Risk factors of ocular morbidity among under-five years old children in Khartoum State- Sudan- 2020

BACKGROUND AND AIMS

Visual impairment in early childhood can significantly affect the development of visual, motor, and cognitive function and potentially lead to long-term adverse psychosocial consequences. This study aimed to identify the risk factors of ocular morbidity among under 5-year old children in Khartoum State, Sudan.

METHODS

A cross-sectional study was conducted in three tertiary eye care hospitals in Khartoum State, Sudan. The study included 391 children under the age of 5 years. The parent(s) were interviewed using a precoded, pretested, closed-ended questionnaire that included questions regarding socio-demographic profile and possible risk factors. Data were analyzed using Statistical Package for the Social Sciences (version 21.0). A P-value of less than .05 was regarded as significant.

RESULTS

There was a significant association between participants with diabetes mellitus and poor vision (P-value <.001). Two-thirds of participants (57%) with visual impairment had mothers, who reportedly attended antenatal care services regularly (P-value .001), revealing a significant statistical association. Maternal diseases, specifically diabetes, was identified as a risk factor for poor visual acuity in their offspring (P-value <.001). A significant relation was revealed between family history of eye disease and the degree of relationship to the affected participant (P-value <.001). There was an association between watching TV and current visual acuity (P-value <.001); as well as using mobile phones and current visual acuity (P-value <.001). Multilinear analysis revealed the stronger influence of TV watching rather than the use of mobile phones (P-value <.001).

CONCLUSIONS

Diabetes, diabetic mothers, a family history of ocular morbidity, watching television, and using mobile phones emerged as significant risk factors of ocular morbidity among children under the age of 5 years in this study. Many of these risk factors are either modifiable or controllable ocular morbidities among under-five children can be reduced with suitable interventions.

Barriers of access and utilization of reproductive health services by adolescents-Khartoum state-Sudan-2020: study protocol

BACKGROUND

Adolescence is widely defined as the time in life when the developing individual attains the skills and attributes necessary to become a productive and reproductive adult. Most adolescents are healthy, but there is still substantial premature death, illness, and injury among adolescents. Illnesses can hinder their ability to grow and develop to their full potential. Alcohol or tobacco use, lack of physical activity, unprotected sex and/or exposure to violence can jeopardize not only their current health, but also their health as adults or even health of their future children.

METHOD

Community and institutional-based cross sectional study will be conducted in Khartoum State the seven localities will be included. This state is the national capital of Sudan, which has an area of 22,122 km2. The sample size of participant is estimated using the population formula (n = N/1+ (n*d2)). The sample will be drawn using multistage cluster sampling. Also the concerned bodies involved in the delivery of reproductive health services for adolescents included in this study. Data will be collected using interviews with key informants and administered pre-coded, pretested closed ended questionnaire with community participants. Data will be managed and analyzed using Statistical Package for Social Sciences version 21. Analysis is mostly univariate descriptive and bi-variate with Chi Square & Fischer Exact test analysis to find associations between variables of interest.

DISCUSSION

The census of adolescents mounted to 25% of the population and thus it is important to care for such significant portion of the population to document their reproductive health problems and their access to health care services. The study is expected to generate base-line indicators about barriers of access to reproductive health services by adolescents that can be used for better planning, monitoring and evaluation of the delivered services. The research about barriers of access to reproductive health services by adolescents in Sudan is still limited and the information is scanty and scattered. Thus, it is necessary to conduct such study to enrich the current database.

Non-classical presentation of vitamin D deficiency: a case report

Background

Vitamin D is a fat-soluble vitamin; vitamin D is essential to sustain health and it protects against osteoporosis. It is crucial to the human body’s physiology in terms of muscular movement and neurological signal transmission, and to the immune system in defense against invading pathogens.

Case presentation

This was a case of a 26-year-old Sudanese woman who presented with a 2-year history of anosmia, recurrent nasal polyps, back pain, and chronic fatigue. She was diagnosed as having a case of vitamin D deficiency and responded well to treatment.

Conclusion

There is an association between vitamin D deficiency and recurrent allergic nasal conditions.

Nationwide cross-sectional survey of schistosomiasis and soil-transmitted helminthiasis in Sudan: study protocol

Background

Schistosomiasis and soil-transmitted helminthiasis (STHs) are target neglected tropical diseases (NTDs) of preventive chemotherapy, but the control and elimination of these diseases have been impeded due to resource constraints. Few reports have described study protocol to draw on when conducting a nationwide survey. We present a detailed methodological description of the integrated mapping of schistosomiasis and STHs on the basis of our experiences, hoping that this protocol can be applied to future surveys in similar settings. In addition to determining the ecological zones requiring mass drug administration interventions, we aim to provide precise estimates of the prevalence of these diseases.

Methods

A school–based cross-sectional design will be applied for the nationwide survey across Sudan. The survey is designed to cover all districts in every state. We have divided each district into 3 different ecological zones depending on proximity to bodies of water. We will employ a probability-proportional-to-size sampling method for schools and systematic sampling for student selection to provide adequate data regarding the prevalence for schistosomiasis and STHs in Sudan at the state level. A total of 108,660 students will be selected from 1811 schools across Sudan. After the survey is completed, 391 ecological zones will be mapped out. To carry out the survey, 655 staff members were recruited. The feces and urine samples are microscopically examined by the Kato-Katz method and the sediment smears for helminth eggs respectively. For quality control, a minimum of 10% of the slides will be rechecked by the federal supervisors in each state and also 5% of the smears are validated again within one day by independent supervisors.

Discussion

This nationwide mapping is expected to generate important epidemiological information and indicators about schistosomiasis and STHs that will be useful for monitoring and evaluating the control program. The mapping data will also be used for overviewing the status and policy formulation and updates to the control strategies. This paper, which describes a feasible and practical study protocol, is to be shared with the global health community, especially those who are planning to perform nationwide mapping of NTDs by feces or urine sampling.
