1 Washington D.C., USA, July 2012www.aids2012.org The critical role of social cohesion on uptake of HIV testing and ART in Zambia Swiss Tropical and Public Health Institute University of Zambia

2 Washington D.C., USA, July 2012www.aids2012.org BACKGROUND >14% HIV prevalence among adults  Despite free access  Despite free access to HIV related services: only 35% of women and 20% of men have been tested and received their results; up to one third treated with ARVs dropped out of the programs.  Reasons? health system constraints, poverty, gender inequality, stigma, beliefs… dynamics of decision-making ?

3 Washington D.C., USA, July 2012www.aids2012.org METHOD Cross sectional study (part of a larger mixed-method study) Ethnographic study Systematic review QUESTIONNAIRE SD, SES, FS, K&B, STG, Health risk behav., Social relationships SURVEY Random community sample Nested Facility-based sample

4 Washington D.C., USA, July 2012www.aids2012.org STUDY POPULATION  Four sites urban : LUSAKA and MAZABUKA rural: MBEZA and CHIVUNA  Inclusion criteria being over the age of 18 living in the area for at least six months  Exclusion criteria having participated in the community-based survey

5 Washington D.C., USA, July 2012www.aids2012.org STATISTICAL ANALYSIS  Scales Mokken Scale analysis for polytomous items, implemented in STATA modules msp and Loevh (Non-parametric IRT)  Estimated effects  Estimated effects : Logistic regression analysis 3 steps: univariable – focal models – multivariable Retention in model if P-value<0.02

9 Washington D.C., USA, July 2012www.aids2012.org Risk of not testing Explanatory variablesAOR95%CIP-value Urban2.45* Female0.65* Wealth (poor)1.14* Married0.44* Widow/divorced Social capital Do not attend religious services1.33* Do not participate in any community activity 1.31* Social cohesion Problems in neighbour relationships * * significant, p=0,005 1 combines "people in this neighbourhood don't get along with each other; People around here are willing to help their neighbours".

10 Washington D.C., USA, July 2012www.aids2012.org Risk of not initiating ART * significant, p=0, combines "in times of crisis I can turn to my spouse/partner for support; My spouse/partner and I get along well together; I trust my partner; Feel supported by people of my household". 2 combines "if someone in the household misuses money it is acceptable to beat him/her; In my household if a wife comes home late without the permission of the husband she will be beaten". 3 combines "traditional medicine better relieves symptoms compared to ARV’s; traditional medicine cures; is easier to apply; easier to access; HIV may be caused by witchcraft; ARV’s are against black people; African people used as guinea pigs". Explanatory variablesAOR95%CIP-value Widow/divorced Social cohesion Problems in neighbour relationships Problems in family relationships * Tolerance to domestic violence * Beliefs in efficacy of traditional medicine *

11 Washington D.C., USA, July 2012www.aids2012.org Conclusions Less cohesive communities put individuals at higher risk of non-accessing HIV services. For the initiation of ART, family cohesion and trust in traditional medicines play a bigger role. Not only enacted violence adds to the burden of HIV but its tolerance within families also jeopardizes access to treatment. LIMITATIONS - design does not allow establishing a temporal relationship; - self reported rates (recall bias).

12 Washington D.C., USA, July 2012www.aids2012.org Recommendations  Interventions should target community and family in addition to individual and/or couple.  Promote community participation and collective action. (Acknowledge traditional relationship systems)  For future research longitudinal studies need to clarify the causal links between social cohesion and HIV testing and to confirm replicability in other contexts.
