Factors associated with provision of physical activity in primary schools in Makindye Division in Kampala, Uganda: a cross-sectional study.

BACKGROUND: Globally, school-going children spend most of their days at school, sitting in lessons and unable to achieve the daily WHO recommendations for Physical Activity (PA) of at least 60 minutes per day. Limited studies have assessed the opportunities schools provide for PA to help the children achieve their daily recommended PA. We determined the level of and the factors associated with PA offered in primary schools in Makindye Division in Kampala during the school term. METHODS: This cross-sectional study was conducted in 36 selected government and private primary schools in Makindye Division, Kampala. PA was defined as the amount of time in minutes available for PA as per WHO recommendations - sufficient (60 minutes or more of PA) or insufficient (less than 60 minutes of PA) and assessed for any factors associated with provision of time for PA in schools. Data were collected by interview administered questionnaires and analysed descriptively. Factors associated with PA were assessed using a logistic regression model. RESULTS: Of the 36 schools, 3 were government and 33 were private schools. The proportion of schools offering sufficient time for PA among Primary schools in the Makindye Division was (8/36) 22%. The average time for PA for all schools per week was 197 minutes (SD 70.7). Sufficient PA was associated with the provision of PE lessons after a break or after lunch (p-value 0.038). Sufficient PA was more likely in schools that offered volleyball (OR 8.69), had space in the school for PA (OR 13.27), provided athletics (OR 2.26) and whose fees were Ushs 700,000 (USD 187) or more (OR 1.30). CONCLUSIONS: Only 22% of sampled schools offered sufficient time for PA among Primary schools in Kampala per WHO guidelines. Provision of sufficient time for PA was associated with PE scheduled either after break or lunch. Sufficient PA was more likely with schools that had space for PA, schools which offered volleyball and athletics, and whose fees were 700,000/= or more. Schools should consider scheduling PE lessons after break or after lunch to increase the likelihood of meeting the targeted time for PA. Primary schools need to be supported to establish facilities and to increase diversity in available activities to ensure children achieve their recommended PA.

The effectiveness of adolescent-specific prenatal interventions on improving attendance and reducing harm during and after birth: a systematic review.

BACKGROUND: Adolescent pregnancy has been associated with poor pregnancy outcomes including pre-term birth (PTB), low birth weight (LBW) and perinatal death. OBJECTIVE: To systematically review the effect of adolescent-specific interventions on reducing PTB, LBW, and perinatal death and increasing prenatal care attendance. SEARCH STRATEGY: Possible studies for inclusion were identified by a comprehensive search of OvidSP MEDLINE (limits: humans, 1990-present), EMBASE (limits: humans, 1990-2015), Popline and Global Health Database from the World Health Organisation (WHO) and PubMed International scientific databases, and references of identified articles were searched from 1990 to present. SELECTION CRITERIA: All types of controlled studies of prenatal interventions were exclusive to adolescents and at least one of the outcomes of interest. DATA COLLECTION AND ANALYSIS: Investigators identified relevant studies and entered the data in a pro forma. Data were summarised as forest plots and narrative synthesis. MAIN RESULTS: Twenty-two studies (three randomised controlled trials (RCTs), four prospective cohort studies, nine retrospective cohort studies, five case controls and one natural experiment) were included with all but one study being carried out in higher-income countries. Seven of the 16 studies reporting on PTB found a statistically significant reduction in PTB rates between adolescent-specific prenatal care (intervention) and non-age specific prenatal care odds ratio (OR) and 95% confidence intervals (CIs) ranged from OR: 0.15 (95% CI: 0.03-0.83) to OR: 0.59 (95% CI: 0.45-0.78). Nine of the 12 studies reported statistically significant higher mean prenatal attendance rates among the intervention group compared to controls (ranging from a mean number of visits of 14.3 vs. 10.7 p<0.001 to 10.8 vs. 7.6 visits p<0.001). The type and construct of the interventions, their implementation and local population differed sufficiently that a statistical synthesis was deemed inappropriate. CONCLUSION: There is some evidence that adolescent-specific programs can increase prenatal attendance and reduce the risk of PTB and low birth rate but their effect on perinatal death is uncertain. There is a distinct lack of evidence of the effectiveness of these interventions for adolescents living in low-middle income countries, despite having the majority of adolescent pregnancies, and associated risk of harm. No high-quality intervention studies were identified. Robust, cluster-based RCTs are an urgent necessity to quantify the impact of these interventions and to identify factors contributing to their success.

Foetal haemoglobin and disease severity in sickle cell anaemia patients in Kampala, Uganda.

BACKGROUND: Sickle cell anaemia (SCA) is a major chronic health problem in Uganda. In patients with SCA, the level of foetal haemoglobin (HbF) has been found to be important in influencing the clinical course of the disease. Thus populations with high levels of HbF like those in Saudi Arabia have been described as having a milder clinical course with fewer complications as compared to populations with lower levels. Disease modifying drugs can increase the Hb F levels and modify the presentation of SCA. METHODS: This was a cross sectional study in which we determined foetal haemoglobin levels and examined the relationship between HbF levels and disease severity in SCA patients in Mulago Hospital, Kampala, Uganda. We consecutively enrolled 216 children aged 1 year to 18 years with SCA attending the Sickle Cell Clinic at Mulago Hospital whose guardians had given consent. The history included age at onset of initial symptoms and diagnosis, number of hospitalisations and blood transfusions and other complications of SCA (cardiovascular accidents, avascular hip necrosis and priapism). A detailed physical examination was performed to assess the current state and help describe the disease severity for each patient. Blood samples were drawn for HbF levels. HbF levels ≥10% was defined as high. RESULTS: Of the 216 children, (80) 37% had HbF levels ≥10%. Significant correlations were observed between HbF level and several clinical parameters independent of age including age at diagnosis (p value 0.013), number of hospitalisations (p value 0.024) and transfusions (p value 0.018) since birth. CONCLUSION: A third of the children with SCA attending the Sickle cell clinic in Mulago Hospital have high HbF levels. Higher HbF level is associated with later onset of symptoms and presentation, and less severe disease characterised by fewer hospitalisations and blood transfusions. We suggest HbF levels should be determined at initial contact for patients with SCA to guide counselling and identify those who may need closer follow up and consideration for disease modifying drugs.
