Objective: To assess the impact of a food-based intervention on blood pressure (BP) in free-living South African men and women aged 50-75 years, with drugtreated mild-to-moderate hypertension. Methods: A double-blind controlled trial was undertaken in eighty drug-treated mild-to-moderate hypertensive subjects randomised to an intervention (n 40) or control (n 40) arm. The intervention was 8-week provision of six food items with a modified cation content (salt replacement (SOLO TM ), bread, margarine, stock cubes, soup mix and a flavour enhancer) and 500 ml of maas (fermented milk)/d. The control diet provided the same quantities of the targeted foods but of standard commercial composition and 500 ml/d of artificially sweetened cooldrink. Findings: The intervention effect estimated as the contrast of the within-diet group changes in BP from baseline to post-intervention was a significant reduction of 6?2 mmHg (95 % CI 0?9, 11?4) for systolic BP. The largest intervention effect in 24 h BP was for wake systolic BP with a reduction of 5?1 mmHg (95 % CI 0?4, 9?9). For wake diastolic BP the reduction was 2?7 mmHg (95 % CI 20?2, 5?6). Conclusions: Modification of the cation content of a limited number of commonly consumed foods lowers BP by a clinically significant magnitude in treated South African hypertensive patients of low socio-economic status. The magnitude of BP reduction provides motivation for a public health strategy that could be adopted through lobbying of the food industry by consumer and health agencies.

“…Few studies have validated depression instruments for subSaharan cultures 10,11,[46][47][48][49][50][51][52] . The Patient Health Questionnaire-9 (PHQ-9) is the only validated instrument 11,46 that focuses on the nine diagnostic criteria for DSM-IV depressive disorders and is very brief 53 , an advantage in resource-constrained Kenyan clinics.…”

Validity/Reliability of PHQ-9 and PHQ-2 Depression Scales Among Adults Living with HIV/AIDS in Western Kenya

et al. 2008

BACKGROUND: Depression greatly burdens subSaharan Africa, especially populations living with HIV/ AIDS, for whom few validated depression scales exist. Patient Health Questionnaire-9 (PHQ-9), a brief dualpurpose instrument yielding DSM-IV diagnoses and severity, and PHQ-2, an ultra-brief screening tool, offer advantages in resource-constrained settings. OBJECTIVE:To assess the validity/reliability of PHQ-9 and PHQ-2. DESIGN: Observational, two occasions 7 days apart.PARTICIPANTS: A total of 347 patients attending psychosocial support groups.MEASUREMENTS: Demographics, PHQ-9, PHQ-2, general health perception rating and CD4 count. RESULTS:Rates for PHQ-9 DSM-IV major depressive disorder (MDD), other depressive disorder (ODD) and any depressive disorder were 13%, 21% and 34%. Depression was associated with female gender, but not CD4. Construct validity was supported by: (1) a strong association between PHQ-9 and general health rating, (2) a single major factor with loadings exceeding 0.50, (3) item-total correlations exceeding 0.37 and (4) a pattern of item means similar to US validation studies. Four focus groups indicated culturally relevant content validity and minor modifications to the PHQ-9 instructions. Coefficient alpha was 0.78. Test-retest reliability was acceptable: (1) intraclass correlation 0.59 for PHQ-9 total score, (2) kappas 0.24, 0.25 and 0.38 for PHQ-9 MDD, ODD and any depressive disorder and (3) weighted kappa 0.53 for PHQ-9 depression severity categories. PHQ-2 ≥3 demonstrated high sensitivity (85%) and specificity (95%) for diagnosing any PHQ-9 depressive disorder (AUC, 0.97), and 91% and 77%, respectively, for diagnosing PHQ-9 MDD (AUC, 0.91). Psychometrics were also good within four gender/age (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) subgroups.CONCLUSIONS: PHQ-9 and PHQ-2 appear valid/ reliable for assessing DSM-IV depressive disorders and depression severity among adults living with HIV/AIDS in western Kenya. INTRODUCTIONMore than 70% of all deaths attributable to HIV/AIDS are in sub-Saharan Africa, with approximately 6.1% of adults living with HIV in Kenya in 2005 1 . The social, economic and health impact of depression in sub-Saharan Africa is also great, where depression is associated with mortality 2-5 , work disability 4-7 , lower quality of life 5,[8][9][10][11][12] , risk of heart disease 13 and high-risk behaviors for contracting HIV infection 14 . With one exception 15 , the sparse literature on depression among individuals living with HIV/AIDS in sub-Saharan Africa has shown elevated rates of depression relative to community samples 3,8,10,[16][17][18][19][20][21][22][23][24][25] , consistent with western countries [26][27][28][29] . Thus, there is an urgency to incorporating mental health into HIV/ AIDS treatment programs in sub-Saharan Africa, including western Kenya [30][31][32][33][34][35] .Depression in sub-Saharan Africa presents in forms (culturespecific idioms, somatic, based on interpersonal relationships or spiritual in nature) that may o...

“…In the South African population, the EQ 5D has been used in measuring the HRQOL in non ICU populations (Jelsma et al 2004;Jelsma et al 2005;Louwagie et al 2007); no evidence of its use in the assessment of HRQOL of the South African ICU population could be found. The SF 36 has been used to assess HRQOL in some non ICU popu lations in South Africa (Benitha and Tikly 2007;O'Keefe and Wood 1996).…”
