Muscle strength during pregnancy and postpartum in adolescents and adults.

Adolescent childbirth is associated with worse physical function over the long-term. Differential loss of muscle strength during pregnancy and postpartum for adolescents compared to adults may be one explanation for this, but research examining these differences is lacking. The objective of this study as to assess hand grip strength and hip adduction muscle strength in adolescents and adults during pregnancy and postpartum. A prospective cohort study was carried out with adolescent (13 to 18 years) and adult (23 to 28 years) primigravid women. Assessments were performed at three timepoints: before the 16th gestational week, during the third trimester, and between the fourth and sixth week postpartum. Hand grip strength (continuous and muscle weakness if ≤ 20.67 kgf) and hip adductor measures (continuous and muscle weakness if ≤ 13.8 kgf) were assessed using dynamometry. Generalized estimating equations modelled longitudinal relationships between muscle weakness and age group. More adolescents had hip adductor weakness than adults in the third trimester of pregnancy (62.5% vs. 31.8%, p < 0.005), which was corroborated by the longitudinal analyses. For all women, there were higher odds of hip adductor weakness in the third trimester (OR = 4.35; p< 0.001) and postpartum (OR = 9.45; p < 0.001) compared to the 16th gestational week. No significant difference in HGS was observed between age groups or across the different timepoints. The higher proportion of hip adductor weakness among adolescents may indicate a need for resistance training during and after pregnancy and physical therapy if weakness or injury is noted.

Examining Mental Health and Economic Consequences During the COVID-19 Pandemic Among Filipino Residents in Hawai'i: May - Oct 2020.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in rapid and drastic changes to daily lives, posing a threat to residents' mental health and well-being. Filipinos are disproportionately impacted by COVID-19 and have one of the highest COVID-19 prevalence in Hawai'i. The COVID-19 pandemic has been associated with a rise in mental health concerns, yet little is known about the impact on the mental health of Filipinos in Hawai'i. Using publicly available polling data from the SMS Community Pulse Survey, this study sought to describe the mental distress experienced by Filipino residents during the COVID-19 pandemic. Data were collected from an online panel of Hawai'i residents over 4 timepoints (May 5-10; June 11-17; July 31-August 8; October 19-31, 2020). Compared to non-Filipinos, a higher proportion of Filipinos reported feeling stress and sadness during 3 of the 4 timepoints. Across all timepoints, Filipinos were more likely to respond affirmatively to mental health indicators (62.5%). Similarly, Filipinos reported food insecurity in higher proportions relative to non-Filipinos in most timepoints, particularly notable in Timepoint 4 where 33.0% of Filipino respondents reported food insecurity. These findings suggest that Filipinos would benefit from social policy and community-supported initiatives to address social determinants of health, reduce chronic stress, and prevent further mental health disparities.

Microplastics absent from reef fish in the Marshall Islands: Multistage screening methods reduced false positives.

Island communities, like the Republic of the Marshall Islands (RMI), depend on marine resources for food and economics, so plastic ingestion by those resources is a concern. The gastrointestinal tracts of nine species of reef fish across five trophic groups (97 fish) were examined for plastics >1 mm. Over 2100 putative plastic particles from 72 fish were identified under light microscopy. Only 115 of these from 47 fish passed a plastic screening method using Fourier-transform infrared microspectroscopy (µFTIR) in reflectance mode. All of these were identified as natural materials in a final confirmatory analysis, attenuated total reflectance FTIR. The high false-positive rate of visual and µFTIR methods highlight the importance of using multiple polymer identification methods. Limited studies on ingested plastic in reef fish present challenging comparisons because of different methods used. No plastic >1 mm were found in the RMI reef fish, reassuring human consumers.

Real-World Evaluation of an Automated Algorithm to Detect Patients With Potentially Undiagnosed Hypertension Among Patients With Routine Care in Hawai'i.

BACKGROUND: This real-world evaluation considers an algorithm designed to detect patients with potentially undiagnosed hypertension, receiving routine care, in a large health system in Hawai'i. It quantifies patients identified as potentially undiagnosed with hypertension; summarizes the individual, clinical, and health system factors associated with undiagnosed hypertension; and examines if the COVID-19 pandemic affected detection. METHODS AND RESULTS: We analyzed the electronic health records of patients treated across 6 clinics from 2018 to 2021. We calculated total patients with potentially undiagnosed hypertension and compared patients flagged for undiagnosed hypertension to those with diagnosed hypertension and to the full patient panel across individual characteristics, clinical and health system factors (eg, clinic of care), and timing. Modified Poisson regression was used to calculate crude and adjusted risk ratios. Among the eligible patients (N=13 364), 52.6% had been diagnosed with hypertension, 2.7% were flagged as potentially undiagnosed, and 44.6% had no evidence of hypertension. Factors associated with a higher risk of potentially undiagnosed hypertension included individual characteristics (ages 40-84 compared with 18-39 years), clinical (lack of diabetes diagnosis) and health system factors (clinic site and being a Medicaid versus a Medicare beneficiary), and timing (readings obtained after the COVID-19 Stay-At-Home Order in Hawai'i). CONCLUSIONS: This evaluation provided evidence that a clinical algorithm implemented within a large health system's electronic health records could detect patients in need of follow-up to determine hypertension status, and it identified key individual characteristics, clinical and health system factors, and timing considerations that may contribute to undiagnosed hypertension among patients receiving routine care.

Adolescent childbirth and mobility disability among women ages 15-49: an analysis of population health surveys from 14 low-income and middle-income countries.

OBJECTIVES: Adolescent childbirth is associated with older adult adverse health outcomes that negatively affect mobility function, but these associations have not been studied globally in large samples of reproductive-age women. This study examines the association between age at first childbirth and mobility disability in national surveys from low-income and middle-income countries, and hypotheses that adolescent childbirth is associated with mobility disability. DESIGN: Cross-sectional analysis. SETTING: Population health surveys from 2013 to 2018 containing mobility disability measures among ever-pregnant women ages 15-49. These included 13 Demographic Health Surveys from Haiti, Pakistan, Uganda, Cambodia, Colombia, South Africa, Timor-Leste, Albania, Gambia, Maldives, Peru, Senegal and Yemen and 1 Maternal Health Survey from Ghana. PARTICIPANTS: The sample included 157 988 women ages 15-49 years. PRIMARY OUTCOME MEASURE: Adolescent childbirth was defined as 10-19 years of age. Poisson regression models were used to estimate prevalence ratios (PRs) of mobility disability among women who first gave birth during adolescence and in adult life (ages 20-45 years) in each country and across the whole sample. Countries were also analysed according to the use of standard and non-standard mobility disability measures. Covariates included current age, urban/rural residence, education and household wealth. RESULTS: Prevalence of adolescent childbirth (17.5%-66.2%) and mobility disability (0.32%-21.45%) varied widely across countries. Adolescent childbirth was significantly (p<0.05) associated with greater mobility disability in six of eight countries using standard disability measures. Among the six countries that did not use standard disability measures, none showed a statistically significant association between adolescent childbirth and mobility disability. Considering the whole sample and adjusting for all covariates, women who gave birth during adolescence had greater prevalence of mobility disability (pooled PR 1.19, 95% CI 1.06-1.31). CONCLUSIONS: This analysis suggests a moderate and consistent association of adolescent childbearing with subsequent mobility disability.

Culturally Relevant Physical Activity in the Behavioral Risk Factor Surveillance System in Hawai'i.

INTRODUCTION: Culturally relevant physical activity is a promising field for chronic disease prevention and management. Native Hawaiians and Other Pacific Islanders have higher rates of physical inactivity than other racial or ethnic groups and increased risk of chronic disease. The study objective was to provide population-level data from Hawai'i on lifetime experiences in the Native Hawaiian Indigenous practices of hula and outrigger canoe paddling across demographic and health factors to identify opportunities for public health intervention, engagement, and surveillance. METHODS: Questions about hula and paddling were added to the Hawai'i 2018 and 2019 Behavioral Risk Factor Surveillance System (N = 13,548). We considered level of engagement by demographic categories and health status indicators, accounting for the complex survey design. RESULTS: Overall, 24.5% of adults engaged in hula and 19.8% in paddling in their lifetime. Prevalence of engagement was higher among Native Hawaiians (48.8% hula, 41.5% paddling) and Other Pacific Islanders (35.3% hula, 31.1% paddling) than among other racial and ethnic groups. In adjusted rate ratios, experience in these activities was strong across age groups, education, sex, and income levels, particularly among Native Hawaiians and Other Pacific Islanders. CONCLUSION: Throughout Hawai'i, hula and outrigger canoe paddling are important and popular cultural practices with high physical activity demands. Participation was notably high for Native Hawaiians and Other Pacific Islanders. Surveillance information around culturally relevant physical activities can benefit public health programming and research from a strength-based community perspective.

Socioecological Factors Associated with Hypertension Awareness and Control Among Older Adults in Brazil and Colombia: Correlational Analysis from the International Mobility in Aging Study.

Background: Hypertension awareness and control are understudied among older adults in middle-income countries, with limited work contextualizing awareness and control across layers of influence (individual to the community). Research on hypertension in Latin America is acknowledged as insufficient. Objectives: This study applies the socioecological model (SEM) to examine individual, interpersonal, institutional, and community factors related to hypertension awareness and control in older adults residing in Brazil and Colombia. It identifies groups of older adults more likely to be unaware of their condition and/or to have challenges achieving hypertension control. Methods: We analyzed International Mobility in Aging Study data of 803 community-dwelling adults 65-74 years from study sites in the two most populous countries in South America. The study framework was the socioecological model. Logistic regression models identified factors associated with hypertension awareness and control. Conclusions: Hypertension was prevalent in both samples (>70%), and awareness was high (>80%). Blood pressure control among diagnosed respondents was low: 30% in Brazil and 51% in Colombia. Factors across the socioecological model were associated with awareness and control, with notable differences across countries. Those with diabetes (OR 4.19, 95%CI 1.64-10.71) and insufficient incomes (OR: 1.85, 95%CI 1.03-3.31) were more likely to be aware of their hypertension. In Colombia, those reporting no community activity engagement were less likely to be aware compared to those reporting community activities. In Brazil, it was the opposite. Women (OR 1.66, 95%CI 1.12-2.46) and those reporting strolling shops and stores (OR 1.80, 95% CI 1.09-3.00) were significantly more likely to have their hypertension under control. In Brazil, those 70-75 were significantly less likely to have their hypertension under control compared to their younger counterparts. In Colombia, this was not observed. This paper highlights the importance of theory-based studies within unique Latin American contexts on hypertension and suggests novel opportunities for intervention.

Intersections between adolescent fertility and obesity-pathways and research gaps focusing on Latin American populations.

Latin America has notably elevated rates of adolescent fertility and obesity in women. Although numerous studies document associations between adolescent fertility and obesity across the life course, the pathways explaining their association are insufficiently theorized, especially regarding the factors in Latin America that may underpin both. Additionally, much of the existing research is from high-income countries, where fertility and obesity are trending down. In this paper, we review the various complex pathways linking adolescent fertility and obesity, highlighting research gaps and priorities, with a particular focus on Latin American populations. We carefully consider pregnancy's distinct impact on growth trajectories during the critical period of adolescence, as well as the cumulative effect that adolescent fertility may have over the life course. We also articulate a pathway through obesity as it may contribute to early puberty and thus, to adolescent fertility. If obesity is a cause of adolescent fertility, not a result of it, or if it is a mediator of early-life exposures to adulthood obesity, these are critical distinctions for policy aiming to prevent both obesity and early fertility. Research to better understand these pathways is essential for prevention efforts against obesity and undesired adolescent fertility in Latin America.

Total Hemoglobin Trajectories from Pregnancy to Postpartum in Rural Northeast Brazil: Differences between Adolescent and Adult Women.

This study examines total hemoglobin (THB) trajectories during pregnancy and postpartum and associated factors among adolescents and adults from a low-income community. This is an observational, longitudinal study, part of the Adolescence and Motherhood Research (AMOR) project, performed between 2017 and 2019 in the Trairi region of Rio Grande do Norte state, Brazil. The THB levels of 100 primigravida adolescents and adults were monitored up to 16 weeks of gestation, in the third trimester, and 4-6 weeks postpartum, along with socioeconomic characteristics, anthropometrics, and health-related variables. Mixed-effect linear models evaluated the trajectories of THB and the associated factors. THB levels decreased between first and second assessments and increased between the second and postpartum assessments. For the adolescent cohort, the rebound in THB concentration between the third trimester and postpartum was not enough to make up for the initial losses, as occurred in the adult cohort. For the adult group, higher THB levels were associated with pregnancy planning and good self-rated health. Race was marginally associated to THB levels, with black/brown women presenting higher concentrations in the adolescent and lower concentration in the adult group. Special attention to prenatal care among pregnant adolescents should consider their higher risk of anemia and its negative effects.

Modifiable Factors and Incident Gout Across Ethnicity Within a Large Multiethnic Cohort of Older Adults.

OBJECTIVE: Gout disproportionately affects older Pacific Islander and Black populations relative to White populations. However, the ethnic-specific determinants remain understudied within these groups, as well as within other ethnicities. We examined gout incidence and associations with behavioral factors, including diet, alcohol, and smoking, within a large multiethnic population of older adults from the Multiethnic Cohort Study, which linked prospective cohort data to Medicare gout claims between 1999-2016. METHODS: Using samples of Black (n = 12,370), Native Hawaiian (n = 6459), Japanese (n = 29,830), Latino (n = 17,538), and White (n = 26,067) participants, we conducted multiple Cox regressions, producing hazard ratios (HRs) and 95% CIs. RESULTS: Relative to White individuals, Native Hawaiians had the highest risk of gout (HR 2.21, 95% CI 2.06-2.38), followed successively by Black and Japanese participants, whereas Latino individuals had a lower risk of gout (HR 0.78, 95% CI 0.73-0.83). Alcohol use was associated with an increased risk, with significantly greater effects observed among Japanese participants drinking ≥ 3 drinks per day (HR 1.46, 95% CI 1.27-1.66), or > 5 beers per week (HR 1.29, 95% CI 1.17-1.43), compared to White individuals (Pinteraction < 0.001). Former smokers with ≥ 20 pack-years had an increased risk (HR 1.14, 95% CI 1.06-1.22). Higher dietary quality was associated with a decreased gout risk, with the largest effect observed among White participants (HRQ5vsQ1 0.84, 95% CI 0.79-0.90), whereas vitamin C was weakly associated with a decreased risk of gout only among Japanese individuals (HR 0.91, 95% CI 0.85-0.98). CONCLUSION: Overall, notable ethnic differences were observed in both gout risk and associations with modifiable behavioral factors. Our findings offer crucial insights that may improve precision in preventing and managing gout.

Identifying best practices in adoption, implementation and enforcement of flavoured tobacco product restrictions and bans: lessons from experts.

OBJECTIVE: To identify recommended components for adopting, implementing and enforcing bans or restrictions targeting flavoured tobacco products. METHODS: Between April and June 2019, semistructured interviews were conducted with 17 high-level experts across the USA and Canada with expertise in flavoured tobacco product policies. Participants included health department staff, researchers, legal professionals and local government officials. Interviews were recorded, transcribed and analysed for key themes. RESULTS: Major findings were organised into four categories: programme planning and legislative preparations; education and community outreach; implementation and enforcement; and policy impact. Critical pre-implementation elements included using comprehensive policy language, identifying enforcement agents, examining potential economic costs, deploying media campaigns and engaging community partners and retailers. Recommended implementation processes included a 6-month preparation timeline, focus on retailer education and clearly outlined enforcement procedures, particularly for concept flavours. CONCLUSIONS: Flavoured tobacco policies have successfully limited sales, withstood legal challenges and become more comprehensive over time, providing useful lessons to inform ongoing and future legislative and programmatic efforts. Identifying and sharing best practices can improve passage, implementation, efficacy and evaluation of flavoured tobacco policies.

Disaggregating Data to Measure Racial Disparities in COVID-19 Outcomes and Guide Community Response - Hawaii, March 1, 2020-February 28, 2021.

Native Hawaiian and Pacific Islander populations have been disproportionately affected by COVID-19 (1-3). Native Hawaiian, Pacific Islander, and Asian populations vary in language; cultural practices; and social, economic, and environmental experiences,† which can affect health outcomes (4).§ However, data from these populations are often aggregated in analyses. Although data aggregation is often used as an approach to increase sample size and statistical power when analyzing data from smaller population groups, it can limit the understanding of disparities among diverse Native Hawaiian, Pacific Islander, and Asian subpopulations¶ (4-7). To assess disparities in COVID-19 outcomes among Native Hawaiian, Pacific Islander, and Asian populations, a disaggregated, descriptive analysis, informed by recommendations from these communities,** was performed using race data from 21,005 COVID-19 cases and 449 COVID-19-associated deaths reported to the Hawaii State Department of Health (HDOH) during March 1, 2020-February 28, 2021.†† In Hawaii, COVID-19 incidence and mortality rates per 100,000 population were 1,477 and 32, respectively during this period. In analyses with race categories that were not mutually exclusive, including persons of one race alone or in combination with one or more races, Pacific Islander persons, who account for 5% of Hawaii's population, represented 22% of COVID-19 cases and deaths (COVID-19 incidence of 7,070 and mortality rate of 150). Native Hawaiian persons experienced an incidence of 1,181 and a mortality rate of 15. Among subcategories of Asian populations, the highest incidences were experienced by Filipino persons (1,247) and Vietnamese persons (1,200). Disaggregating Native Hawaiian, Pacific Islander, and Asian race data can aid in identifying racial disparities among specific subpopulations and highlights the importance of partnering with communities to develop culturally responsive outreach teams§§ and tailored public health interventions and vaccination campaigns to more effectively address health disparities.

A Cross-Sectional Study Examining Differences in Indication for Cesarean Delivery by Race/Ethnicity.

(1) Background: There are persistent racial/ethnic disparities in cesarean delivery in the United States (U.S.), yet the causes remain unknown. One factor could be provider bias. We examined medical indications for cesarean delivery that involve a greater degree of physician discretion (more subjective) versus medical indications that involve less physician discretion (more objective) to better understand factors contributing to the higher rate among Micronesian, one of the most recent migrant groups in the state, compared to White women in Hawai'i. (2) Methods: A retrospective chart review was conducted to collect data on 620 cesarean deliveries (N = 296 White and N = 324 Micronesian) at the state's largest maternity hospital. Multivariate regression models were used to examine associations between maternal and obstetric characteristics and (1) subjective indication defined as non-reassuring fetal heart tracing (NRFHT) and arrest of labor disorders, and (2) objective indication defined as all other indications (e.g., malpresentation). (3) Results: We found that Micronesian women had significantly higher odds of cesarean delivery due to a subjective indication compared to White women (aOR: 4.17; CI: 2.52-6.88; P < 0.001; N = 619) after adjusting for multiple covariates. (4) Conclusion: These findings suggest unmeasured factors, possibly provider bias, may influence cesarean delivery recommendations for Micronesian women in Hawai'i.

Interaction Between Physical Activity and Polygenic Score on Type 2 Diabetes Mellitus in Older Black and White Participants From the Health and Retirement Study.

This study investigated the association of lifestyle factors and polygenic risk scores (PGS), and their interaction, on type 2 diabetes mellitus (T2D). We examined data from the U.S. Health and Retirement Study, a prospective longitudinal cohort of adults aged 50 years and older, containing nationally representative samples of Black and White Americans with precalculated PGS for T2D (N = 14 001). Predicted prevalence and incidence of T2D were calculated with logistic regression models. We calculated differences in T2D prevalence and incidence by PGS percentiles and for interaction variables using nonparametric bootstrap method. Black participants had approximately twice the prevalence of Whites (26.2% vs 14.2%), with a larger difference between the 90th and 10th PGS percentile from age 50 to 80 years. Significant interaction (pinteraction = .0096) was detected between PGS and physical activity among Whites. Among Whites in the 90th PGS percentile, T2D prevalence for moderate physical activity was 17.0% (95% CI: 14.8, 19.6), 6.8% lower compared to no/some physical activity (23.8%; 95% CI: 20.4, 27.5). T2D prevalence was similar (~10%) for both groups in the 10th PGS percentile. Incident T2D in Whites followed a similar pattern (pinteraction = .0325). No significant interactions with PGS were detected among Black participants. Interaction of different genetic risk profiles with lifestyle factors may inform understanding of varying inventions' efficacy for different groups of people, potentially improving clinical and prevention interventions.

Reinventing health promotion for healthy default beverage laws in the face of COVID-19.

Shortly after a healthy default beverage (HDB) law took effect in Hawai'i, requiring restaurants that serve children's meals to offer healthy beverages with the meals, the COVID-19 pandemic struck. Efforts to contain the virus resulted in changes to restaurants' operations and disrupted HDB implementation efforts. Economic repercussions from containment efforts have exacerbated food insecurity, limited access to healthy foods, and created obstacles to chronic disease management. Promoting healthy default options is critical at a time when engaging in healthy behaviors is difficult, but important, to both prevent and manage chronic disease and decrease COVID-19 risk. This commentary discusses COVID-19's impact on restaurant operations and healthy eating, and the resulting challenges and opportunities for this promising health promotion intervention.

Early and surgical menopause associated with higher Framingham Risk Scores for cardiovascular disease in the Canadian Longitudinal Study on Aging.

OBJECTIVE: In women, the risk of cardiovascular disease (CVD) is higher in the postmenopausal period. The effect that menopausal type, natural versus surgical, or the age at natural menopause has on CVD needs further investigation. To this end, we assessed the association between menopausal type and timing and the 10-year office-based Framingham Risk Score (FRS) in women from the Canadian Longitudinal Study on Aging. METHODS: We included women aged 45 to 85 years from the Canadian Longitudinal Study on Aging Comprehensive cohort of seven Canadian provinces who were menopausal at the time of recruitment and had no prior CVD. Poisson regressions were used to evaluate the association between menopausal characteristics and the FRS. Natural menopause was defined as the cessation of menstrual periods for at least 1 year in women with no history of hysterectomy. Surgical menopause was defined as hysterectomy with or without oophorectomy prior to natural menopause. As main covariates, we examined age, education, province of residency, and hormone therapy. RESULTS: A total of 10,090 women (8,200 natural menopausal and 1,890 surgical menopausal) were eligible for the study. In the multivariable model, surgical menopause was associated with a higher mean FRS compared with natural menopause (CVD risk 12.4% vs 10.8%, P < 0.001). Compared with women with age at natural menopause from 50 to 54 years (CVD risk 10.2%), natural menopause before age 40, 40 to 44, or 45 to 49 had a higher CVD risk (12.2%, 11.4%, and 10.6%, respectively, P < 0.001). CONCLUSIONS: Our study supports an association between menopausal type and timing on CVD risk prediction and highlights the need to be judicious about surgical menopause. Preventative interventions for CVD should be considered in surgical menopausal women and women with an age at natural menopause less than 45 years.
