Effectiveness of a Community-Based Intervention Program to Reduce Hypertension Prevalence Among Adults: Results of a Quasiexperimental Study With Control Group in the Region of Sousse, Tunisia

Abstract

This study showed the feasibility and effectiveness of a community-based intervention to reduce the prevalence of hypertension in the context of a developing country.

Health promotion interventions for the control of hypertension in Africa, a systematic scoping review from 2011 to 2021

“…The study designs adopted were survey [ 21 , 25 ], quasi-experimental [ 30 – 32 ], Cohort [ 22 , 24 , 25 ], mixed methods [ 26 ], randomised control [ 20 ], and exploratory uncontrolled pre–post intervention [ 23 ] as shown in Table 1 . The studies were conducted in the Faculty of Pharmacy at Rhodes University [ 21 ], the Gugulethu township of Cape Town [ 26 ], Khayelitsha [ 24 ] all in South Africa [ 22 , 25 ], Sousse in Tunisia [ 30 ], Afon and Ajasse Ipo districts in Kwara State in Nigeria [ 31 ], three community pharmacies in the Ashanti Region of Ghana [ 23 ], and the slums of Korogocho and Viwandani in Nairobi [ 30 ]. The target participants for the health promotion interventions had a minimum age of eleven [ 21 ] and a maximum of sixty-five years [ 30 ] and included both sexes.…”

The target participants for the health promotion interventions had a minimum age of eleven [ 21 ] and a maximum of sixty-five years [ 30 ] and included both sexes. The sampling methods adopted were the convenience [ 21 , 23 , 24 , 26 , 30 ], stratified convenience [ 25 ], random [ 30 ], stratified 2-degree random probability by geographic areas [ 31 ], and the Markov model used as a tool for sampling with the focus on age variability of cardiovascular diseases [ 22 ].…”

The study duration for each intervention study ranged from a minimum of a day health education programme [ 21 ] to a maximum of 36 months health promotion for behaviour change [ 30 ]. The other studies were 3months [ 25 ], 4 months [ 20 , 26 ], 5 months [ 23 ], 9 to 10 months [ 25 ], 12 months [ 22 ], 18months [ 32 ] and 24 months [ 24 , 31 ] health promotion interventions.…”

“…Health promotion interventions were noted to have a positive impact on the prevalence of hypertension [ 30 – 32 ] as shown in key findings in Table 2 . The health promotion interventions led to a remarkable decrease in the prevalence of hypertension in the intervention compared to the control groups [ 30 , 31 ]. It was reported that the prevalence of hypertension decreased in the treatment group globally from 37.3% to 33.7% [ 30 ].…”
