Immunisation-related knowledge, attitudes and practices of mothers in Kinshasa, Democratic Republic of the Congo

Background: In the Democratic Republic of Congo, it was reported in 1995 that the routine coverage for BCG was as low as 47%, and that it was 27% for DPT3, 28% for OPV3 and 39% for measles vaccine. The trend also was declining unevenly. This study aimed to determine the reasons for such low coverage, examining the socio-demographic characteristics of mothers and health system factors such as health services barriers. It further sought to assess the knowledge, attitudes and practices of mothers associated with routine immunisation. Methods: In 1999, a cross-sectional household survey applied a systematic sampling technique in a sample of eight out of the 22 health zones that then served the population of Kinshasa. These were dichotomised into low- and high-coverage health zones, based on BCG immunisation coverage. Mothers of children aged from zero to four years were the respondents to a standardised questionnaire. Results: A total of 1 613 children aged zero to four years participated in the study. Awareness of immunisation and its importance in protecting a child against diseases was universal, although most mothers could not tell exactly against which diseases. Mothers had positive attitudes towards immunisation (98%). Coverage based on the immunisation card, however, was as low as 37%, indicating a discrepancy between the high level of knowledge and positive attitudes, with the observed low immunisation coverage. The father's education and the mother's experience of an EPI-targeted disease in the family emerged as significant predictors of complete immunisation of the child. The father's involvement and the mother's ability to cite signs of severity of EPI diseases were associated with the child's vaccination status in the high-coverage health zone. The mother's vaccine-related knowledge was a predictor of immunisation status only in the low-coverage zone. Conclusion: Different factors determine the complete vaccination status, depending on whether the child lives in a zone with low or high routine EPI coverage. For example, the father's involvement is associated with the child's vaccination status in the high- coverage zone, but not in the low-coverage zone. Programmes and policy makers should take these factors into account when designing strategies to increase immunisation coverage. South African Family Practice Vol. 50 (2) 2008: pp. 61-61

Obesity and diabetes mellitus association in rural community of Katana, South Kivu, in Eastern Democratic Republic of Congo : Bukavu Observ Cohort study results

Background: Factual data exploring the relationship between obesity and diabetes mellitus prevalence from rural areas of sub-Saharan Africa remain scattered and are unreliable. To address this scarceness, this work reports population study data describing the relationship between the obesity and the diabetes mellitus in the general population of the rural area of Katana (South Kivu in the Democratic Republic of the Congo). Methods: A cohort of three thousand, nine hundred, and sixty-two (3962) adults (>15 years old) were followed between 2012 and 2015 (or 4105 person-years during the observation period), and data were collected using the locally adjusted World Health Organization's (WHO) STEPwise approach to Surveillance (STEPS) methodology. The hazard ratio for progression of obesity was calculated. The association between diabetes mellitus and obesity was analyzed with logistic regression. Results: The diabetes mellitus prevalence was 2.8 % versus 3.5 % for obese participants and 7.2 % for those with metabolic syndrome, respectively. Within the diabetes group, 26.9 % had above-normal waist circumference and only 9.8 % were obese. During the median follow-up period of 2 years, the incidence of obesity was 535/100,000 person-years. During the follow-up, the prevalence of abdominal obesity significantly increased by 23 % (p < 0.0001), whereas the increased prevalence of general obesity (7.8 %) was not significant (p = 0.53). Finally, diabetes mellitus was independently associated with age, waist circumference, and blood pressure but not body mass index. Conclusion: This study confirms an association between diabetes mellitus and abdominal obesity but not with general obesity. On the other hand, the rapid increase in abdominal obesity prevalence in this rural area population within the follow-up period calls for the urgent promoting of preventive lifestyle measures

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI 2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining https://researchonline.ljmu.ac.uk/images/research_banner_face_lab_290.jpgunderweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesity

Seizures associated with fever and psychomotor development in primary health care in Kinshasa

peer reviewedUne étude prospective menée pendant 3 mois dans 2 centres des soins de santé primaires à Kinshasa, a permis de décrire les caractéristiques sémiologiques des Convulsions Fébriles (CF) présentées par 148 patients, âgés de 5 à 71 mois. Les CF ont été décrites en fonction de leur distribution, leur durée et leur répétition éventuelle. Les caractères latéralisés, prolongés et répétitifs étaient considérés comme des facteurs de gravité. Le Quotient de Développement psychomoteur (QDP) des patients a été évalué sur base de l’échelle de Gensini et Gavito, reprenant les domaines de la motricité, de la communication, et de l’adaptation. Le QDP était bas chez 6,7% des patients. 5% avaient un retard dans le domaine de la motricité, 3,4% dans le domaine de la communication, et 2,7% dans celui de l’adaptation. Nous n’avons pas noté de lien significatif entre le QDP global, et les facteurs de gravité des CF. Toutefois, tous les enfants ayant un retard dans le domaine de la motricité, avaient présenté des convulsions répétées avant leur admission: (p=0,02 [OR=1,096 (IC 95%) : 1,060 -1,128)]. La motricité était l’élément le plus significativement atteint chez les malades ayant présenté les CF. Cette observation mérite d’être validée par des études castémoins, incluant un plus grand nombre de sujets.Summary A prospective and descriptive study including 148 children (age: 5-71 months) presenting with febrile seizures (FS) at two Primary Health Care centres in Kinshasa, was conducted over a period of 3 months. Type of seizure (genaralized or focal), its duration, and its characteristic (recurrent or not), were documented, to assess the severity of the disorder. The Psychomotor Development (PMD) of each patient was evaluated, using the Gensini and Gavito scale and then the Psychomotor Development Quotient (PDQ) calculated, according to the motor, communication, and social domains. Main results were: a reduction in PDQ (6.7%), motor delay (5%), communication delay (3.4%), and social delay (2.7%), based on this scale. No significant link was found between global PDQ reduction and markers of FS severity. However, recurrent seizures seemed strongly associated to delayed motor development (p=0.02 [OR=1.096, CI: 1.060-1.128]). These findings suggest that the motor domain could be more affected in children presenting FS, especially those with recurrent seizures. This link needs to be clearly established through larger case-control studies

Knowledge Of Hiv, Sexua Behagior And Correlates Of Risky Sex Among Street Children In Kinshasa, Democratic Republic Of Congo

Context: Homeless children are at risk of getting many diseases, including sexually transmitted infections (STI). The number of street children is on the rise in the Democratic Republic of Congo (DRC), while very little is known about their health problems. Objectives: To determine knowledge of HIV (transmission and prevention means), sexual activity, exposure to HIV-prevention services, and to identify correlates of risky sexual behaviour (not having used a condom at first or last sexual encounter and/or having multiple sexual partners over a 12-month period) among street children in Kinshasa. Results: At the time of the survey, most participants (85.8%, 95% CI = 83.5-88.1) were sexually experienced and 55.8% had their first sexual intercourse when they were already living on the streets. The median age at first sexual activity was 14.3 years for males and 13.5 years for females. Compared to males (median number of sexual partners = 1), females tended to be more involved with multiple sexual partners (median = 12). Condoms were used less at the fist sexual encounter (20.2%; 95% CI =17.3-23.1) and the pattern of condom use depended on the type of sexual partners (61.1% at last sexual encounter with a paid/paying partner and 23.1% at last sexual encounter with a non-paid/non-paying partner). In males, sleeping in a NGO-provided night shelter (OR= 0.47; 95% CI = 0.27–0.79), and having had the first sexual intercourse while living on the streets (OR = 0.55; 95% CI = 0.35-0.88) were protective of risky sexual behaviour, while a history of drug use (OR = 3.00; 95% CI = 1.46–6.18), and being aged 20 to 24 years (OR = 1.59; 95% 1.00–2.55) increased the likelihood of displaying risky sexual behaviour. In females, not knowing where to get a condom (OR = 0.04; 95% CI = 0.005–0.29), having started sexual activity when living on the streets (OR = 0.10; 95% CI = 0.01–0.73) and not having an income-generating activity (OR = 0.09; 95% CI = 0.01–0.44) were protective of risky sexual behaviour. Conclusion: Street children need to be regarded as a high-risk group for acquiring HIV. The potential benefit of providing homeless youth with night-shelters should be explored more since this could be an opportunity to integrate risk-reduction programmes that take into account all problematic behaviors such as risky sexual behaviour and drug use.
