Childhood Obesity and Overweight in Ghana: A Systematic Review and Meta-Analysis

الملخص EN

The increasing prevalence of childhood obesity and overweight is considered a public health issue in both developed and developing countries.

This systematic review and meta-analysis estimates the prevalence of childhood obesity and overweight in Ghana.

A multiple database search was conducted for articles published between January 1, 2001, and October 31, 2019, reporting the prevalence of childhood obesity and overweight in Ghana.

Databases searched include PubMed, Google Scholar, Scopus, Cochrane Library, World Health Organization (WHO) Library Information System, and Africa Journals Online.

Data were pooled from the articles to calculate an overall estimate of childhood obesity and overweight using a random-effects model after variance stabilization with Freeman–Tukey double arcsine transformation.

This review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Sixteen studies with a combined sample size of 29,160 were included in the review.

Analysis indicates that approximately 19% of children in Ghana either have obesity or are overweight.

The prevalence of childhood obesity and overweight was 8.6% (95% CI: 4.8%–13.4%) and 10.7% (95% CI: 5.9%–16.6%), respectively.

Although not significant, higher obesity (4.6% vs.

2.6%) and overweight (11.0% vs.

7.2%) prevalence were estimated for females than for males.

There was a significantly higher obesity prevalence estimate (17.4% vs.

8.9%) in rural settings than in urban settings (p=0.0255).

The high prevalence of childhood obesity and overweight estimated in this review is of worrying concern.

It is a significant public health problem that has implications on the health of present and future generations in Ghana and as such calls for proactive measures to be put in place.

Also, the driving forces behind the increasing prevalence of childhood obesity in Ghana need to be investigated.
