ABSTRACT
The study on sub clinical rickets is unique in the sense that it has not been preplanned conducted anywhere especially in Pakistan. The objective of present study was to explore the prevalence, gender and geographical distribution of sub clinical rickets and their related factors among school students. Out of total participants, 189[90%] students were finally included in the study from rural, urban and suburban high schools of Hazara Division, KPK. The age of boys and girls students was 11 years to 16 years. Anthropometrics data along with daily intakes of meal and availability of sun shine was noted on record form. Sub clinical cases were diagnosed with abnormal biochemical findings without physical indications of rickets. Sub clinical rickets was found in 51[27%] students, out of which 15[8%] were boys and 36[19%] girls. Geographically, 26 cases of sub clinical rickets were from rural schools, 16 of urban and 09 found in suburban school. All sub clinical cases had serum level of sunshine vitamin D in between >/= 18nmol/l to
ABSTRACT
To determine the occurrence of subclinical rickets and its causing factors among adolescent students of schools in Kaghan Valley, Pakistan. Observation cross-sectional study. Department of Biochemistry and Health Sciences, Hazara University, Mansehra, Ayub Medical College and Teaching Hospital, Abbottabad, from March to April 2012. Sixty seven students [34 boys and 33 girls] age between 11 - 16 years included in the study from different schools of Kaghan Valley, Pakistan. Characteristic, serum biochemical and nutritional status were measured for all the participants. On the basis of biochemical finding the boys and girls students were divided in to two groups, normal subjects and subclinical rickets [absent symptoms with altered biochemistry]. Twenty six participants, 19 [73%] girls and 07 [27%] boys had biochemical abnormality but no clinical signs and symptoms of rickets. Low vitamin D and high alkaline phosphatase level were observed in 26 [100%], 21 [81%], low calcium in 17 [65%] and low phosphorus 7 [27%] subjects with subclinical rickets. None had high parathormone level above normal range. Nutritional intake of calcium, phosphorus and vitamin D was found less than the recommended daily intake in all the participants. Subclinical rickets is common problem among adolescent students especially in girls which is due to low nutritional intakes and avoidance of sunshine due to environmental and traditional impacts
