Africa faces diabetes crisis, study finds
Researchers warn that type 2 diabetes could affect millions more people in the coming decades after a study published this month revealed the disease is rising far faster among people in sub-Saharan Africa than previously thought.
Take 51-year-old security guard Sibusiso Sithole, for example. Being diagnosed with type 2 diabetes came as a shock, he said, because he walked six miles to and from work every day and never thought his weight was a problem.
Then his wife noticed changes in his health.
Since his diagnosis 13 years ago, Sithole has been on a rigorous treatment for diabetes and high blood pressure.
'I have to take six ... medications every day,' he said.
Diabetes is a condition in which the body struggles to turn food into energy due to insufficient insulin. Without insulin, sugar stays in the blood instead of entering cells, leading to high blood-sugar levels. Long-term complications include heart disease, kidney failure, blindness and amputations.
The International Diabetes Federation estimated in 2021 that 24 million adults in sub-Saharan Africa were living with the condition. Researchers had projected that by 2045, about 6% of sub-Saharan Africans — over 50 million — would have diabetes.
The new study, published this month in the medical journal The Lancet, suggested the actual percentage could be nearly double that.
By tracking more than 10,000 participants in South Africa, Kenya, Ghana and Burkina Faso over seven years, researchers found that poor eating habits, lack of health care access, obesity and physical inactivity are key drivers of diabetes in Africa.
Dr. Raylton Chikwati, a study co-author from the University of Witwatersrand in South Africa, said another risk factor is living in or moving to the outskirts of cities, or 'peri-urban areas.'
'Access to health care, you know, in the rural areas is a bit less than in the urban areas,' Chikwati said, adding that increased use of processed foods in the peri-urban areas was a problem.
Palwende Boua, a research associate at the Clinical Research Unit of Nanoro in Burkina Faso, said long-term studies are rare in Africa but essential to understanding diseases.
'Being able to have a repeated measure and following up [with] the same people ... is providing much more information and much valuable information,' Boua said, 'rather than having to see people once and trying to understand a phenomenon.'
Boua is preparing a policy brief for Burkina Faso's government to assist in the fight against diabetes.
For Sithole, managing his diabetes has been a long journey. But with treatment and lifestyle changes, he has regained control over his health.
'What I can tell people is that they must go and check — check the way they eat — because that time I was having too much weight in my body,' he said. 'I was wearing size 40 that time. Now I'm wearing size 34.'
Experts stressed that Africans should get their blood-sugar level tested and seek treatment when diabetes is diagnosed.

Namibia doctors fight cervical cancer
The cervical cancer rate in Namibia is 37.5 for every 100,000 women, about three times higher than the rate worldwide. Cervical cancer is one of the most preventable cancers and doctors in Namibia are advocating greater access to healthcare and the HPV vaccine to reduce the prevalence of the disease. November 2009 was a turning point in the life of Barbara Kamba-Nyathi. At the tender age of 29, she was diagnosed with stage three cervical cancer. Her doctors recommended radiation therapy as opposed to chemotherapy, because at that time she had not yet had children and radiation therapy would help her avoid premature menopause. But that was not her only struggle. Kamba-Nyathi, who lived in Windhoek at the time, said she faced stigma for cervical cancer's association with HIV and the human papilloma virus. "One of the challenges that come with having a diagnosis like cervical cancer is that our African society its usually taboo to talk about things of our reproductive organs, you know, our reproductive system is taboo," said Kamba-Nyathi. "We don't talk about such things and in the end, we tend to normalize pain and even things that don't feel right in our bodies we tend to normalize them and they become part of our identity." Rolf Hansen, the chief executive officer of the Cancer Association of Namibia, said a lack of education and a lack of access to healthcare prevent many women from getting tested or being treated for cervical cancer or HPV, which is the second-leading cause of cancer among sub-Saharan women. "Like I said, HIV and HPV work hand in hand to fuel the cervical cancer pandemic," said Hansen. "Now, in our country as well we see that in our low-income setting as well as our rural setting, we have high HPV prevalence, high cervical cancer so a lot of work needs to be done at a grassroots level so that we can actually combat this disease." Doctors Simon and David Emvula provide health services to underprivileged communities, together with the Be Free/Break Free program — an initiative of former first lady Monica Geingos — in Namibia's largest township of Katutura. They are advocating for the rollout of the HPV vaccine for girls between the ages of 9 and 14, before they become sexually active. Emvula said that during one screening in Windhoek on Saturday, they treated more than 100 patients, screening girls and women for HPV, cervical cancer, fibroids and other sexually transmitted infections and sexually transmitted diseases. Emvula spoke to VOA at his practice in Windhoek. "The turnout was actually beyond what we expected and once again it was an eye-opener ... that there is definitely a need for that," said Emvula. Emvula said HPV vaccination is among the most effective ways to prevent cervical cancer but the government of Namibia is lagging. HPV vaccines have been introduced in 129 countries worldwide and the Namibian government has endorsed the rollout of the vaccines for girls ages 9 to 14. Despite promises made as reported by VOA last year, the vaccines have not yet been made available. Namibia's executive director of health, Ben Nangombe, could not be reached for comment.

South African traditional healers embrace tech
In December, many Africans return to their ancestral homes to reconnect with their families and traditions. In South Africa, that includes traditional healers. As Zaheer Cassim reports from Johannesburg, many are finding that a new app is helping to bring this age-old practice into the digital age.
