Changes in the use of effective and long-acting reversible contraception in Vietnam

Objectives

To calculate the prevalence and identify correlates of unmet need for contraception and to assess whether prevalence of use of effective contraception and long-acting reversible contraception (LARC) has changed over time among married or cohabiting, reproductive-age women in Vietnam.

Counseling and provision of long-acting reversible contraception in the US: National survey of nurse practitioners

Objective

Nurse practitioners (NPs) provide frontline care in women's health, including contraception, an essential preventive service. Their importance for contraceptive care will grow, with healthcare reforms focused on affordable primary care. This study assessed practice and training needs to prepare NPs to offer high-efficacy contraceptives — intrauterine devices (IUDs) and implants.

Method

A US nationally representative sample of nurse practitioners in primary care and women's health was surveyed in 2009 (response rate 69%, n = 586) to assess clinician knowledge and practices, guided by the CDC US Medical Eligibility Criteria for Contraceptive Use.

Results

Two-thirds of women's health NPs (66%) were trained in IUD insertions, compared to 12% of primary care NPs. Contraceptive counseling that routinely included IUDs was low overall (43%). Nurse practitioners used overly restrictive patient eligibility criteria, inconsistent with CDC guidelines. Insertion training (aOR = 2.4, 95%CI: 1.10 5.33) and knowledge of patient eligibility (aOR = 2.9, 95%CI: 1.91 4.32) were associated with IUD provision. Contraceptive implant provision was low: 42% of NPs in women's health and 10% in primary care. Half of NPs desired training in these methods.

Conclusion

Nurse practitioners have an increasingly important position in addressing high unintended pregnancy in the US, but require specific training in long-acting reversible contraceptives.     

Burden of unintended pregnancy in the United States: potential savings with increased use of long-acting reversible contraception

BackgroundThis study evaluated the total costs of unintended pregnancy (UP) in the United States (US) from a third-party health care payer perspective and explored the potential role for long-acting reversible contraception (LARC) in reducing UP and resulting health care expenditure.Study DesignAn economic model was constructed to estimate direct costs of UP as well as the proportion of UP costs that could be attributed to imperfect contraceptive adherence. The model considered all women requiring reversible contraception in the US: the pattern of contraceptive use and the rates of UP were derived from published sources. The costs of UP in the United States and the proportion of total cost that might be avoided by improved adherence through increased use of LARC were estimated.ResultsAnnual medical costs of UP in the United States were estimated to be $4.6 billion, and 53% of these were attributed to imperfect contraceptive adherence. If 10% of women aged 20–29 years switched from oral contraception to LARC, total costs would be reduced by $288 million per year.ConclusionsImperfect contraceptive adherence leads to substantial UP and high, avoidable costs. Improved uptake of LARC may generate health care cost savings by reducing contraceptive non-adherence.     

Discontinuation and resumption of contraceptive use: results from the 2002 National Survey of Family Growth

BACKGROUND: Discontinuation of contraceptive use that is not immediately followed by resumption of use of another method while a woman is at risk is a common cause of unintended pregnancy. STUDY DESIGN: We provide new estimates of discontinuation for the pill, injectable, male condom, withdrawal and fertility-awareness-based methods, and identify socioeconomic characteristics associated with discontinuation for the pill, male condom and withdrawal. We provide new estimates of resumption of use by prior method used and identify socioeconomic characteristics associated with resumption of use. Estimates are obtained using the 2002 National Survey of Family Growth, supplemented by the 2001 Abortion Patient Survey to correct for underreporting of abortion. RESULTS: The fraction of method use segments discontinued for method-related reasons within 1 year was highest for the male condom (57%), withdrawal (54%) and fertility-awareness-based methods (53%), and lowest for the pill (33%), with the injectable in-between (44%). However, contraception was abandoned altogether in only 25% of cases. The probability of resuming use of a contraceptive was 72% in the initial month of exposure to the risk of an unintended pregnancy; this rose to 76% by the third month. CONCLUSION: The risk of discontinuation of use of reversible methods of contraception for method-related reasons, including a change of method, is very high, but fortunately the risk of abandoning use of contraception altogether is far lower, and most spells of exposure to risk of an unintended pregnancy following discontinuation are protected from the start by a switch to another method.     

Contraceptive use by disability status: new national estimates from the National Survey of Family Growth

Objective

The objective was to determine population-based estimates of use of contraception among women 15–44?years of age in the United States by disability status.

Contraceptive failure, method-related discontinuation and resumption of use: results from the 1995 National Survey of Family Growth

This study computed life table probabilities of contraceptive failure, discontinuation of use, and return to contraceptive use in the US. Data were obtained from the 1995 National Survey of Family Growth (NSFG) among a nationally representative sample of 6867 contraceptive use intervals contributed by women 15-45 years old who began use or resumed use after discontinuation during 1991-95. Analysis was based on Kaplan-Meier product-limit single decrement life table probability methods. Findings indicate that the risk of failure during typical use of reversible methods was 9% within 1 year of starting. Women with continuous lifetime use will experience 1.8 contraceptive failures. Failure rates were 7% for the pill, 9% for the male condom, 8% for the diaphragm, 20% for periodic abstinence, and 15% for spermicides. Failure rates reflect imperfect use. 31% of women discontinued use within 6 months of starting use. 44% discontinued within 12 months. Women using reversible methods continuously will discontinue use nearly 10 times during the reproductive period. Most women resumed use shortly after discontinuation. Low income women had higher risk of unintended pregnancy for all methods and the pill and lower risk of resumption after discontinuation. Hispanics had a higher risk of contraceptive failure for all methods and the condom. Black women had a higher risk of discontinuation of oral pills and condoms.     

Childlessness in the United States: estimates from the National Survey of Family Growth

Using a representative sample of about 17,000 ever married women 15 to 44 years of age, this article presents national estimates of the prevalence and correlates of voluntary, involuntary, and temporary childlessness in the United States. These three groups of childless couples are compared with the parents of small planned families and other parents on a number of social, economic, marital, and family characteristics. When viewed cross sectionally, voluntarily childless couples constitute between 1.3% and 1.8% of currently married couples, depending on the definitions used. They are a distinctive but rare population. Their future prevalence depends primarily on the decisions of the large group of temporarily childless couples.     

Contraceptive failure rates: new estimates from the 1995 National Survey of Family Growth

CONTEXT: Unintended pregnancy remains a major public health concern in the United States. Information on pregnancy rates among contraceptive users is needed to guide medical professionals' recommendations and individuals' choices of contraceptive methods. METHODS: Data were taken from the 1995 National Survey of Family Growth (NSFG) and the 1994-1995 Abortion Patient Survey (APS). Hazards models were used to estimate method-specific contraceptive failure rates during the first six months and during the first year of contraceptive use for all U.S. women. In addition, rates were corrected to take into account the underreporting of induced abortion in the NSFG. Corrected 12-month failure rates were also estimated for subgroups of women by age, union status, poverty level, race or ethnicity, and religion. RESULTS: When contraceptive methods are ranked by effectiveness over the first 12 months of use (corrected for abortion underreporting), the implant and injectables have the lowest failure rates (2-3%), followed by the pill (8%), the diaphragm and the cervical cap (12%), the male condom (14%), periodic abstinence (21%), withdrawal (24%) and spermicides (26%). In general, failure rates are highest among cohabiting and other unmarried women, among those with an annual family income below 200% of the federal poverty level, among black and Hispanic women, among adolescents and among women in their 20s. For example, adolescent women who are not married but are cohabiting experience a failure rate of about 31% in the first year of contraceptive use, while the 12-month failure rate among married women aged 30 and older is only 7%. Black women have a contraceptive failure rate of about 19%, and this rate does not vary by family income; in contrast, overall 12-month rates are lower among Hispanic women (15%) and white women (10%), but vary by income, with poorer women having substantially greater failure rates than more affluent women. CONCLUSIONS: Levels of contraceptive failure vary widely by method, as well as by personal and background characteristics. Income's strong influence on contraceptive failure suggests that access barriers and the general disadvantage associated with poverty seriously impede effective contraceptive practice in the United States.     

Contraceptive failure in the United States: estimates from the 1982 National Survey of Family Growth

A multivariate life-table analysis of national survey data from 1982 indicates that among currently married women, the pill and IUD have the lowest use-failure rates. During the first year of use, about three percent of pill users and six percent of IUD users experience an unintended pregnancy. Failure rates for the remaining methods range from 14 percent for the condom to 22 percent for spermicides; between these lie rhythm and natural family planning (16 percent), the diaphragm (17 percent) and other methods, mainly withdrawal, douche and abstinence. Married women using no contraceptive method experience an unintended pregnancy rate of 40 percent during the first year of unprotected intercourse. A woman's age, pregnancy intention (either to delay or to prevent births), parity and income all have significant effects on the risk of unintended pregnancy. The risk generally declines with age, except for women attempting to prevent an unwanted pregnancy, among whom women under 20 have lower failure rates than do those 20-29 years of age. As expected, women attempting to prevent an unwanted pregnancy have lower failure rates than do those seeking to delay a wanted pregnancy, with the difference being greatest for women under 20 years of age and smallest for 20-29-year-olds. Use-failure rates among low-income women are higher than those among women with larger family incomes, while low-parity women have lower failure rates than do women of higher parity. On average, standardized use-failure rates for single women are lower than those for married women, probably because of a lower average level of intercourse among single women. In addition, these rates are understated because of the substantial underreporting of abortion among single women; if abortion reporting were complete, failure rates would be about 1.4 times as high as they appear here, and thus would be close to those of married women. Differences in the risk of unintended pregnancy among single women show a number of similarities with those seen among married women: Use of the pill and IUD is associated with the lowest failure rates, reliance on the condom is associated with intermediate failure rates, and use of spermicides is linked with the highest failure rates. However, while rhythm and the diaphragm exhibit use-failure rates that are among the highest found for single women, failure rates for these methods are at intermediate levels among married women.(ABSTRACT TRUNCATED AT 400 WORDS)     

Underreporting of induced and spontaneous abortion in the United States: an analysis of the 2002 National Survey of Family Growth

Underreporting of induced abortions in surveys is widespread, both in countries where the procedure is illegal or highly restricted and in those where it is legal. In this study, we find that fewer than one half of induced abortions performed in the United States in 1997-2001 (47 percent) were reported by women during face-to-face interviews in the 2002 National Survey of Family Growth (NSFG). Hispanic and black women and those with low income were among the least likely to report their experience of abortion. Women were also less likely to report abortions that occurred when they were in their 20s. Second-trimester abortions were more likely to be reported than first-trimester terminations. The levels of recent spontaneous abortion reported in the 2002 NSFG were consistent with the accumulated body of clinical research, although substantially more lifetime pregnancy losses were reported on self-administered surveys than in face-to-face interviews. Subsequent research should explore strategies to improve information collected on abortion, and, in the interim, research involving pregnancy outcomes should be adjusted for unreported induced abortions.     

Association of Socioeconomic Status, Problem Behaviors, and Disordered Eating in Mexican Adolescents: Results of the Mexican National Health and Nutrition Survey 2006

Purpose

To explore the association of socioeconomic status (SES) with disordered eating behaviors (DEB) in Mexican adolescents, and the coexistence of DEB and other problem behaviors.

Methods

Information about adolescents (10–19 years) was retrieved from the Mexican National Health and Nutrition Survey 2006 database. Associations were evaluated through ordinal regression.

Results

Higher SES was associated with DEB (odds ratio [OR]: 2.05, 95% confidence interval [CI]: 1.52–2.75). Use of tobacco (OR: 2.10, 95% CI: 1.58–2.81), alcohol (OR: 2.03, 95% CI: 1.51–2.56), and suicide intent (OR: 5.13, 95% CI: 3.46–7.60) were associated with DEB.

Conclusion

DEB were more frequent among adolescents from higher SES households. The lack of association between SES and DEB reported by other studies might be because of the lack of variability in samples. The association of DEB and other problem behaviors highlights the importance of an integral approach to teenagers' mental health.     

Contraceptive sterilization use among married men in the United States: results from the male sample of the National Survey of Family Growth

Background

Surgical sterilization has many advantages. Previous information on prevalence and correlates was based on surveys of women.

Study Design

We estimated the prevalence of vasectomy and tubal ligation of partners for male participants in the 2002 National Survey of Family Growth, a nationally representative survey of US residents aged 15-44 years. We identified factors associated with sterilizations using bivariate and multivariate techniques.

Results

The findings revealed that 13.3% of married men reported having had a vasectomy and 13.8% reported tubal sterilization in their partners. Vasectomy increased with older age and greater number of biological children, non-Hispanic white ethnicity, having ever gone to a family planning clinic. Tubal sterilization use was more likely among men who had not attended college, those of older age and those with live births.

Discussion

One in eight married men reported having vasectomies. Men who rely on vasectomies have a somewhat different profile than those whose partners have had tubal sterilizations.     

Socioeconomic inequality trends in childhood vaccination coverage in India: Findings from multiple rounds of National Family Health Survey

ObjectivesThis article examines the inequality patterns in childhood vaccination coverage at various socio-economic levels using all four rounds of nationally representative National Family Health Surveys (NFHS) in India.MethodsThe analytic sample restricted to the most recent singleton surviving children aged 12–23 months in each survey, was 11,599 in NFHS‐1 (1992–93); 10,209 in NFHS‐2 (1998–99); 9582 in NFHS‐3 (2005–06) and 49,284 in NFHS‐4 (2015–16). Complete childhood vaccination is defined as a child aged 12–23 months who received one dose of BCG (Bacille Calmette Guerin), one dose of measles, and three doses each of DPT (Diphtheria, Pertussis, Tetanus), and polio vaccine (excluding the polio vaccine given at birth) at any time before the survey—according to the vaccination card or the mother’s recall. To understand inequalities in childhood vaccination, four measures were computed for each survey rounds’ data—absolute measures of inequality, the slope index of inequality (SII), and two relative measures: the ratio between the extreme groups and the concentration index (CIX) to see the degree of disparity.ResultsThe pro-rich and pro-education inequality in childhood vaccination coverage increased between 1998–99 and 2005–06 and declined considerably thereafter. This study found that inequality in childhood vaccination coverage has been minimized at a macro level such as rural-urban, male-female, religion, ethnicity, and in select geographies, but not universally at the micro-level. Findings indicate that pro-rich and pro-education inequalities were large among specific sub-groups of population: children in rural areas, children living in the northern region of the country and among scheduled tribes—as absolute and relative inequalities remained significantly high.ConclusionThese findings recommend robust program monitoring and policy-level support at the micro level to optimize the use of existing resources across all segments of the population in the country.     

Cesarean section deliveries in the occupied Palestinian territory (oPt): An analysis of the 2006 Palestinian Family Health Survey

ObjectiveAgainst the backdrop of a rise in cesarean section deliveries from 6.0% in 1996 to 14.8% in 2006, the objective of this study was to investigate socio-demographic, clinical and service-related factors associated with cesarean sections in the occupied Palestinian territory.MethodsData from the Palestinian Family Health Survey 2006 were used to examine last births in the 5 years preceding the survey to women aged 15–49 years. Bivariate and multivariate associations between type of delivery (dependent variable) and selected factors were analyzed using logistic regression. Selected maternal outcomes were also investigated with type of delivery as the independent variable.ResultsCesarean section deliveries were significantly associated with maternal age (35+ years), primiparity, low birth weight and residence area in the West Bank and Gaza. There was no significant difference in the prevalence of cesarean deliveries by sector in the West Bank, but in Gaza, they were significantly more common in the governmental sector.ConclusionsThere is a need for detailed audits of cesarean section deliveries, nationally and at the facility level, in order to avoid unnecessary interventions in the context of high fertility, rising poverty and fragmented health services. Variations by governorate should be studied further for focused interventions.
