RESUMO
BACKGROUND: Previous findings have been mixed regarding the relationship between maternal depressive symptoms and child cognitive development. The objective of this study was to systematically review relevant literature and to perform a meta-analysis. METHOD: Three electronic databases (PubMed, EMBASE, PsycINFO) were searched. Initial screening was conducted independently by two reviewers. Studies selected for detailed review were read in full and included based on a set of criteria. Data from selected studies were abstracted onto a standardized form. Meta-analysis using the inverse variance approach and random-effects models was conducted. RESULTS: The univariate analysis of 14 studies revealed that maternal depressive symptoms are related to lower cognitive scores among children aged ⩽56 months (Cohen's d = -0.25, 95% CI -0.39 to -0.12). The synthesis of studies controlling for confounding variables showed that the mean cognitive score for children 6-8 weeks post-partum whose mothers had high depressive symptoms during the first few weeks postpartum was approximately 4.2 units lower on the Mental Developmental Index (MDI) of the Bayley Scales of Infant and Toddler Development (BSID) compared with children with non-symptomatic mothers (BÌ = -4.17, 95% CI -8.01 to -0.32). CONCLUSIONS: The results indicated that maternal depressive symptoms are related to lower cognitive scores in early infancy, after adjusting for confounding factors. An integrated approach for supporting child cognitive development may include program efforts that promote maternal mental health in addition to family economic wellbeing, responsive caregiving, and child nutrition.

We explored the masculinity norms shaping transitions through puberty in rural and urban Tanzania and how these norms and their social-ecological context contribute to high-risk health behaviors. We conducted a qualitative case study of adolescent boys in and out of school in 2011 and 2012. Tanzania's social and economic development is reshaping the transition into young manhood. Adolescent boys are losing traditional mechanisms of pubertal guidance, and new meanings of manhood are arising from globalization. Traditional masculinity norms, including pressures to demonstrate virility and fertility, remain strong. Adolescent boys in modernizing Tanzania receive inadequate guidance on their burgeoning sexuality. Contradictory masculinity norms from family and society are shaping their sexual expectations, with implications for their engagement in unsafe sexual behaviors.

OBJECTIVES: To examine the socio-demographic and behavioral factors predictive of women's disclosure of an HIV-positive test result in Dar es Salaam, Tanzania. DESIGN: From April 1995 to May 2000, 1078 HIV-positive pregnant women participated in an ongoing randomized trial on micronutrients and HIV-1 vertical transmission and progression. Disclosure to a partner or to a female relative was assessed 2 months after post-test counseling and at 6 monthly follow-up visits. Socio-demographic, health, behavioral and psychological factors were measured at baseline and during follow-up. METHODS: Predictors of time to disclosure of HIV serostatus were determined using Cox proportional hazards regression models. RESULTS: Prevalence of disclosure to a partner ranged from 22% within 2 months to 40% after nearly 4 years. Women were less likely to disclose to their partners if they were cohabiting, had low wage employment, had previously disclosed to a female relative, or reported ever-use of a modern contraceptive method. Women reporting fewer than six lifetime sexual partners or knowing someone with HIV/AIDS were more likely to disclose to their partners. Disclosure to a female relative was predicted by knowing more than two individuals with HIV/AIDS, full economic dependency on their partner, high levels of social support, and prior attendance at a support group meeting. CONCLUSIONS: A substantial proportion of HIV-infected pregnant women never disclosed their result to a partner or a close female relative. Lack of disclosure may have limited their ability to engage in preventive behaviors or to obtain the necessary emotional support for coping with their serostatus or illness.

In an open clomipramine dose finding study, 33 depressed indigenous African outpatients were randomly assigned to two regimens of treatment with 125 mg and 75 mg oral medications daily. At the end of eight weeks of treatment, 16 patients (48.5 pc) were on the 75 mg regime, and 17 (54.8 pc) were on 125 mg. Analysis of depression scores on the Beck-Rafaelsen scale indicated improvements of depression in both regimes of equal magnitude. Analysis of variance showed no statistically significant difference on dose response between the two regimes. The higher doses, however, were associated with more drowsiness and tremulousness. It is suggested that Black African patients respond to tricyclic antidepressants in much lower doses than those recommended in Western textbooks. It is also apparent that side effects of tricyclic antidepressants, which have been implicated in non-compliance to medication, could be avoided without compromising treatment outcome.

PIP: Through use of a semi-structured interview schedule, the abortion decision-making process of 150 Dar es Salaam adolescents (mean age, 17.5 years) admitted with abortion-related complications was analyzed, with particular emphasis on the involvement of social networks. The male partner was the most frequent (47.3%) first confidant after pregnancy was suspected, followed by close relatives (35.1%) and girlfriends (14.0%). 62.0%, 41,7%, and 68.8% of these confidants, respectively, advised the teen to terminate the pregnancy; the remainder tended to express a lack of interest in her predicament. The link to an abortionist was provided by mothers, sisters, or aunts in 33% of cases, by the male partner in 32% of cases, and by girlfriends in another 24%. Male partners were more likely to provide funds for the abortion--especially if the woman was a student--than to help her access an abortionist. When abortion-related complications created a need for hospitalization, only 18% of male partners provided assistance; this burden fell upon female relatives. It is postulated that male involvement, beyond the provision of money, is inhibited by the potential legal and social consequences of illegal abortion in Tanzania.^ieng

In this study, the effects on young adolescent sexual risk behaviour of teacher-led school HIV prevention programmes were examined in two sites in South Africa (Cape Town and Mankweng) and one site in Tanzania (Dar es Salaam). In Cape Town, Dar es Salaam and Mankweng, 26, 24 and 30 schools, respectively, were randomly allocated to intervention or comparison groups. Primary outcomes were delayed sexual debut and condom use among adolescents aged 12-14 years (grade 8 in South Africa and grades 5 and 6 in Tanzania). In total, 5352, 4197 and 2590 students participated at baseline in 2004 in Cape Town, Dar es Salaam and Mankweng, respectively, and 73% (n = 3926), 88% (n = 3693) and 83% (n = 2142) were retained 12-15 months later. At baseline, 13% (n = 224), 5% (n = 100) and 17% (n = 164) had had their sexual debut, and 44% (n = 122), 20% (n = 17) and 37% (n = 57) of these used a condom at last sex, respectively. In Dar es Salaam, students in the intervention were less likely to have their sexual debut during the study (OR 0.65, 95% CI 0.48-0.87). In Cape Town and Mankweng, the intervention had no impact. The current interventions were effective at delaying sexual debut in Dar es Salaam but not in South Africa, where they need to be supplemented with programmes to change the environment in which adolescents make decisions about sexual behaviour.
RESUMO
Several studies show depression is common during pregnancy. However, there is limited information in Tanzania on the magnitude of perceived distress during pregnancy and meanings ascribed to such distress. A descriptive survey collected data using unstructured interviews from 12 traditional practitioners and 10 peri-urban women with previous pregnancy related mental health concerns identified using a depression vignette. The objectives were to describe the sources and characteristics of distress during pregnancy, and idioms of distress that could inform cultural adaptation of depression screening tools. Narrative analysis showed an emergent category of "problematic pregnancies" framed women's recollections of prolonged periods of sadness. This experience was qualified using various idioms of distress that were differentially emphasized depending on informant's perceived causes of health concern. The idiom kusononeka was consistently used to describe extreme sadness across causal categories and clustered with at least two typical features of major depression. This suggested existence of a construct with similarities to biomedical criteria for depression. "Thinking too much" emerged as a distinctive expression associated with prolonged sadness. Distinctive expressions of social functioning impairments were identified that can inform depression severity assessments. In conclusion, contextual inquiry into experiences of psychological distress showed distinct local idioms that clustered in patterns similar to symptoms of biomedical depressive episodes. Further studies to assess the utility of local idioms of distress and distress related functional impairment in depression assessment tools are warranted.

Depression during pregnancy may negatively influence social functioning, birth outcomes and postnatal mental health. A cross-sectional analysis of the baseline survey of a prospective study was undertaken with an objective of determining the prevalence and socio-demographic factors associated with depressive morbidity during pregnancy in a Tanzanian peri-urban setting. Seven hundred and eighty seven second to third trimester pregnant women were recruited at booking for antenatal care at two primary health care clinics. Prenatal structured interviews assessed socio-economic, quality of partner relationships and selected physical health measures. Depressive symptoms were measured at recruitment and three and eight months postpartum using the Kiswahili version of the Hopkins Symptom Checklist. Completed antenatal measures available for 76.2% participants, showed a 39.5% prevalence of depression. Having a previous depressive episode (OR 4.35, P<0.01), low (OR 2.18, P<0.01) or moderate (OR 1.86, P=0.04) satisfaction with ability to access basic needs, conflicts with the current partner (OR 1.89, P<0.01), or booking earlier for antenatal care (OR 1.87, P=0.02) were independent predictors of antenatal depression in the logistic regression model; together explaining 21% of variance in depression scores. Attenuation of strength of multivariate associations suggests confounding between the independent risk factors and socio-demographic and economic measures. In conclusion, clinically significant depressive symptoms are common in mid and late trimester antenatal clinic attendees. Interventions for early recognition of depression should target women with a history of previous depressive episodes or low satisfaction with ability to access basic needs, conflict in partner relationships and relatively earlier booking for antenatal care. Findings support a recommendation that antenatal services consider integrating screening for depression in routine antenatal care.

OBJECTIVES: The primary objective of this study was to examine the effect of vitamin supplementation on health-related quality of life and the risk of elevated depressive symptoms comparable to major depressive disorder (MDD) in HIV-positive pregnant women in Dar es Salaam, Tanzania. METHODS: From April 1995 to July 1997, 1078 HIV-positive pregnant women were enrolled in a randomized controlled trial. We examined the effects of vitamin supplementation on quality of life and the risk of elevated depressive symptoms, assessed longitudinally every 6-12 months. RESULTS: A substantial prevalence of elevated depressive symptoms (42%) was observed in HIV-positive pregnant women. Multivitamin supplementation (B-complex, C and E) demonstrated a protective effect on depression [relative risk (RR)=0.78; P=0.005] and quality of life [RR=0.72 for social functioning (P=0.001) and vitality (P=0.0001); RR=0.70 for role-physical (P=0.002)]; however, vitamin A showed no effect on these outcomes. CONCLUSIONS: Multivitamin supplementation (B-complex, C and E) resulted in a reduction in risk of elevated depressive symptoms comparable to MDD and improvement in quality of life in HIV-positive pregnant women in Tanzania.

The family in the United Republic of Tanzania has traditionally been a paramount institution invested with important functions of socialization. It provided spiritual guidance, emotional and social support systems, security and education, and defined the moral and ethical system in which the community was intricately bound together. The institution is weakening under the impact of modernization at a pace that far exceeds the pace at which newer institutions are emerging to assume those responsibilities. Drug abuse is becoming an unwelcome guest under those circumstances. It is proposed that active measures should be taken at the community and national policy level to strengthen and employ the family for the purpose of promoting a drug-free lifestyle.

An improved teaching package is described which aims to help general practice trainees manage somatized presentations of psychological distress. The package comprises a training videotape in which a reattribution model is demonstrated, with material for role-play of new skills and small-group video feedback of consultations. Eighteen general practice trainees attending an 8-week course in psychiatry participated fully in the somatization management teaching programme. The teaching package was evaluated by blind rating of general interview skills and model specific skills demonstrated by trainees during 10 to 15-minute clinical interviews with professional role-players. Ratings were made on pre-training and post-training videotaped interviews. A significant improvement was demonstrated in general interview skills. Improvements were also noted in specific reattribution skills post-training. The evaluation revealed that skills in the model can be effectively learned, and that improvements in the package have resulted in its improved efficacy.

PIP: Focusing on increased vulnerability to HIV infection, this article examines some of the contexts within which these risk-taking behaviors occur and illustrates that the risk of contracting the disease is just one of the many risks with which Tanzanian youths are confronted. The sexual and substance use behaviors, and the relationship between such behaviors and economic factors, are discussed. Where evidences exist, attempts are made to compare the prevalence of these behaviors among male and female youths, as well as urban and rural youths. The extent to which males and females engage in risk-taking behaviors is unknown; however, studies show that, depending on age and gender, between 17% and 61% of youths are sexually active. Rates in HIV transmission vary by gender and by whether the youths are rural or urban inhabitants. Factors like adverse socioeconomic conditions, unemployment, lack of parental guidance and supervision, and culture all influence sexual risk-taking behaviors among youths. Meanwhile, increasing use of drugs and alcohol among the young population has been closely linked to increased vulnerability to unprotected sexual intercourse. Again, survival needs play a major role in sustaining risk behaviors. The paper concludes by outlining policy implications of youth risk behaviors, taking into account a multisectoral approach in dealing with the problem.^ieng

OBJECTIVE: To validate the Hopkins Symptom Checklist-25 (HSCL-25) for use as a depression screen amongst human immuno-deficiency virus (HIV) positive pregnant women. METHOD: Amongst 903 (mean age 24.8 years) HIV-positive pregnant women, a two-phased design included measures for health-related quality of life, perceived social support, and the HSCL-25 screen for depressive (HSCL-15 subscale) and anxiety symptoms. The Structured Clinical Interview for DSM-IV (SCID) was independently administered on a stratified random subsample. RESULTS: Internal consistency of the HSCL-25 (alpha 0.93) and HSCL-15 (alpha 0.9) was adequate, with expected findings demonstrated in discriminant validity analysis. A depression-anxiety construct explained nearly 40% of the variance. Eight individual HSCL-25 items demonstrated an area under the curve (AUC) greater than 0.6 for DSM-IV major depression and the HSCL-25 and HSCL-revised had an optimal depression cut-off score of 1.06 and 1.03 for the HSCL-15. CONCLUSION: The HSCL-25 demonstrated utility as a screen for depression; its inability to gauge severity of symptoms in this cultural context is discussed.

OBJECTIVE: To examine the association between maternal HIV infection and pregnancy outcomes controlling for potential confounding factors among a cohort of HIV-uninfected and HIV-infected pregnant women in Dar es Salaam, Tanzania. DESIGN: Prospective cohort study. METHODS: A cohort of 1,078 HIV-infected and 502 HIV-uninfected pregnant women between 12 and 27 weeks of gestation were enrolled and followed up until delivery. Multiple regression models were used to compare the risk of adverse pregnancy outcomes among HIV-uninfected women with those among HIV-infected women overall, and separately among asymptomatic or symptomatic HIV-infected women. RESULTS: No significant differences between HIV-uninfected women and HIV-infected women were observed in risks of fetal loss or low birthweight or in the weight, head circumference and gestational age of infants at birth. HIV-infected women were more likely to have severe immature infants (<34 weeks) than HIV-uninfected women (multivariate RR 1.54 [95% CI 0.90-2.48]; P= 0.05). There was a significantly higher risk of low birthweight (RR 2.29, 95% CI 1.34-3.92; P = 0.03) and prematurity (<37 weeks) (RR 1.93, 95% CI 1.35-2.77; P = 0.0003) among symptomatic HIV-infected women when compared with HIV-uninfected women. CONCLUSION: HIV-infected women, particularly those whoare symptomatic, are at a higher risk of adverse pregnancy outcomes.

OBJECTIVES: The study was carried out to investigate the distribution of cytochrome P450 2D6 (CYP2D6) and CYP2C19 genotype frequencies in three African populations and to compare these frequencies between healthy individuals and psychiatric patients. METHODS: Three hundred and eighty-four subjects from South Africa (Venda), Tanzania, and Zimbabwe who consented to the study were genotyped for CYP2D6 (CYP2D6*1, *2, *3, *4, *5, and *17) and CYP2C19 (CYP2C19*1, *2, and *3) by PCR-RFLP (polymerase chain reaction restriction fragment length polymorphism) techniques. RESULTS: The genotypes for CYP2D6 predicted a poor metabolizer frequency of 2.3% (2/88) in Tanzanian psychiatric patients, 1.9% (2/106) in Tanzanian healthy controls and 2.6% (2/76) in the South African Venda. The low-activity CYP2D6*17 allele frequency was higher in psychiatric patients (30%, 53/176) than in healthy individuals (20%, 43/212) in Tanzanians. The frequencies for CYP2C19*2 genotypes were predictive of a low prevalence of poor metabolizers (PMs). The CYP2C19*3 allele was absent in the three populations studied. There was no difference in CYP2D6 or CYP2C19 PM genotype frequencies between psychiatric patients and healthy subjects. CONCLUSION: The genotype results predict a low prevalence of people with deficient CYP2D6 and CYP2C19 activity among linguistically (Bantu) related populations of East and Southern Africa. The high frequency of the low-activity CYP2D6*17 allele predicts that the Bantu people have a reduced capacity to metabolise drugs that are CYP2D6 substrates.
