Obesity in adults has between 1975 and 2016 across the world. The World Health Organization that by 2016, about 1.9 billion adults worldwide were overweight. More than 650 million of these adults were obese. These represent about 39% and 13% of the world's adult population, respectively.
Women bear a disproportionately higher burden of obesity. In 2016, it was that 15% of the world's women and 11% of men were obese.
Overweight and obesity are burgeoning health issues in sub-Saharan Africa – particularly South Africa, with a significantly high burden of overweight and obesity.
In our we looked at the prevalence of overweight and obesity among women of childbearing age in South Africa. Earlier studies published in , and (including a government report) show the prevalence of overweight and obesity at one single point in time. But there is a dearth of studies looking at trend data on overweight and obesity prevalence among women of childbearing age, including socioeconomic determinants.
Obesity leads to a number of . These include infertility, miscarriage, babies having congenital abnormalities and other adverse obstetric outcomes. Women who are super-obese experience (hypertension, pre-eclampsia and surgical complications) than those who are morbidly obese. Noncommunicable diseases associated with obesity are among the in the country.
Overweight and obesity
looked at nationally representative data on the prevalence and determinants of overweight and obesity in South African women aged 15 to 49 who were not pregnant. It covered the period 1998 to 2017.
The study found a rise in the prevalence of overweight (from 51.3% to 60%) and obesity (from 24.7% to 35.2%) between 1998 and 2017.
There are a number of factors behind the rising trend of overweight and obesity in women of childbearing age in South Africa. These include rapid economic development since the new democracy in 1994, urbanisation, and the increased number of women in the labour force.
Working women tend to have low-energy expending jobs. And mobility is less energy-intensive because of shorter commutes and the use of motorised transport. Long working hours make it difficult for many women to prepare healthy meals. In addition, processed food is more widely accessible. Also, the wider living environment may act as a barrier to physical activity. High crime levels in communities can lead to safety concerns that prevent women from being physically active.

Factors associated with being overweight and obese were: increased age; self-identifying with the black African population group; higher educational attainment; residing in an urban area; and belonging to wealthier socioeconomic quintiles. Current smokers had decreased odds of being overweight and obese.
The prevalence of obesity in South Africa is high relative to that documented in other countries (except for urban Egypt). Rates of overweight and obesity documented in the , and vary between 10% and 32%.
Our findings show that South Africa is off-track with meeting targets it set in 2013 for reducing overweight and obesity levels. The initial goal was to get levels down .
Given that by the levels of overweight and obesity were still at 60% and 35.2%, respectively, it is clear from this research that more needs to be done.
Recommendations
The current tax on sugar-sweetened beverages is an example of the government's commitment to fighting obesity in South Africa. However, the rising prevalence of overweight and obesity among women of childbearing age reported in this research means the government needs to complement this tax with other interventions.

The government should run sensitisation and awareness-raising campaigns and programmes targeting certain groups of women. There is a need to focus on women who are older, who self-identify as black African, with higher educational attainment, who live in urban areas, and who are relatively wealthy.
In addition, the interests of the food industry that contribute to the rise in overweight and obesity need to be regulated. And investments must be made by the government to promote healthy lifestyles and safety in urban communities. At an individual level, women need to have healthy lifestyles and be physically active. This will help to reverse or restrain the rise in overweight and obesity.
