Socio-demographic factors associated with delayed childbearing in Nigeria

Determinants of Utilization of Antenatal Care Services Among Women of Childbearing Age in Jigawa State, Nigeria

Introduction

Antenatal care (ANC) services play a crucial role in safeguarding the health of pregnant women during their reproductive years. This study aimed to evaluate the primary factors influencing the utilization of ANC among women of childbearing age in Isari town, Jigawa State.

Methods

We conducted a cross-sectional study among 400 mothers of childbearing age, selecting them using a simple random sampling method. Data were collected using interviewer-administered questionnaires. The statistical analyses performed were descriptive analysis, Pearson's chi-square test, and binary logistic regression analysis.

Results

The majority of respondents (92.5%) indicated awareness of ANC, with a significant proportion expressing the necessity of ANC services (85.7%). 57.8% of the respondents indicated attending ANC services at least four times during pregnancy. Furthermore, the number of visits has a significant relationship with age (P < 0.001), educational level (P = 0.003), occupation (P = 0.043), mother's knowledge of pregnancy danger signs (P = 0.001), and husband's support for ANC (P < 0.001).

Conclusion

Enhancing ANC utilization will necessitate focusing on women residing in rural areas and those with limited educational attainment.

Global, regional, and national burden of premenstrual syndrome, 1990-2019: an analysis based on the Global Burden of Disease Study 2019

STUDY QUESTION

What is the burden of premenstrual syndrome (PMS) at the global, regional, and national levels across 21 regions and 204 countries and territories?

SUMMARY ANSWER

Over the past few decades, the global prevalent cases of PMS have grown significantly from 652.5 million in 1990 to 956.0 million in 2019, representing a 46.5% increase.

WHAT IS KNOWN ALREADY

PMS, which affects almost half of reproductive women worldwide, has substantial social, occupational, academic, and psychological effects on women's lives. However, no comprehensive and detailed epidemiological estimates of PMS by age and socio-demographic index (SDI) at global, regional, and national levels have been reported.

STUDY DESIGN, SIZE, DURATION

An age- and SDI-stratified systematic analysis of the prevalence and years lived with disability (YLD) of PMS by age and SDI across 21 regions and 204 countries and territories has been performed.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The prevalence and YLD of PMS from 1990 to 2019 were retrieved directly from the Global Burden of Diseases (GBD) 2019 study. The number, rates per 100 000 persons, and average annual percentage changes (AAPCs) of prevalence and YLD were estimated at the global, regional, and national levels.

MAIN RESULTS AND THE ROLE OF CHANCE

Globally, the prevalent cases of PMS increased by 46.5% from 652.5 million in 1990 to 956.0 million in 2019; in contrast, however, the age-standardized prevalence rate was approximately stable at 24 431.15/100 000 persons in 1990 and 24 406.51/100 000 persons in 2019 (AAPC, 0[95% CI: -0.01 to 0.01]). Globally, the YLD was 8.0 million in 2019 and 5.4 million in 1990, with a sizable increase over the past 30 years. The age-standardized YLD rate was stable (AAPC 0.01, P = 0.182), at 203.45/100 000 persons in 1990 and 203.76/100 000 persons in 2019. The age-standardized burden estimates were the highest in the low-middle SDI regions and the lowest in the high SDI regions. Peaks in burden rate estimates were all observed in the 40-44 years age group. Regional age-standardized burden estimates were the highest in South Asia and the lowest in Western Sub-Saharan Africa. The national age-standardized burden estimates were the highest in Pakistan and the lowest in Niger.

LIMITATIONS, REASONS FOR CAUTION

The accuracy of the results depended on the quality and quantity of the GBD 2019 data. Fortunately, the GBD study endeavoured to retrieve data globally and applied multiple models to optimize the completeness, accuracy, and reliability of the data. In addition, the GBD study took the country as its basic unit and neglected the influence of race. Further study is warranted to compare differences in PMS burden associated with race. Finally, no data are available on the aetiology and risk information related to PMS, which might help us to better understand the trends and age distribution of PMS and help local governments formulate more detailed policies and comprehensive interventions.

WIDER IMPLICATIONS OF THE FINDINGS

Although the age-standardized prevalence/YLD rate has been stable over the past 30 years, the absolute number of prevalent cases and YLD grew significantly worldwide from 1990 to 2019. Public health-related policies should be implemented to reduce the prevalence and alleviate the symptoms of PMS. Lifestyle changes and cognitive-behavioral therapy are critical in helping to reduce the burden of PMS.

Secular trends of birthweight in a population of live-born, singletons, without congenital anomalies in Queensland, Australia

Objectives and importance

Maternal and family patterns are changing, and these changes can influence birthweight. Past research and organisational reports focus on short temporal timelines or broad trends, but trends across a longer temporal period are important. The aim of this study is to assess the trends in birthweight and maternal characteristics across a 19-year period using descriptive statistics.

Study type and methods

Birth records (n = 1,166,055) were obtained for a 19-year period (2000–2019) and a descriptive secular trend analysis was performed.

Results and conclusions

Mean birthweight trended down across the study period, while rates of large for gestational age births increased. This appears to be driven by a decrease in gestational age across the period. Maternal factors, such as smoking, BMI and Indigenous status, were found to be linked with changes in mean birthweight and the proportion of small for gestational age or large for gestational age. More babies were born to older women by the end of the study period. There was a sharp rise in gestational diabetes, and more large for gestational age births to these women. Over time, the large for gestational age births started to decline, suggesting better care practices for women with gestational diabetes.

Unrealized fertility among women in low and middle-income countries

Background

There has been little research on women who have fewer than their ideal number of children toward the end of their childbearing years in low and middle-income countries (LMICs). We examine the level and distribution of unrealized fertility in LMICs across three geographical regions. We also examine the role of sex preference and other factors associated with unrealized fertility.

Data and methods

We used Demographic and Health Survey (DHS) data for women age 44–48 in 36 countries from the three geographical regions of Western and Central Africa, Eastern and Southern Africa, and South and Southeast Asia. We conducted descriptive analysis to examine the distribution of unwanted fertility and unrealized fertility, and fit adjusted logistic regressions of unrealized fertility. The main variables are number of living children (including by sex) and the sex composition of children. Other variables included education, marital status, age at first childbirth, wealth quintile, place of residence, exposure to family planning messages, contraceptive use, and country.

Results

Unrealized fertility was highest in Western and Central Africa, followed by Eastern and Southern Africa. In all regions, there was a decrease in unrealized fertility with an increasing number of children. Findings for sex preference varied with little sex preference in the African regions, and some limited evidence of preference for sons in South and Southeast Asia. In most regions, higher levels of education, higher wealth quintile, and use of contraceptive methods were associated with decreased unrealized fertility.

Conclusion

Family planning programs and messages should consider regional and socioeconomic differences in unrealized fertility in order to give women and families the right to achieve the family size they desire regardless of their status.

Impact of maternal age on neonatal outcomes among very preterm infants admitted to Chinese neonatal intensive care units: a multi-center cohort study

BACKGROUND

The percentage of advanced maternal age (aged over 35 years) mothers has been rising across the world, the evidence of maternal age on neonatal outcomes from low- and middle-income countries is scarce. Our objective was to evaluate the effect of maternal age on mortality and major morbidity among very preterm infants admitted to Chinese neonatal intensive care units.

METHODS

Data from a retrospective multi-center cohort of all complete care very preterm infants admitted to 57 neonatal intensive care units that participated in the Chinese Neonatal Network from January 1st to December 31st, 2019 were analyzed. Neonatal outcomes including mortality or any major morbidity, defined as necrotizing enterocolitis stage 2 or 3, moderate & severe bronchopulmonary dysplasia, severe intraventricular hemorrhage, cystic periventricular leukomalacia, severe retinopathy of prematurity, or sepsis. A multiple logistic regression model was constructed to analyze the independent association between maternal age and neonatal outcome.

RESULTS

Among 7,698 eligible newborns, 80.5% of very preterm infants were born to mothers between the ages of 21 and 35 years, with 18.0% born to mothers >35 years and 1.5% born to mothers <21 years. Higher rates of maternal hypertension, maternal diabetes, cesarean deliveries, antenatal steroid usage were noted as maternal age increased. The proportion of prenatal care, cesarean section, antenatal steroid usage and inborn for very preterm infants born to mothers <21 years was lower than those of mothers of other ages. Compared to the ages of 21-35 years group, the odds of severe intraventricular hemorrhage (adjusted odd ratio: 2.00, 95% CI: 1.08-3.71) was significantly higher in the ages of 15-20 years group. Increasing maternal age was associated with higher rates of small for gestational age and lower birth weight of very preterm infants, but no correlation between advanced maternal age and very preterm infants mortality or major morbidity.

CONCLUSIONS

Among very preterm infants, increasing maternal age was associated with higher rates of small for gestational age but not neonatal mortality or major morbidity. Young maternal age may increase the risk of severe intraventricular hemorrhage of very preterm infants.

Association between maternal age and adverse perinatal outcomes in Arba Minch zuria, and Gacho Baba district, southern Ethiopia: a prospective cohort study

Background

Globally, delayed childbearing to the advanced age is a growing option. It is an emerging public health issue in developing countries. Currently, adverse perinatal outcomes significantly increased. A few studies showed the effect of advanced maternal age on adverse perinatal outcomes. However, most used secondary data or chart reviews, and this increases the risk of biases. Besides, there are limited studies in-country Ethiopia as advanced maternal age steadily increased. Therefore, this study aimed to assess the status of advanced maternal age and its effect on perinatal outcomes in the study setting.

Methods

A community-based prospective cohort study was conducted among 709 study participants from October 15, 2018, to September 30, 2019, in Arba Minch zuria, and Gacho Baba district, southern Ethiopia. The data were collected by a pretested interviewer-administered structured Open Data Kit survey tool and analyzed by SPSS version 25. The log-linear regression model was used to compare perinatal outcomes among women aged 20–34 years and ≥ 35 years. The log-likelihood ratio tested for the goodness of fit. In this study, P-value < 0.05 was considered to declare a result as a statistically significant association.

Results

In this study, 209(29.5%) of the women were age group ≥35 years old, and 500(70.5%) were age group from20–34 years old. Stillbirth (β = 0.29, 95%CI: 0.05, 0.52), and neonatal mortality (β = 0.11, 95%CI: 0.01, 0.21) were significantly associated with the advanced maternal age.

Conclusions

Perinatal outcomes such as stillbirth and neonatal mortality were independently associated with advanced maternal age after controlling for possible cofounders. Therefore, different strategies should design for the women who planned to bear child, and information should provide for women who are advanced age or delayed childbearing to alert them.
