Objective Despite heterogeneity among Pacific Islanders, most studies aggregate them regardless of origin. Thus, limited information is available about perinatal outcomes among various subgroups of Pacific Islanders in the United States, including immigrants from the Republic of the Marshall Islands. We sought to evaluate perinatal outcomes among Marshallese women. Methods We conducted a cross-sectional study of women with at least one singleton live birth between 1997 and 2013 in two Arkansas counties using birth certificate data from the Arkansas Department of Health. Unadjusted and adjusted prevalence ratios (PR) and 95% confidence intervals (CI) were calculated from modified Poisson regression models. Results Of the 91,662 singleton births in both counties during the study period, 2488 were to Marshallese women. In adjusted analyses, Marshallese women had higher prevalence of 'other medical risk factors' (PR = 1.47; 95% CI 1.30, 1.65) than NH White women. Marshallese women had higher rates of precipitous labor and fetal distress during labor compared to NH White women (PR = 2.65; 95% CI 2.22, 3.17 and 1.89; 95% CI 1.62, 2.21, respectively). Marshallese were also more likely to have tocolysis (PR = 1.43; 95% CI 1.16, 1.76), forceps (PR = 1.68; 95% CI 1.16, 2.43) or vacuum (PR = 1.89; 95% CI 1.60, 2.22) used in delivery and cesarean section (PR = 1.13; 95% CI 1.01, 1.27). Marshallese infants had higher rates of anemia (PR = 3.10; 95% CI 2.01, 4.77), birth injury (PR = 2.13; 95% CI 1.50, 3.03), assisted ventilation < 30 min (PR = 2.11; 95% CI 1.64, 2.71), preterm birth (PR = 1.67; 95% CI 1.50, 1.83), and small-for-gestational age (PR = 1.25; 95% CI 1.12, 1.39) than NH White infants. Conclusions Marshallese women and infants had higher rates of adverse perinatal outcomes compared to their NH White counterparts. Additional studies are needed to determine if perinatal outcomes among the Marshallese differed from other Pacific Islander subgroups., Author(s): Wendy N. Nembhard [sup.1] [sup.2] , Britni L.

Previous research is inconsistent about the effects of prenatal famine exposure on risk of adult hypertension. Follow-up of persons exposed to the 1959-1961 Chinese famine, the largest in human history, provides an opportunity to examine the long-term impact of prenatal famine exposure on adult cardiovascular disease (CVD). We investigated the effects of fetal-infant exposure to the famine on risk of hypertension in adulthood. We included 1,415 participants from the 2009 China Health and Nutrition Survey born September 1, 1956-December 31, 1964. Blood pressure (BP) measurements, self-reported previous diagnosis of hypertension and current anti-hypertension drug use were obtained from the survey. Differences in mean BP and risk of adult hypertension by famine exposure status were determined using linear and logistic regression analyses, after adjusting for confounders. Women with fetal-infant exposure to famine had higher mean systolic blood pressure (4.24 mmHg; 95% confidence interval (CI) 1.50-6.98) than those unexposed. They also had increased odds of a prior diagnosis of hypertension (odds ratio (OR) 2.16; 95% CI 1.16-4.02), and were more likely to be currently taking anti-hypertensive medications (OR 2.81; 95% CI 1.32-5.97) than unexposed women after adjusting for covariates. No statistically significant increases in mean BP or hypertension were seen among men. Exposure to famine during the fetal-infant period or early childhood has deleterious effects on adult health, but the effects may be greater for women. Gender-specific intervention strategies for CVD may be warranted for populations exposed to under-nutrition during critical time periods of fetal development. Keywords Fetal exposure * Gender difference * Hypertension * Blood pressure * Chinese famine, Introduction A growing body of literature suggests that increased risk of chronic diseases in adulthood may actually originate from adverse exposures or under nutrition during the fetal period [1, 2].
