Smoking among secondary school students in Zimbabwe

Leave a comment

Nearly one-third of secondary school students in Harare, Zimbabwe, have ever smoked, a study reports. The percentage of boys who have ever smoked (37.8 percent) was significantly much higher than among girls (18.5 percent).

The study found that smoking among these students was linked to having friends or family that smoke, getting involved in physical fights, alcohol use, marijuana use and having had sexual intercourse.

HIV decline in Zimbabwe due to reductions in risky sex

Leave a comment

A study has found convincing evidence of an HIV decline accelerated by changes in sexual behavior in Zimbabwe, an African country ravaged by HIV/AIDS.

HIV prevalence fell in Zimbabwe over the past decade—from 29.3 percent in 1997 to 15.6 percent in 2007. Reductions in the proportions of men and women with non-regular sexual partners and sustained high levels of condom use during this period likely contributed to the decline in HIV prevalence.

Estimates indicated that HIV incidence may have peaked in the early 1990s and fallen during the 1990s; and multiple local and national surveys showed substantial rises in AIDS-related deaths during the 1990s leveling off after 2000.

However, AIDS-related deaths in Zimbabwe remained at crisis levels in the mid-2000s, according to the study.
