Trends and predictors of changes in modern contraceptive use among women aged 15-49 years in Tanzania from 2004-2016: Evidence from Tanzania Demographic and Health Surveys.

ABSTRACT: INTRODUCTION:Modern contraceptive use provides opportunities for women and couples to achieve optimal child spacing, achieve desired family size and reduce unsafe abortions. Despite these facts, modern contraceptive prevalence rate (mCPR) in Tanzania remains as low as 32%. This study aimed to determine trends and factors associated with changes in modern contraceptive use among women of reproductive age in Tanzania from 2004-2016. METHODOLOGY:This was a cross-sectional study utilizing data from Tanzania Demographic and Health Surveys of 2004-2005, 2010 and 2015-2016. Data analysis was performed using Stata version 14. Analysis considered the complex survey design through application of weights, clustering and strata. Multivariable Poisson decomposition analysis was used to assess factors associated with changes in modern contraceptive use. Results were presented in the form of decomposition coefficients and percentages. RESULTS:Modern contraceptive use increased from 23.0% in 2004 to 34.3% in 2016. Differences in women's characteristics contributed 12.5% of the increase in mCPR. These characteristics include partner's education levels, recent sexual activity and being visited by a family planning worker. The difference in coefficients contributed 87.5% increase in mCPR. The most increase in modern contraceptive use was attributed to rural population (44.1%) and women who experienced a termination of pregnancy (7.1%). CONCLUSION:Modern contraceptive use has steadily increased in Tanzania. Health policies and interventions need to target sexually active women, rural residents as well as less educated women and men to maintain and further accelerate the trends in mCPR. Interventions focusing on women who experienced a termination of pregnancy may also serve as an entry point to promote use of modern contraceptive methods.

Project description:BackgroundPostpartum contraceptive use is vital to improve maternal and child survival. It helps to have optimal child spacing, prevent unplanned pregnancies and associated adverse birth outcomes. However, postpartum contraceptive use in Tanzania remains low. Short median interval for resumption to sex after birth among African women has been associated with adverse maternal and child health wellbeing. This study aimed to assess optimal time to contraceptive use and predictors of time to contraceptive use after birth among women of reproductive age in Tanzania.MethodsA cross section study using the TDHS 2015-16 data was used. A total of 3775 postpartum women were analyzed. Information on pregnancy, births and contraceptive use were recorded over the previous 5 years with the focus on most recent birth from the contraceptive calendar. Data analysis was performed using Stata 14.0. Analysis accounted for complex survey design. Time to modern contraceptive use after birth was computed using Kaplan Meier estimate. Adjusted time ratios with 95% CI were estimated using Weibull accelerated failure time models.ResultsA total weighted sample of 3775 women was analyzed. The median time to contraceptive use after birth was 7(IQR: 4-13) months, while for resumption to sex afterbirth was 2(IQR: 1-5) months. Factors such as never been married (TR: 1.63; 95%CI: 1.26-2.11) and breastfeeding (TR: 5.50; 95%CI: 4.12-7.35) were associated with longer time to postpartum contraceptive use. Belonging to richest wealth quintile (TR: 0.73; 95%CI: 0.54-0.99) and adopting long acting methods (TR: 0.70; 95%CI: 0.60-0.82) increased women's likelihood of having shorter time to postpartum contraceptive use.ConclusionThere was a time lag of five months from resumption of sex and initiation of postpartum contraception use. The interceptive measures to facilitate timely availing methods of women's choice and promotion of utilization of maternal health care services may reduce delays in postpartum contraceptive use.

Project description:ObjectiveTo estimate educational and wealth inequalities in demand satisfied with modern methods of family planning (mDFPS).DesignA secondary data analyses of Demographic and Health Surveys.SettingSix South Asian countries, Afghanistan (2015), Bangladesh (2014), India (2015-2016), Maldives (2016-2017), Nepal (2016) and Pakistan (2017-2018).ParticipantsWomen aged 15-49 years. Primary and secondary outcome measures mDFPS was defined as married women aged 15-49 years or their partners, who desired no child, no additional children or to postpone the next pregnancy and who are currently using any modern contraceptive method. We estimated weighted and age-standardised estimates of mDFPS. We calculated the slope index of inequality (SII) and relative index of inequality (RII) as the measures of socioeconomic inequalities.ResultsA total of 782 639 women were surveyed. The response rate was 84.0% and above. The prevalence of mDFPS was below 50% in Maldives (22.8%, 95% CI 20.7 to 25.0), Pakistan (42.0%, 95% CI 39.9 to 44.0) and Afghanistan (39.1%, 95% CI 36.9 to 41.3), whereas Bangladesh had achieved 76% (75.8%, 95% CI 74.2 to 77.3). Both wealth and educational inequalities varied in magnitude and direction between the countries. Except in Nepal and Bangladesh, mDFPS wealth inequalities showed a trend of increasing mDFPS as we moved towards richer, and richest wealth quintiles that is, pro-poor (RII (0.5 to 0.9); SII (-4.9 to -23.0)). In India and Nepal, higher versus no education was in favour of no education (higher mDFPS among not educated women) (RII 1.1 and 1.4; SII 4.1 and 15.3, respectively) and reverse in other countries ((RII (0.4 to 0.8); SII (-10.5 to -30.3)). Afghanistan, Maldives and Pakistan fared badly in both educational and wealth inequalities among the countries.ConclusionsSouth Asia region still has a long way ahead towards achieving universal access to mDFPS. Diverse patterns of socioeconomic inequalities between the countries call for national governments and international development agencies to target the population subgroups for improving the mDFPS coverage.

Project description:ObjectivesThis study aimed to examine patterns and determinants of modern contraceptive discontinuation among women in Kenya.MethodsSecondary analysis was conducted using national representative Kenya Demographic and Health Surveys of 2003, 2008/9, and 2014. These household cross-sectional surveys targeted women of reproductive age from 15 to 49 years who had experienced an episode of modern contraceptive use within five years preceding the surveys from 2003 (n = 2686), 2008/9 (n = 2992), and 2014 (5919). The contraceptive discontinuation rate was defined as the number of episodes discontinued divided by the total number of episodes. Weighted descriptive statistics, multivariable logistic regression analysis, and Cox proportional hazards analysis were used to examine the determinants of contraceptive discontinuation.ResultsThe 12-month contraceptive discontinuation rate for all methods declined from 37.5% in 2003 and 36.7% in 2008/9 to 30.5% in 2014. Consistently across the three surveys, intrauterine devices had the lowest 12-month discontinuation rate (6.4% in 2014) followed by implants (8.0%, in 2014). In 2014, higher rates were seen for pills (44.9%) and male condoms (42.9%). The determinants of contraceptive discontinuation among women of reproductive age in the 2003 survey included users of short-term contraception methods, specifically for those who used male condoms (hazard ratio [HR] = 3.30, 95% confidence interval [CI] = 2.13-5.11) and pills (HR = 2.68; 95CI = 1.79-4.00); and younger women aged 15-19 year (HR = 2.07; 95% CI = 1.49-2.87) and 20-24 years (HR = 1.94; 95% CI = 1.61-2.35). The trends in the most common reasons for discontinuation from 2003 to 2014 revealed an increase among those reporting side effects (p = 0.0002) and those wanting a more effective method (p<0.0001). A decrease was noted among those indicating method failure (p<0.0001) and husband disapproval (p<0.0001).ConclusionsFamily planning programs should focus on improving service quality to strengthen the continuation of contraceptive use among those in need. Women should be informed about potential side effects and reassured on health concerns, including being provided options for method switching. The health system should avail a wider range of contraceptive methods and ensure a constant supply of commodities for women to choose from. Short-term contraceptive method users and younger women may need greater support for continued use.

Project description:IntroductionTobacco use among women, especially during pregnancy is a public health concern. There is a need to understand the diverse nature of their tobacco consumption across the globe.MethodsWe used Demographic and Health Surveys (DHS) data collected between 2010 and 2016 from 42 low- and middle-income countries (LMICs) to estimate the prevalence of smoking, smokeless tobacco, and dual use among pregnant and non-pregnant women of reproductive age (15-49 y). We compared tobacco use between both groups adjusted for age, type of residence, education and combined wealth index, and a subgroup analysis for the South-East Asia Region (SEAR) as the tobacco use in SEAR among women is far more diverse than in other regions primarily due to the popularity of smokeless tobacco use in this region.ResultsBased on the data of 1 310 716 women in 42 LMICs, the prevalence of smoking was 0.69%(95%CI: 0.51-0.90) among pregnant women and 1.09%(95%CI: 0.81-1.42) among non-pregnant women. The prevalence of smokeless tobacco use was 0.56%(95%CI: 0.33-0.84) among pregnant women and 0.78%(95%CI: 0.35-1.37) among non-pregnant women. The relative risk ratios(RRR) for smoking (0.85; 95%CI: 0.67-1.09) and smokeless tobacco use (0.81; 95%CI:0.67-1.00) were not-significantly lower among pregnant women than non-pregnant women and education and wealth index had an inverse relationship with both forms of tobacco. In SEAR, among pregnant women, the prevalence of smoking and smokeless tobacco use was 1.81% and 0.45%, respectively. However, pregnant women were 7%(RRR 1.07; 95%CI:1.02-1.12) more likely to use smokeless tobacco than non-pregnant women.ConclusionDespite the added risk of foetal harm during pregnancy, there is no evidence that the tobacco consumption between pregnant and non-pregnant women differ in 42 LMICs. A significantly higher use of smokeless tobacco among pregnant women in SEAR is of particular concern and warrants further investigation.ImplicationsTobacco use among women in low- and middle-income countries (LMICs) is lower than high-income countries (HICs), but this may be because LMICs are earlier in the epidemiological transition of tobacco use. If ignored as a public health issue and the tobacco industry continues to market its products to women, the level of tobacco use may rise as it did in HICs. Also, despite low prevalence rates and with no evidence that these differ among pregnant and non-pregnant women, is concerning as tobacco consumption in any form during pregnancy is associated with poor birth outcomes. This suggests a need for raising awareness about the harms of tobacco use among women in LMICs, especially during pregnancy. There is a need to develop preventive and cessation interventions to decrease tobacco use (smoking and smokeless) among women who are from low socio-economic status and less educated, as they bear the greatest burden of tobacco use.

Project description:BackgroundAccording to the 2017 estimate, around 214 million reproductive-age women in developing regions who want to avoid pregnancy do not use a modern contraceptive method. Although there are studies done on factors associated with modern contraceptive utilization in individual East African countries, as to our search of the literature, there is limited evidence on the pooled prevalence and determinants of modern contraceptive utilization in the East African region. Therefore, this study aimed to estimate the pooled prevalence and determinants of modern contraceptive utilization in the East African region.MethodsThe pooled prevalence of modern contraceptive utilization and the strength of determinants were estimated using STATA version 14. Intra-class Correlation Coefficient (ICC), Median Odds Ratio (MOR), Proportional Change in Variance (PCV), and deviance were used for model fitness and comparison. The multilevel logistic regression model was fitted to identify determinants of modern contraceptive use in the region. Adjusted Odds Ratio with its 95% Confidence Interval was presented, and variables with a p-value ≤of 0.05 were declared significant determinants of modern contraceptive utilization.ResultsOverall, about 20.68% (95%CI:-20.46.,20.91)of women used modern contraceptive, ranging from 9.08% in Mozambique to 61.49% in Comoros. In the multilevel logistic regression model; maternal age group 25-34 (AOR: 0.79, 95%CI:0.76,0.82) and 35-49 (AOR:0.49, 95%CI:0.46,0.51). Being married (AOR:0.85, 95%CI:0.82,0.88), mothers with primary education (AOR:1.48, 95%CI:1.43,1.54) and secondary and above education level (AOR:1.60, 95%CI:1.52,1.69), husbands with primary education (AOR:2.43, 95%CI:2.35,2.51) and secondary and above education level (AOR:2.92, 95%CI:2.76,3.05). The mothers who had occupation (AOR:2.11, 95%CI:1.23,1.33), mothers from households with middle wealth index (AOR:1.23, 95%CI:1.19,1.28) and rich wealth index (AOR:1.28, 95%CI:1.23,1.33) were found to be significant determinants of modern contraceptive use.ConclusionWe found that modern contraceptive utilization in the 12 East Africa countries was low compared to SDG target 2030(75%). The governmental and non-governmental organizations should scale up their public health programs to the poor and marginalized communities to scale up modern contraceptive utilization uptake in the region. In addition, reforming the health system and reproductive health education through mass media to create awareness of modern contraceptive use benefits are effective strategies to improve modern contraceptive use among East Africa women.

Project description:Reproductive health service is crucial for youth to reduce maternal and child mortality. However, many young women face unintended pregnancies and pregnancy-related complications due to insufficient knowledge of contraceptive methods and low contraceptive utilization. This study aims to assess the modern contraceptive prevalence rates among youth and identify factors influencing modern contraceptive utilization among youth. We used Myanmar Demographic and Health Survey (2015-2016) data. This study included 1,423 men and 3,677 women aged 15-24 years from all states and regions of Myanmar. We used multivariable binary logistic regression analysis and reported the results using adjusted Odds Ratios (AOR) with 95% Confidence Intervals (CI). Data analysis was done by STATA software (version 15.1). Ever-married youth used mainly injectable contraception, followed by oral contraceptive pills. Never-married male youth mainly used oral contraceptive pills; however, almost all never-married female youth did not use contraception. The modern contraceptive prevalence rates were 14.9% among total youth, 10% among males, 16.8% among females, 1.5% among never-married males, 44.7% among ever-married males, and 54% among ever-married female youth. The knowledge on modern contraceptive methods favored the utilization. Sexually active youth utilized more contraception than sexually inactive youth. We also found geographical variation and low utilization among rural youth. The desire for more children was also a significant predictor of contraceptive utilization among married youth. The utilization of modern contraception was low among Myanmar youth. Reproductive health program needs to be emphasized on the youth population especially in the area with low utilization to have equitable access to quality reproductive health services. Moreover, the revitalization of Youth Information Corner and youth-friendly reproductive health education programs should be implemented to increase reproductive health knowledge and prevent unsafe sex, unintended pregnancies, and abortions which might help in reducing maternal and child mortality. We warranted conducting mixed method studies to explore the barriers and challenges of contraceptive utilization and male involvement in the choice of contraception among youth.

Project description:BackgroundFollowing the successful implementation of the Millennium Development Goals (MDGs) strategy in Tanzania, improvements in child health indicators were observed. However, it remains unclear whether complementary feeding practices have improved given the renewed global agenda on child nutrition. This study investigated trends and socioeconomic and health service factors of complementary feeding practices in Tanzania for the period spanning from 2004 to2016.MethodsThe study was based on the Tanzania Demographic and Health Survey data for the years 2004-2005 (n?=?2480), 2010 (n?=?2275) and 2015-2016 (n?=?2949) to estimate the trends in complementary feeding practices. Multivariate logistic regression models that adjusted for year of the survey, clustering and sampling weights were used to investigate the association between the modifiable study factors (socioeconomic and health service factors) and complementary feeding practices among children aged 6-23 months in Tanzania.ResultsOver the study period, minimum dietary diversity (MDD) and minimum acceptable diet (MAD) have worsened from 46% (95% confidence interval [95% CI] 41.5-50.7%) in 2004-2005 to 30% (95% CI 25.7-32.9%) in 2015-2016 and 16.9% (95% CI 14.9-18.9%) in 2004-2005 to 6.0% (95% CI 4.9-7.1%) in 2015-2016, respectively. Minimum meal frequency (MMF) remained unchanged, 37% in 2004-2005 and 2015-2016. The introduction of solid, semi-solid and soft foods improved from 79% (95% CI 74.5-83.9%) in 2004-2005 to 87% (95% CI 83.7-90.9%) in 2015-2016. Multivariate analyses revealed that higher maternal education and household wealth, mother's employment, health facility birthing and postnatal care (PNC) visit were associated with MDD, MAD and MMF. Traditional birth attendant-assisted births and PNC visits were associated with the introduction of complementary foods. In contrast, birthing in the health facility was associated with the delayed introduction of complementary foods.ConclusionBetween 2004 and 2016, the prevalence and determinants of complementary feeding practices varied in Tanzania. Improving complementary feeding practices is feasible in Tanzania given the renewed focus on child nutrition in the country. Child nutrition policy interventions should target all mothers, particularly mothers from low socioeconomic background and those with limited access to health services to maximise results.
