Maternal socio-demographic factors associated with low parity and grand multiparity in Nigeria

Association of Parity With Insulin Resistance Early in Pregnant Women: ECLIPSES Study

CONTEXT

Little is known about whether parity is associated with elevated early-pregnancy insulin resistance (IR), or whether overweight/obesity contributes to increasing the possible effect.

OBJECTIVE

We determined the associations between parity and glucose metabolism parameters in the first trimester of pregnancy in a Mediterranean pregnant population, and whether these associations are affected by overweight/obesity.

METHODS

A cross-sectional study was conducted of 264 healthy pregnant women from the ECLIPSES study who were recruited at 12 weeks of gestation. At baseline, details on socioeconomic status, obstetric history (including parity, ie, number of births), lifestyle factors, anthropometry, and blood samples were collected. Fasting serum glucose, insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed in the first trimester. Elevated IR was defined as the upper HOMA-IR tertile (≥1.58). Multivariable linear regression and Cox regression model with constant time were performed.

RESULTS

Parity ranged from 0 to 4. After multivariable adjustment, the insulin levels (β [% change]: 20.92; 95% CI, 4.08-37.71) and HOMA-IR index (β [% change]: 19.72; 95% CI, 2.43-40.49) were positively associated with parity. Additionally, multiparous women, as compared to nulliparous, were more likely to have higher HOMA-IR levels (primiparous [1 birth], β [% change[: 16.88; 95% CI, -1.00 to 37.99; multiparous [≥2 births), β [% change]: 32.18; 95% CI, 3.56-68.71), and an increased relative risk (RR) of an elevated IR (primiparous [1 birth], RR: 1.55; 95% CI, 1.03-2.36; multiparous (≥2 births), RR: 1.72; 95% CI, 1.05-2.83). The combination of multiparity and overweight/obesity conferred a 3.04-fold increase in the RR of elevated IR, which increased proportionally to the number of parities.

CONCLUSION

This study demonstrates that parity may have a negative effect on early-pregnancy IR and that maternal overweight/obesity appears to further aggravate this relationship.

Women's ability to negotiate safer sex with partners by contraceptive status among a nationally representative sample of married women in Nigeria

BACKGROUND

Existing studies established that safer sex negotiation influences contraceptive use, and women who are able to negotiate safer sex were expected to be contraceptive users. However, it is not certain that all contraceptive users have the ability to negotiate safer sex. Likewise, there is no evidence that all non-users are not able to negotiate safer sex with partners. The study assesses the prevalence of women's ability to negotiate safer sex and examines the determinants of women's ability to negotiate safer sex among contraceptive users and non-users.

METHODS

The comparative cross-sectional research design was adopted. Data were extracted from the 2018 Nigeria Demographic and Health Survey. The study analyzed a sample of 2,765 contraceptive users and 20,304 non-users. The outcome variable was women's ability to negotiate safer sex with partners. The explanatory variables examined are eight socio-demographic characteristics (age, child marriage, education, parity, media exposure, religion, work status, and experience of female genital mutilation), six relational characteristics (healthcare autonomy, financial autonomy, household wealth quintile, partners' education, ownership of assets, and type of marriage). Attitude to wife-beating, male controlling behavior, place of residence, and geo-political zone of residence were included as control variables. Multivariable regression models were estimated.

RESULTS

Findings showed that 6.2% of women who were not able to negotiate safer sex were contraceptive users, while 15.9% of women who were able to negotiate safer sex were contraceptive users. Among non-users, the significant determinants were child marriage, education, parity, mass media exposure, religion, work status, healthcare autonomy, financial autonomy, household wealth, partner education, type of marriage, geo-political zone, attitude to wife-beating, and male controlling behavior. Regarding contraceptive users, the significant determinants were parity, religion, the experience of female genital mutilation, financial autonomy, partner education, type of marriage, and the geo-political zone of residence.

CONCLUSION

The ability to negotiate safer sex differs among contraceptive users and non-users. Also, the determinants of the ability to negotiate safer sex differ among contraceptive users and non-users. While existing strategies may continue to focus on women not using contraceptives, new strategies promoting reproductive autonomy are required among contraceptive users.

Education and Intimate Partner Violence Among Married Women in Nigeria: A Multilevel Analysis of Individual and Community-Level Factors

Research has documented an inverse relationship between lifetime intimate partner violence (IPV) and a woman's educational accomplishment. Moreover, women without formal education were more likely to report lifetime IPV in comparison with women who completed more than 12 years of education. Therefore, this study examines the individual and community-level factors that determine the degree of IPV vis-à-vis women's education. Data set of currently married women were extracted from 2018 Nigeria Demographic and Health Survey. The study employed three levels of statistical analysis. The result of the analysis reveals that the nature of IPV differs due to women's educational status. Women with the highest level of education experienced the least of all the three IPV indicators identified in this study. A significant relationship exists with women's education and ever experienced physical violence (primary odds ratio [OR] = 1.29; secondary OR = 1.44, higher OR = 0.71). The ORs of ever experienced sexual violence decrease as women's education increases (secondary OR = 1.10, higher OR = 0.63). The higher significant effect of husband/partner who drinks alcohol on all the three indicators of IPV was affirmed (p < .01). Except for community labor participation, all other community variables were significant with emotional violence and sexual violence (p < .05). The study established that both individual and community factors influence the incidence of IPV in the study area. The study concludes that women empowerment alone cannot reduce the incidence of IPV as revealed in the study; community sensitization about the consequences of IPV on the health of women and the well-being of the family should be intensified.

Prevalence and determinants of unmet need for contraception among women in low and high-priority segments for family planning demand generation in Nigeria

BACKGROUND

Studies have identified various determinants of unmet need for contraception. These determinants cut across individual, household, community, and health facility levels. Despite this evidence, there remains a lack of information regarding differentials in the prevalence and determinants of unmet need for contraception among women in the low-priority segments (such as women of advanced reproductive age and women living with disabilities) and high-priority segments (such as adolescents, young adults, and unmarried women) for family planning demand generation, hence this study.

METHODS

The study design is cross-sectional. The study analyzed merged data from the individual, and persons recode of the 2018 Nigeria Demographic and Health Survey (NDHS). The samples analyzed are 5,147 women in the high-priority segment and 7,536 women in the low-priority segment. The outcome variable in the study was unmet need for contraception. The explanatory variables were selected at the individual, household, community, and facility levels. Statistical analyzes were performed using Stata 14. Three multilevel mixed-effects regression models were fitted. Model 1 was the empty model, while Model 2 included the sets of individual, household, and community variables. Model 3 controlled for the facility-level variables.

RESULTS

Findings show a higher prevalence of unmet need for contraception among women in the family planning low-priority segment compared to women in the family planning high-priority segment. Religion and desired family size were the two individual characteristics that significantly predicted the unmet need for contraception among women in the two segments. Sexual autonomy was the only household characteristic that predicted unmet need for contraception in both segments. There were differences in the community characteristics that predicted unmet need for contraception among women in the two segments.

CONCLUSION

The prevalence of unmet need for contraception is not the same among women in low and high family planning priority segments. The determinants also differ among women in the two segments. Though, women in different family planning segments have the same contraceptive needs of avoiding pregnancy when not needed, however, getting the needs satisfied requires that existing programs be further examined to develop initiatives that will resonate with each segment of reproductive-age women.

The health consequences of child marriage: a systematic review of the evidence

Background

Child marriage, defined as marriage before 18 years of age, is a violation of human rights and a marker of gender inequality. Growing attention to this issue on the global development agenda also reflects concerns that it may negatively impact health. We conducted a systematic review to synthesize existing research on the consequences of child marriage on health and to assess the risk of bias in this body of literature.

Methods and findings

We searched databases focused on biomedicine and global health for studies that estimated the effect of marrying before the age of 18 on any physical or mental health outcome or health behaviour. We identified 58 eligible articles, nearly all of which relied on cross-sectional data sources from sub-Saharan Africa or South Asia. The most studied health outcomes were indicators of fertility and fertility control, maternal health care, and intimate partner violence. All studies were at serious to critical risk of bias. Research consistently found that women who marry before the age of 18 begin having children at earlier ages and give birth to a larger number of children when compared to those who marry at 18 or later, but whether these outcomes were desired was not considered. Across studies, women who married as children were also consistently less likely to give birth in health care facilities or with assistance from skilled providers. Studies also uniformly concluded that child marriage increases the likelihood of experiencing physical violence from an intimate partner. However, research in many other domains, including use of contraception, unwanted pregnancy, and sexual violence came to divergent conclusions and challenge some common narratives regarding child marriage.

Conclusions

There are many reasons to be concerned about child marriage. However, evidence that child marriage causes the health outcomes described in this review is severely limited. There is more heterogeneity in the results of these studies than is often recognized. For these reasons, greater caution is warranted when discussing the potential impact of child marriage on health. We provide suggestions for avoiding common biases and improving the strength of the evidence on this subject.

Trial registration

Parity and the risk of incident dementia: a COSMIC study

AIMS

To investigate the association between parity and the risk of incident dementia in women.

METHODS

We pooled baseline and follow-up data for community-dwelling women aged 60 or older from six population-based, prospective cohort studies from four European and two Asian countries. We investigated the association between parity and incident dementia using Cox proportional hazards regression models adjusted for age, educational level, hypertension, diabetes mellitus and cohort, with additional analysis by dementia subtype (Alzheimer dementia (AD) and non-Alzheimer dementia (NAD)).

RESULTS

Of 9756 women dementia-free at baseline, 7010 completed one or more follow-up assessments. The mean follow-up duration was 5.4 ± 3.1 years and dementia developed in 550 participants. The number of parities was associated with the risk of incident dementia (hazard ratio (HR) = 1.07, 95% confidence interval (CI) = 1.02-1.13). Grand multiparity (five or more parities) increased the risk of dementia by 30% compared to 1-4 parities (HR = 1.30, 95% CI = 1.02-1.67). The risk of NAD increased by 12% for every parity (HR = 1.12, 95% CI = 1.02-1.23) and by 60% for grand multiparity (HR = 1.60, 95% CI = 1.00-2.55), but the risk of AD was not significantly associated with parity.

CONCLUSIONS

Grand multiparity is a significant risk factor for dementia in women. This may have particularly important implications for women in low and middle-income countries where the fertility rate and prevalence of grand multiparity are high.

Rising cesarean deliveries in India: medical compulsions or convenience of the affluent?

From 2005-06 to 2015-16, proportion of cesarean deliveries in total deliveries has almost doubled in India. In this paper, we study changes in prevalence of cesarean deliveries across different social-economic groups and study factors affecting odds of undergoing cesarean delivery. The present paper was based on National Family Health Surveys and employs logistic regression. We find that rise in cesarean deliveries has been across social groups, religions, urban/rural India, wealth groups, though increase has not been uniform. Further, many economically affluent states have high proportion of cesarean deliveries. We find that women delivering at private hospitals had significantly higher odds of opting for cesarean delivery. Further, women belonging to rich households were more likely to go through surgery for birth. In case of earlier terminated pregnancies, odds were higher too. The higher odds of cesarean sections in the relatively affluent geographic regions, richer households and private institutions indicate that these procedures may be driven by non-medical reasons in many cases, pointing toward the use of surgical procedures for the convenience.
