High-risk fertility behaviour and undernutrition among children under-five in sub-Saharan Africa: a cross-sectional study

OBJECTIVE

The study examined high-risk fertility behaviour and its association with under-five undernutrition in sub-Saharan Africa (SSA).

DESIGN

We conducted a cross-sectional analysis of data from 32 sub-Saharan African countries' Demographic and Health Surveys. A weighted sample of 110 522 mother-child pairs was included in final analysis. Multilevel binary logistic regression was used to examine the association between high-risk fertility behaviour and undernutrition. The results were presented using adjusted odds ratio (aOR) with their respective 95% confidence intervals (CIs).

SETTING

Thirty-two countries in SSA.

OUTCOME MEASURE

Stunting, wasting, and underweight.

RESULTS

The pooled prevalence of stunting was 31.3%, ranging from 15.0% in Gabon to 51.7% in Burundi. Wasting was highest among children from Burkina Faso (19.1%) and lowest among those from South Africa (1.6%). The overall prevalence of wasting was 8.1%. The prevalence of underweight was 17.0%, with the highest among children in Niger (37.1%) and lowest in South Africa (4.8%). Mothers who gave birth at the age less than 18 years and those with short birth interval were more likely to have their children being stunted, wasted, and underweight. The odds of stunting and wasting were high among children born to women with high parity. However, maternal age at birth more than 34 was associated with lower odds of childhood underweight as against those with age at birth less than 34.

CONCLUSION

Countries in SSA are encouraged to address the issue of maternal age at birth less than 18, high parity, and shorter birth intervals in order to meet the Global Nutrition targets, which aim to achieve a 40% reduction in the number of stunted children under the age of 5 and to reduce and maintain childhood wasting to less than 5% by 2025.

Association of breastfeeding with undernutrition among children under 5 years of age in developing countries: A systematic review and meta-analysis

OBJECTIVE

This meta-analysis was conducted to examine the association between breastfeeding and undernutrition among children under 5 years of age in developing countries.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A comprehensive literature search was conducted of datasets from Embase, CINHAL, PubMed, Cochrane Library, and Indonesian databases to include eligible studies. Comprehensive Meta-Analysis 3.0 statistical software was used to perform data entry and data analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were extracted from each study or were calculated based on the reported number of cases and controls in each study. Random-effects models or fixed-effects models were used to demonstrate overall risk estimates. A moderator analysis was conducted to examine possible moderators explaining the heterogeneity across studies.

FINDINGS

In total, 33 studies were included which examined the association of breastfeeding with undernutrition. A random-effects model showed that breastfeeding had inverse correlations with overall undernutrition (OR = 0.82, 95% CI = 0.68, 0.99) and the stunting type of undernutrition (OR = 0.73, 95% CI = 0.55, 0.95). A moderator analysis showed that studies which included exclusive breastfeeding and unclear birth weights had low risks of overall undernutrition (p < 0.05). Moreover, studies which included exclusive breastfeeding and adopted a case-control study design exhibited a low risk of the stunting type of undernutrition (p < 0.05).

CONCLUSIONS

Providing breastfeeding or exclusive breastfeeding can benefit children under 5 years of age in developing countries reduce overall undernutrition and the stunting type of undernutrition.

CLINICAL RELEVANCE

Healthcare professionals should develop and implement suitable strategies to increase awareness regarding the importance of breastfeeding and enhance breastfeeding and exclusive breastfeeding adherence.
