National data for ever-married men age 20 to 65 in March 1973 are utilized to estimate least squares and log-linear structural equation models of age at marriage. We demonstrate that most characteristics of family background (including both the family structure and its socioeconomic standing) are irrelevant in their effect on age at marriage. Intercohort trends are not explicable with reference to the changing socioeconomic, ethnic, or nativity compositions of the cohorts. Regional differences in age at marriage have persisted over the years in only slightly diminished form and cannot be explained by reference to the nativity, ethnic, or socioeconomic compositions of the regions. Early job status relates only weakly to age at marriage. Only those activities that are time-consuming or otherwise disruptive of the smooth operation of normal life-cycle processes during the transition from adolescence to adulthood (such as college attendance and service in the military) seriously affect the age at which a man marries.

Background: In 2019, Bard Peripheral Vascular Inc (BV; now Becton, Dickinson and Company; Sparks, Maryland) received Food and Drug Administration (FDA) approval to begin marketing the WavelinQ EndoAVF System through a process known as 510(k) authorization. Such authorization relies on BV proving that the new WavelinQ EndoAVF System was of "substantial equivalence" to the WavelinQ 4F EndoAVF System. We set forth to analyze patient problems and device issues reported for the new device and determine if they were significantly different from the predicate device its 510(k) approval was based on., Methods: FDA database Manufacturer and User Facility Device Experience was queried for all adverse report events for the WavelinQ EndoAVF System and WavelinQ 4F EndoAVF System. Data were collected on patient issues and device issues. Fisher's exact test was used., Results: There were a total of 125 reports for the WavelinQ 4F EndoAVF System and 78 for the WavelinQ EndoAVF System. There was a significant increase in patient problem "hypertension" (0% vs. 5.1%; P = 0.02) for the WavelinQ EndoAVF System but a statistically significant decrease in device issue "failure to align" for the WavelinQ EndoAVF System (24.8% vs. 10.3%; P ≤ 0.01)., Conclusions: There were changes in device and patient outcomes between the WavelinQ EndoAVF System and WavelinQ 4F EndoAVF System. While we noted a decrease in device problem "failure to align", there was an overall increase in patients' "hypertension" rates. This highlights the importance of the FDA Manufacturer and User Facility Device Experience reporting in ensuring that device safety is maintained when devices are approved for marketing through the 510(k) process., (Published by Elsevier Inc.)

Background: Millennium Development Goal 5 calls for a 75% reduction in the maternal mortality ratio (MMR) between 1990 and 2015. We estimated levels and trends in maternal mortality for 183 countries to assess progress made. Based on MMR estimates for 2015, we constructed projections to show the requirements for the Sustainable Development Goal (SDG) of less than 70 maternal deaths per 100,000 livebirths globally by 2030., Methods: We updated the UN Maternal Mortality Estimation Inter-Agency Group (MMEIG) database with more than 200 additional records (vital statistics from civil registration systems, surveys, studies, or reports). We generated estimates of maternal mortality and related indicators with 80% uncertainty intervals (UIs) using a Bayesian model. The model combines the rate of change implied by a multilevel regression model with a time-series model to capture data-driven changes in country-specific MMRs, and includes a data model to adjust for systematic and random errors associated with different data sources., Results: We had data for 171 of 183 countries. The global MMR fell from 385 deaths per 100,000 livebirths (80% UI 359-427) in 1990, to 216 (207-249) in 2015, corresponding to a relative decline of 43·9% (34·0-48·7), with 303,000 (291,000-349,000) maternal deaths worldwide in 2015. Regional progress in reducing the MMR since 1990 ranged from an annual rate of reduction of 1·8% (0·0-3·1) in the Caribbean to 5·0% (4·0-6·0) in eastern Asia. Regional MMRs for 2015 ranged from 12 deaths per 100,000 livebirths (11-14) for high-income regions to 546 (511-652) for sub-Saharan Africa. Accelerated progress will be needed to achieve the SDG goal; countries will need to reduce their MMRs at an annual rate of reduction of at least 7·5%., Interpretation: Despite global progress in reducing maternal mortality, immediate action is needed to meet the ambitious SDG 2030 target, and ultimately eliminate preventable maternal mortality. Although the rates of reduction that are needed to achieve country-specific SDG targets are ambitious for most high mortality countries, countries that made a concerted effort to reduce maternal mortality between 2000 and 2010 provide inspiration and guidance on how to accomplish the acceleration necessary to substantially reduce preventable maternal deaths., Funding: National University of Singapore, National Institute of Child Health and Human Development, USAID, and the UNDP/UNFPA/UNICEF/WHO/World Bank Special Programme of Research, Development and Research Training in Human Reproduction., (Copyright © 2016 World Health Organization.

Objective: The purpose of this study is to examine depression care among chronically ill Medicare Advantage beneficiaries., Methods: This study includes 5898 Medicare Advantage members with a depression diagnosis enrolled between 2008 and 2010 in a care management program. Two depression care indicators were created: (a) any depression care (≥ 1 antidepressant prescription or ≥ 1 specialty mental health visit) and (b) among those receiving any depression care, those receiving an antidepressant prescription for ≥ 90 days or ≥ 2 specialty visits. Multivariable analysis using logistic regression was used to examine correlates of depression care., Results: Among those <65 years old, 72% received any depression care with 75% receiving ≥ 90 days of an antidepressant and/or ≥ 2 specialty visits. Among ≥ 65 years old, 65% received any depression care with 67% receiving ≥ 90 days of an antidepressant and/or ≥ 2 specialty visits. For both age groups, female gender, medical comorbidities and dual eligibility were positively associated with an antidepressant prescription. In the older group, female gender was positively associated with at least a 90-day supply of an antidepressant prescription, while substance use disorders were negatively associated with receiving a minimum of 90 days of an antidepressant. Regional differences and certain psychiatric comorbidities were also associated with receiving depression care., Conclusion: Two thirds of the depressed patients in this Medicare Advantage population received depression care. Further studies are needed to examine the effects of quality improvement efforts in the context of care management programs for chronically ill older adults., (Copyright © 2013 Elsevier Inc.

Contact dermatitis is a serious public health and dermatologic concern. The prevalence of contact dermatitis in the United States was estimated to be 13.6 per 1000 population according to the National Health and Nutritional Examination Survey using physical examinations by dermatologists of a selected sample of Americans. The American Medical Care Survey estimated that for all American physicians dermatitis is the second most common dermatologic diagnosis proffered. It is essential that government, industry, and dermatologists work together to enhance regulatory methods to control and prevent contact allergy epidemics. Increased knowledge and awareness of occupational skin diseases by dermatologists and other health care professionals will assist in achieving national public health goals. This article reviews governmental regulations-some helpful for patients and workers and some not helpful for dermatologists in their quest to assist patients with contact dermatitis.

Objectives: To examine the association between depression and healthcare costs in medically ill fee-for-service (FFS) Medicare recipients., Study Design: Observational analysis of Medicare claims data., Setting: Medicare Health Support (MHS) program at Green Ribbon Health., Participants: Fourteen thousand nine hundred two participants with diabetes mellitus, congestive heart failure (CHF), or both., Measurements: This study examined participant data for a 12-month period before MHS enrollment (collected between November 2004 and August 2006). Twelve-month healthcare costs (based on Medicare claims) in 2,108 participants with International Classification of Diseases, Ninth Revision, claims diagnoses of depression, 1,081 participants with possible depression (positive depression screen on the two-item Patient Health Questionnaire or self reported antidepressant use), and 11,713 participants without depression were compared. Gamma regression models were used to adjust for demographic and clinical differences and nonnormal distribution of cost data., Results: Participants with depression had significantly higher total healthcare costs than those without ($20,046 vs $11,956; P<.01). Higher costs were observed in participants with depression in every cost category except specialty mental health care, which accounted for less than 1% of total healthcare costs. Participants with depression had higher costs in each quartile of increasing medical severity (measured using the Charlson Comorbidity Index). These differences remained statistically significant after adjusting for demographic and other clinical differences., Conclusion: Depression is associated with significantly higher healthcare costs in FFS Medicare recipients with diabetes mellitus and CHF. Only a small proportion of the increased costs are spent on mental health specialty care.

Objectives: Although several national health surveys have implemented data collection efforts to identify and characterize disability among children, the large number of items these surveys have required to measure childhood disability prohibit their use in general population surveys. Using a conceptually based approach, we examine whether concise sets of survey items--feasible for use in general population surveys--can be used to measure functional limitations in activities among children., Methods: We analyze three nationally representative population surveys that contain detailed questions on childhood activity limitations. We first examine the full set of survey items and then eliminate survey items, one by one, exploring different combinations and examining the results of each successive elimination., Results: Across the three surveys, we consistently demonstrate that it is possible to reduce the number of survey items needed to measure childhood activity limitations and still produce comparable estimates. Concise sets of measures may contain as few as six items, making it possible to include in general population surveys. However, our concise sets of measures do not produce comparable estimates across surveys, which reflects differences in the types of questions and differences in the wording of questions found in the original survey instruments., Conclusions: On the basis of our findings, we reemphasize the importance of the wording of survey questions, the importance of validating survey questions, and finally, we recommend a concise set of items that can be used to measure childhood activity limitations in general population surveys.

Objectives: To compare measures of well-being in children with and without different types and severity of limitations., Design: Nationally representative data for American children aged 5 to 17 years were drawn from the 1994 and 1995 National Health Interview Surveys on Disability (NHIS-D) (N = 41,300) and the Year 2000 Health Supplement to the 1994 NHIS-D (N = 9530). Family resources, safety, health status, and health access were measures of environment. The presence and severity of limitations were measured in the domains of mobility, self-care, communication, and learning., Results: Children with functional limitations were more likely to live in families with limited resources and have greater exposure to secondhand smoke, less access to health care, and lower health status. Children with a limitation were not less likely to have a regular source of medical care, but they more often were delayed or prevented from getting necessary health care due to cost or insurance., Conclusions: Standard measures of child well-being were appropriate for children with functional limitations and showed their unfavorable situations. Children with functional limitations more often have unfavorable family resources, less healthy home environments, poorer health status, and less health service access than other children, making them more susceptible to developmental difficulties beyond those difficulties associated with the challenges of their specific functional limitations.

Objectives: This study characterized changes in sexual and reproductive behaviors from 1985 through 1995 among American females aged 15 to 19 years and related these changes to family factors., Methods: Nationally representative sample survey data from the 1995 National Survey of Family Growth were analyzed with Weibull hazards models of age at first intercourse and first pregnancy and with logistic regression models of contraceptive use at first intercourse and pregnancy outcome., Results: Improvements in the family socioeconomic situations of young women have lessened the risk of teen motherhood, while changes in family structure have increased the risk. Young women whose parents have more than a high school education, who live with both parents, and who attend church delay the timing of first sexual intercourse and are more likely to use a contraceptive., Conclusions: The trend of increases in teenage motherhood has ended owing to a halt in increases in the proportion of sexually active young women and substantial improvement in contraception, with the greatest improvements among those from advantageous family situations.

This study used data that were representative of the normative population of all infants born in 1988 and were followed during the first 3 years of life. Large developmental delays and limitations in function were common among children weighing less than 1500 g at birth. Among very low-birth weight infants, minority status and living in a household headed by a single mother further worsen the disadvantages associated with a very low birth weight. Nor could the disadvantages associated with very low birth weight be accounted for by controls for other risk factors or buffering statuses and behaviors. Among all children (including those of very low birth weight) poverty, reliance on Medicaid and other government sources for health insurance, a history of risky behaviors, and inadequate prenatal care are the major risk factors for developmental delays, limitations in function, and impairment at birth. State program benefit levels have no obvious effects on child outcomes, taking into account participation in individual programs. An important finding in light of TANF is that maternal work, the use of child care, and the form and cost of child care did not influence developmental delay, limitation in function, or impairment, the outcomes that we were able to measure during the first 3 years of life. TANF eligibility requirements, however, may increase difficulty in obtaining prenatal and other medical services for mothers and children in need--factors shown here to be related strongly to increased risk of low birth weight and developmental delays, limitations, and impairments. Race and ethnicity, poverty status, and family structure are fundamental factors in early child development and function. Minority status, poverty, and single-parent households greatly increase the likelihood that a mother will engage in risky behaviors (smoking, alcohol use, illegal drug use) during pregnancy and receive inadequate prenatal care. Risky behaviors and inadequate prenatal care are the major risk factors for a baby of very low birth weight. When perinatologists first encounter a new patient who is of very low birth weight they often see an infant who is minority, in poverty, and in a single-parent household. Although such children did more poorly in development and function by age 3, the major effects of these variables were through the selectivity of such children into very low birth weight; the direct impact of these factors on development is somewhat muted. This research suggests there are a number of policies that can reduce development delays and functional limitations among children in the United States. Programs that are targeted to a mother and child (such as WIC, AFDC, health insurance coverage, and possibly the more recent TANF programs) significantly reduced the risk an infant will be of very low birth weight. Access and use of adequate prenatal care are essential. Programs designed to combat maternal behaviors that place the fetus at risk (smoking, alcohol, and illegal drug use) can be very successful in reducing the likelihood an infant will be of very low birth weight. An additional payoff from such programs comes after the birth, because even taking into account birth weight, these variables negatively impact on early childhood development and function. Single-parent family structure, race and ethnic minority status, and poverty status also are known to impact on kindergarten readiness, so that we expect a delayed impact of these variables on the child. The strength of this article is the use of normative population data to assess the role of birth weight in child outcome. We examined prenatal risk factors for a baby of very low birth weight, traced the manner by which these selective risks are reflected in the composition of very low-birth weight babies, demonstrated how a very low birth weight was fundamental to delays in development, and identified risk factors and potential buffers in this process.

North America suffers some of the most severe tornado disasters of any location on the planet. Significant injury and economic impact may result from these storms, particularly in rural areas. Tornadic storms present unique problems for prehospital and Emergency Department personnel. Soft tissue injuries seen after tornadoes are contaminated with polymicrobial flora and may require delayed primary closure. Fractures are a frequent cause of hospital admission and head injury is a frequent cause of death. Advanced warning and proper sheltering actions by a population are the most significant factors in reducing morbidity and mortality. This article reviews the pertinent literature on the medical impact of tornadoes and details the mechanisms of injury, nature of injuries, pre-hospital and ED planning points associated with tornadic storms.

Objectives: To provide a brief overview of the oncologic emergencies most commonly occurring in lymphoma patients., Data Sources: Published articles, research studies, and reference books., Conclusions: As a result of their malignancy and the treatments they receive, lymphoma patients are at an increased risk for the development of the following oncologic emergencies: superior vena cava syndrome, cardiac tamponade, sepsis, acute tumor lysis syndrome, and increased intracranial pressure. If not recognized and treated quickly, these complications can be deadly. With appropriate medical and nursing management, these emergencies either can be prevented or their complications minimized., Implications for Nursing Practice: An awareness of which patients are at risk for these complications and the pathophysiology of each emergency will assist nurses in the implementation of treatment measures.

Objectives: This paper (a) creates and validates measures for population survey data to assess functional limitation in mobility, self-care, communication, and learning ability for school-age American children; (b) calculates rates of functional limitation using these measures, and provides population estimates of the number of children with limitations; and (c) examines these limitations as a function of socioeconomic factors., Method: The study is based on data for children aged 5-17 collected in the 1994 National Health Interview Survey on Disability. Ordinal values are assigned to survey items in the four functional areas and analyzed to produce scales of high reliability. These measures are used to identify within a 95% confidence interval the number of children with these limitations. Ordered logistic regression models measure the effects of functional limitations on disability and societal limitation. Socioeconomic differences are measured with an ordered logistic regression model that predicts severity and comorbidity., Results: Limitations in learning ability (10.6%) and communication (5.5%) are the most common, with mobility (1.3%) and self-care (0.9%) occurring less often. Six percent of children have one serious functional limitation and 2.0% have two or more serious functional limitations. This corresponds to 4.0 million school-age American children with serious functional limitations. Functional limitation is strongly linked to socioeconomic disadvantage and to residence in single-mother households., Conclusions: Future population research should use multiple-item scales for four distinct areas of functional limitation, and a summary that takes into account both severity and comorbidity. The improved estimates of the number of school-age children with functional limitation in this paper may help contribute to a more informed scientific and policy discussion of functional limitation and disability among American school-age children. Future research on the disability process among children must consider the role of socioeconomic disadvantage and family structure.

We used 1990 census data to examine differences in the current living arrangements of minority elderly. We found that differences among the minority populations in age, sex, and marital status account for only a small part of the observed differences in living arrangements. However, while minority groups as a whole differ substantially from the White population, national ethnic patterns within groups appear to be relatively small. Hispanic ethnic groups vary little once differences in marriage patterns are taken into account, although differences are greater within the Asian population.

Methods of conducting comprehensive geriatric evaluation and management (GEM) are proliferating in a variety of clinical settings. However, rigorous evaluations of efficacy for this new approach to care of older patients have demonstrated a favorable impact on patient outcome in only a few studies. All of these have been controlled single site studies, and replication is needed. If replication studies show similar results, further studies should be undertaken to define the minimum necessary intervention to achieve the desired outcome. Controlled trials are needed to determine if consultative geriatric evaluation and/or primary patient management is effective. Further innovative work is needed in model development for geriatric assessment and management in outpatient settings. Finally, studies of geriatric evaluation and management in other environments, such as home care or the nursing home, are recommended.

This paper examines the effects of kin access on prenatal health practices, birth outcome, and postnatal health practice for infants born to black and white mothers ages 21 to 28 in the U.S. during 1984-86. The data used for this research were compiled from three sources: (1) The National Longitudinal Survey of Youth; (2) The Children of the National Longitudinal Survey of Youth; (3) special kin access data files, which were created specifically for this study. Logistic regression procedures are used to assess the effects of kin proximity, maternal grandmother proximity, and presence of the child's father on health practices (N = 1,030) and birth outcome (N = 1,385), controlling for the mother's educational attainment, work experience, poverty, presence of the child's father, and birth order of the child. We find no evidence supporting the notion that kin access positively affects the prenatal and postnatal health practices of young mothers. The results suggest that young mothers who reside with their mothers or other adult kin, and those who are in close proximity to them, are no more likely to seek prenatal care during the first trimester, or to avoid smoking or drinking during pregnancy. Mothers who live with a sexual partner or husband are, however, somewhat more likely to seek prenatal care and to avoid alcohol use during pregnancy. Closer kin access is associated with a lower probability of breastfeeding. These results suggest that it will not be adequate to rely on kin networks or kin assistance to improve the prospect of healthy birth outcomes.
