilling or uncertain to get the COVID-19 vaccine (PR = 1.51, 95% CI = 1.10-2.05). Higher ratings of importance of religiosity, compared to the lowest level, were associated with significantly lower perceived COVID-19 susceptibility, more vaccine barriers, and lower vaccine benefits (all p < 0.05). Individuals who reported religiosity being very important to them were more likely to report that they will get the COVID-19 vaccine only if given adequate information about it (PR = 1.14, 95% CI = 1.02-1.27) and more likely to get the vaccine if more people decide to receive it (all p < 0.05). In conclusion, our results suggest an association between religiosity and COVID-19 vaccination intent and beliefs and attitudes toward vaccination. The study highlights important guidelines for public health campaigns to increase vaccine uptake among religious communities in Puerto Rico.

RESUMEN

OBJECTIVE: To test whether a policy approach aimed at decreasing prescription drug misuse, specifically, state monitoring of controlled substance prescriptions-prescription drug monitoring programs (PDMPs)-were associated with changes in Child Protective Services-reported maltreatment prevalence. STUDY DESIGN: Using a difference-in-differences design and maltreatment data (2004-2018) from 50 states and the District of Columbia, we compared the prevalence of total maltreatment incidents and total victims, in states with and without PDMPs, before and after implementation. Exploratory analyses further examined models disaggregated by maltreatment type (neglect, physical abuse, sexual abuse, psychological abuse) and among different racial/ethnic groups. Quasi-Poisson models included state-level covariates, state- and year-fixed effects, and cluster-robust standard errors. RESULTS: Difference-in-differences models identified greater relative reductions in PDMP states relative to controls (total prevalence ratio, 0.87; 95% CI, 0.80, 0.940; victimization prevalence ratio, 0.92; 95% CI, 0.85-0.98) over the observation period. Decreases seemed to be driven by changes in neglect (prevalence ratio, 0.87; 95% CI, 0.80-0.93) and physical abuse (prevalence ratio, 0.78; 95% CI, 0.71-0.87) incidents, and may have been especially salient for American Indian/Alaskan Native children (prevalence ratio, 0.78; 95% CI, 0.65-0.94). CONCLUSIONS: We found evidence supporting an association between prescription drug monitoring and reduced maltreatment prevalence at the state level. Policies aimed at restricting the prescribing and dispensing of controlled substances may have indirect implications for child welfare.

RESUMEN

BACKGROUND: Exposure to childhood adversities (CA) is associated with sleep disturbances; however, evidence has largely been drawn from cross-sectional data and has not addressed the relationship across developmental stages. Also, most studies have primarily focused on non-Hispanic White cohorts with a dearth of longitudinal evidence about racial/ethnic minorities. We examined the longitudinal association between CA and sleep disturbances in Puerto Rican youth. METHOD: The Boricua Youth Study is a longitudinal study of Puerto Rican youth living in San Juan, Puerto Rico, and the South Bronx, NY (N = 2491). Among youth 5-9 and 10-16 years old, sleep disturbances were assessed through three yearly interviews. Lifetime exposure to CA included parental loss, child maltreatment, parental maladjustment, and exposure to violence. Weighted generalized linear mixed models examined the longitudinal association between CA and sleep disturbances in youth adjusting for sociodemographic and contextual covariates. RESULTS: The prevalence of sleep disturbances was similar in both age groups (ages 5-9 and 10-16). In multivariable mixed models, CA were associated with sleep disturbance across three Waves among 10-16-year-olds. For example, having 2-3 or ≥ 4 types of CA were related to a higher prevalence of trouble falling/staying asleep in models adjusting for social context, gender, welfare status, or mother's education. No associations were observed among 5-9-year-olds. CONCLUSION: The results suggest that cumulative adversities in childhood may lead to sleep problems in adolescence. These findings highlight the utility of addressing CA during childhood to help reduce sleep-wake disorders throughout adolescence, a known risk factor for future mental and physical health problems.

RESUMEN

OBJECTIVE: Evidence stemming largely from retrospective studies suggests that childhood adversity (CA) is associated with earlier age at menarche, a marker of pubertal timing, among girls. Little is known about associations with pubertal tempo among boys or racial/ethnic minorities. We examined the association between CA and timing and tempo of pubertal development among boys and girls. METHODS: The Boricua Youth Study is a longitudinal study of Puerto Rican youth residing in the San Juan metro area in Puerto Rico and the South Bronx, New York. CA was based on caretaker reports of parental loss and parental maladjustment and youth reports of child maltreatment and exposure to violence. Youth completed the Pubertal Development Scale (PDS) yearly for 3 years. In linear mixed models stratified by sex, we examined the association between CA and pubertal timing and tempo, adjusting for site, socioeconomic status, and age. RESULTS: Among the 1949 children who were 8 years or older by wave 3, cumulative CA was associated with higher PDS scores among girls compared with girls not exposed to CA (PDS score: 2.63 [95% confidence interval {CI} = 2.55-2.71] versus 2.48 [95% CI = 2.37-2.58]). In contrast, among boys, experiencing adversities was associated with lower pubertal developmental stage or later timing (PDS: 1.77 [95% CI = 1.67-1.87] versus 1.97 [95% CI = 1.85-2.10]) compared with those not exposed to adversities. CONCLUSIONS: Associations between CA and pubertal development may vary by sex. Understanding the etiological role of adversities on pubertal development and identifying targets for intervention are of utmost importance in ameliorating the impact of CA on child health.

RESUMEN

Among maltreated children, elevated use of non-routine (for illness or injury) services may coexist with underutilization of preventive services. Besides physical health problems, lack of contact with primary care may preclude the identification and delivery of appropriate interventions. We examined health service utilization in the longitudinal Boricua Youth Study of Puerto Rican children residing in the South Bronx (SBx), New York City ( n = 901), and San Juan metropolitan area, Puerto Rico ( n = 1,163). Parents and children ( Mage = 9 years) reported on child physical abuse, sexual abuse, and neglect. Parents reported if their child had been to illness, injury, and well-child visits in the past year. In the SBx site, caretakers were more likely to report the children seeing a doctor for a well-child visit (90%) compared with children in Puerto Rico (71%). Children in Puerto Rico were more likely to visit a doctor for an injury in the past year compared with children in the SBx (39% vs. 24%). Twenty-one percent of children in the SBx reported maltreatment versus 16% in Puerto Rico. Adjusting for sociodemographic factors, compared with non-maltreated children, those who experienced two or more types of maltreatment were more likely to have an illness visit in Puerto Rico (prevalence ratio [PR] = 1.5, 95% confidence interval [CI] = [1.1, 2.2]) and the SBx (PR = 1.8, 95% CI = [1.1, 3.0]), or an injury visit (PR = 4.1, 95% CI = [1.9, 8.9]) in Puerto Rico only. Children in the SBx who reported only one type of maltreatment were less likely to use services for injuries than non-maltreated children (PR = 0.42, 95% CI = [0.2, 0.9]). No relation between maltreatment and well-child visits was noted. Children who experience maltreatment may frequently come in contact with health care providers, presenting opportunities for intervention and the prevention of further maltreatment.

RESUMEN

OBJECTIVES: To examine the association between short sleep duration and obesity among adolescents (mean age 16 years) transitioning into young adulthood (mean age 21 years) in the National Longitudinal Study of Adolescent Health (N = 10,076). STUDY DESIGN: Self-reported sleep duration was categorized as <6, 6-8, or >8 hours. Obesity status, using measured height and weight, was defined as body mass index ≥95th percentile in adolescence and body mass index ≥30 kg/m(2) in young adulthood. RESULTS: Cross-sectionally, short sleep duration was associated with obesity in adolescent males (prevalence ratio 1.8 [95% CI, 1.3-2.4]) but not in females (prevalence ratio 1.0 [95% CI, 0.7-1.4]). In longitudinal analyses, short sleep duration in adolescence was associated with incident obesity in both males and females (risk ratio 1.2 [95% CI, 1.0-1.6]) in young adulthood. No interactions by sex were noted. CONCLUSIONS: Analyzing the association of sleep duration and obesity longitudinally resolved sex discrepancies observed in earlier cross-sectional analyses. Optimizing sleep duration during adolescence may be an effective intervention to prevent excess weight gain in young adults.

RESUMEN

OBJECTIVE: To examine soda consumption and aggressive behaviors, attention problems, and withdrawal behavior among 5-year-old children. STUDY DESIGN: The Fragile Families and Child Wellbeing Study is a prospective birth cohort study that follows a sample of mother-child pairs from 20 large US cities. Mothers reported children's behaviors using the Child Behavior Checklist at age 5 years and were asked to report how many servings of soda the child drinks on a typical day. RESULTS: In the sample of 2929 children, 52% were boys, 51% were African-American, 43% consumed at least one serving of soda per day, and 4% consumed 4 or more servings per day. In analyses adjusted for sociodemographic factors, consuming one (beta, 0.7; 95% CI, 0.1-1.4), 2 (beta, 1.8; 95% CI, 0.8-2.7), 3 (beta, 2.0; 95% CI, 0.6-3.4), or 4 or more (beta, 4.7; 95% CI, 3.2-6.2) servings was associated with a higher aggressive behavior score compared with consuming no soda. Furthermore, those who consumed 4 or more (beta, 1.7; 95% CI, 1.0-2.4) soda servings had higher scores on the attention problems subscale. Higher withdrawn behavior scores were noted among those consuming 2 (beta, 1.0; 95% CI, 0.3-1.8) or 4 or more (beta, 2.0; 95% CI, 0.8-3.1) soda servings compared with those who consumed no soda. CONCLUSION: We note an association between soda consumption and negative behavior among very young children; future studies should explore potential mechanisms that could explain this association.
