Insights
Growth is severely impaired in children with sickle cell disease (SCD) in Yemen, with many exhibiting low weight and height. Nutritional support and growth monitoring are crucial for comprehensive SCD care.
Area of Science:
- Pediatrics
- Hematology
- Public Health
Background:
- Physical growth is frequently impaired in children with sickle cell disease (SCD).
- The prevalence and severity of growth impairment in SCD vary geographically.
- Underlying factors contributing to suboptimal growth in SCD remain poorly understood.
Purpose of the Study:
- To evaluate the growth status of children and adolescents with SCD in Yemen.
- To utilize new World Health Organization (WHO) reference values for growth assessment.
- To examine correlations between growth indicators, disease severity, and hematological/biochemical parameters.
Main Methods:
- A cross-sectional study was conducted involving children under 16 years with SCD.
- Anthropometric measurements including weight, height, mid-upper-arm circumference (MUAC), and body mass index (BMI) were collected.
- Disease severity was quantified using a severity index (SI) score.
Main Results:
- 45% of 102 children had low weight-for-age, 54% low height-for-age, and 35% low BMI-for-age Z-scores (<-2 SD).
- Low height-for-age correlated with male gender (p=0.02).
- Low weight-for-age and weight-for-height correlated with increased age (p<0.001), low weight-for-age with raised alkaline phosphatase (p=0.04), and low BMI with reduced plasma albumin (p=0.04).
- No correlation was found between growth deficits and SI or anemia severity.
Conclusions:
- Children and adolescents with SCD in Yemen experience significant growth impairment.
- Integrating growth monitoring and nutritional support into the care of SCD patients is essential.
- These interventions are vital components of comprehensive management for SCD in this population.
Background:
Physical growth is known to be impaired in children with sickle cell disease (SCD) and the prevalence and severity vary with geographical location. The factors which contribute to this sub-optimal growth are poorly understood.
Objectives:
To describe the growth status of children and adolescents with SCD in Yemen using the new WHO reference values and to assess correlation of growth indicators with disease severity and with haematological and biochemical parameters.
Methods:
A cross-sectional study of children <16 years with SCD was conducted at Al-Wahda General Teaching Hospital, Aden. Anthropometric measurements of weight, length/height, mid-upper-arm circumference (MUAC) and body mass index (BMI) were collected. Disease severity was assessed using a severity index (SI) score.
Results:
A total of 102 children (56 male) were included and their mean age was 7.2 years (range 6 months to 15 years). Low weight, height and BMI-for-age Z-scores (<-2 SD) were observed in 45%, 54% and 35% of children, respectively. Regression analyses indicated an association of low height-for-age with male gender (p=0.02), low weight-for-age and weight-for-height with increased age (both p<0.001), low weight-for-age with raised alkaline phosphatase (p=0.04), and low BMI with reduced plasma albumin (p=0.04). There was no correlation between growth deficits and SI or anaemia severity.
Conclusion:
Growth is severely impaired in children and adolescents with SCD in Yemen. Growth monitoring and nutritional support should be included in their comprehensive care package.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
