Cardiovascular Risk Factors of Adults Age 20-49 Years in the United States, 1971-2012: A Series of Cross-Sectional Studies.

ABSTRACT:

Background

The health of younger adults in the U.S. has important public health and economic-related implications. However, previous literature is insufficient to fully understand how the health of this group has changed over time. This study examined generational differences in cardiovascular risk factors of younger adults over the past 40 years.

Methods

Data were from 6 nationally representative cross-sectional National Health and Nutrition Examination Surveys (1971-2012; N = 44,670). Participants were adults age 20-49 years who self-reported sociodemographic characteristics and health conditions, and had examination/laboratory measures for hypertension, hyperlipidemia, diabetes, obesity, and chronic kidney disease. Prevalences of sociodemographic characteristics and health status were determined by study period. Logistic regression was used to determine the odds [odds ratio (OR), 95% confidence interval] of health conditions by study period: models adjusted only for age, sex, and race, and fully adjusted models additionally adjusted for socioeconomic characteristics, smoking, BMI, diabetes, and/or hypertension (depending on the outcome) were assessed.

Results

Participants in 2009-2012 were significantly more likely to be obese and have diabetes compared to those in 1971-1975 (OR = 4.98, 3.57-6.97; OR = 3.49, 1.59-7.65, respectively, fully adjusted). Participants in 2009-2012 vs. 1988-1994 were significantly more likely to have had hypertension but uncontrolled hypertension was significantly less likely (OR = 0.67, 0.52-0.86, fully adjusted). There was no difference over time for high cholesterol, but uncontrolled high cholesterol was significantly less likely in 2009-2012 vs. 1988-1994 (OR = 0.80, 0.68-0.94, fully adjusted). The use of hypertensive and cholesterol medications increased while chronic kidney and cardiovascular diseases were relatively stable.

Conclusions

Cardiovascular risk factors of younger U.S. adults have worsened over the past 40 years, but treatment for hypertension and high cholesterol has improved. The sub-optimal and worsening health in younger adults may have a substantial impact on health care utilization and costs, and should be considered when developing health care practices.

Project description:BackgroundPregnant and postpartum women are at increased risk for severe illness from COVID-19. We assessed COVID-19 vaccination coverage, intent, and attitudes among women of reproductive age overall and by pregnancy status in the United States.MethodsData from the National Immunization Survey Adult COVID Module collected during April 22-November 27, 2021, were analyzed to assess COVID-19 vaccination (receipt of ≥1 dose), intent for vaccination, and attitudes towards vaccination among women aged 18-49 years overall and by pregnancy status (trying to get pregnant, currently pregnant, breastfeeding, and not trying to get pregnant or currently pregnant or breastfeeding). Logistic regression and predictive marginals were used to generate unadjusted and adjusted prevalence ratios (PRs and aPRs). Trend analyses were conducted to assess monthly changes in vaccination and intent.ResultsOur analyses included 110,925 women aged 18-49 years. COVID-19 vaccination coverage (≥1 dose) was 63.2% overall (range from 53.3% in HHS Region 4 to 76.5% in HHS Region 1). Vaccination coverage was lowest among pregnant women (45.1%), followed by women who were trying to get pregnant (49.5%), women who were breastfeeding (51.5%), and all other women (64.9%). Non-Hispanic (NH) Black women who were pregnant or breastfeeding had significantly lower vaccination coverage (aPR: 0.74 and 0.66, respectively) than NH White women.DiscussionOur findings are consistent with other studies showing lower vaccination coverage among pregnant individuals, with substantially lower vaccination coverage among NH Black women who are pregnant or breastfeeding. Given the overlapping and disproportionate risks of COVID-19 and maternal mortality among Black women, it is critical that COVID-19 vaccination be strongly recommended for these populations and all women of reproductive age. Healthcare and public health providers may take advantage of every opportunity to encourage vaccination and enlist the assistance of community leaders, particularly in communities with low vaccination coverage.

Project description:Background:Universal salt iodization (USI) is the most feasible and cost-effective, and equitable, approach to prevent iodine deficiency. Severe maternal iodine deficiency during pregnancy is associated with serious adverse gestational and birth outcomes. Objectives:The aim was to assess iodine status and identify independent factors associated with urinary iodine concentration (UIC) among women of reproductive age in Tanzania. Methods:This was a weighted, population-based, cross-sectional study in 2985 women of reproductive age (20-49 y) in Tanzania who participated in the Demographic and Health Surveys in 2015-2016 (DHS 2015-2016) and had measured UIC. Multivariable generalized linear regression was used to identify potential factors that were associated with UIC. Results:The median UICs among women consuming inadequately iodized salt (93.6 ?g/L; 25th and 75th percentiles: 43.1, 197.9 ?g/L) and women in the lowest socioeconomic status (92.3 ?g/L; 45.6, 194.4 ?g/L) were below the WHO-recommended ranges (?150 ?g/L for pregnant women and ?100 ?g/L for nonpregnant women). The results of multivariable models indicated that pregnant women had 1.21 ?g/L lower UIC than nonpregnant women (? = -1.21; 95% CI: -3.42, -0.12), breastfeeding women had 1.02 ?g/L lower UIC than nonbreastfeeding women (? = -1.02; 95% CI: -2.25, -0.27), and women with no education had a 1.88 ?g/L lower UIC compared with those with secondary/highest education (? = -1.88; 95% CI: -4.58, -0.36). Women consuming inadequately iodized salt had 6.55 ?g/L lower UIC than those consuming adequately iodized salt (? = -6.55; 95% CI: -9.24, -4.33). The median UIC varied substantially across geographic zones, ranging from 83.2 ?g/L (45.9, 165.3) in the Western region to 347.8 ?g/L (185.0, 479.8) in the Eastern region. Conclusions:Our findings indicated a great heterogeneity in median UIC across regions of Tanzania among women of reproductive age. Poverty, consuming inadequately iodized salt, and lack of education appeared to be the driving factors for lower UIC in Tanzania.
