- W2024151921 abstract "In this study, Central composite face-centered and Box–Behnken designs were employed to study the main and interaction effects of demographic characteristics on the risk of HIV in South Africa. The demographic characteristics studied for each pregnant mother attending an antenatal clinic in South Africa were mother’s age, partner’s age (father’s age), mother’s level of education, and parity. The central composite face-centered and Box–Behnken designs showed that the risk of acquiring HIV status for an antenatal clinic attendee was highly sensitive to changes in pregnant woman’s age and her educational level, using the 2007 South African annual antenatal HIV and syphilis seroprevalence data. Individually the age of the pregnant woman’s partner and her parity had no significant effect on the HIV risk. However, the latter two demographic characteristics exhibited significant effects on the HIV risk in two-way interactions with other demographic characteristics. Using HIV as the optimization objective, the following summary statistics were obtained: R 2 = 0.99 (Central composite face-centered design) and R 2 = 0.99 (Box–Behnken design). The two-factor interactions model F values for the central composite and Box–Behnken designs were 7.99 and 88.29, respectively. These F values for the 2-factor interactions were significant with only a 0.12 and 0.01 % chance that these model values were a result of noise. Adeq precision values of 8.84 and 31.33 for the central composite face-centered and Box–Behnken, respectively, suggested that these two-factor interactions models could be used to navigate the design spaces. Finally, the main effects and interactions plots illustrated that the HIV risk increased with the age of the pregnant woman." @default.
