ABSTRACT
Background: To determine the association between the serum vitamin D levels with the control and severity of asthma.Methods: A total of 113 asthmatic children were enrolled in the study who were on regular follow-up and treatment for the past 6 or more months. The demographic details, presenting complaints, aggravating factors, allergic rhinitis, atopic dermatitis, hospital and ICU stay, duration of sunlight exposure, drug compliance and detailed clinical examination findings were noted in the predesigned proforma. Control of asthma was assessed based on GINA guidelines 2018 as well controlled, partly controlled and poorly controlled. The partly controlled and the poorly controlled group were further combined and labelled as not well controlled group. Severity of asthma was categorized into intermittent, mild persistent, moderate persistent and severe persistent. Serum 25 hydroxy vitamin D was assessed by solid phase ELISA. The well controlled and partly controlled group were compared for all studied parameters.Results: Asthma status of the subjects was categorized as well controlled (59%) as partly controlled (40%) and as poorly controlled (1%). Children with partly and poorly controlled asthma had significantly more vitamin D deficiency (10.9%) and insufficiency (32.6%) compared to well controlled group (4.5% and 4.5% respectively), with p value= 0.000. Low serum vitamin D levels are significantly associated with moderate and severe persistent asthma (p value= 0.009). Exercise significantly induced symptoms in 47.8% of not well controlled group and about 25.4% in well controlled group (p value= 0.014). Examination findings such as wheeze on auscultation was significantly more in not well controlled group.Conclusions: Low serum vitamin D levels are associated with poor control of asthma in children and the severity of asthma is inversely proportional to the serum vitamin D levels.
ABSTRACT
Background: Most of the studies on cardiovascular risk factors are concentrated on adults. But atherosclerotic process begins in childhood and is influenced by genetics, diet and life style. Hence, present study was undertaken. The objectives of the study were to study lipid profile and other cardiovascular risk factors like hypertensive status, BMI(Body mass index) in children aged between 5years and 18 years born to parents having premature IHD(Ischemic heart disease), to study diet and life style factors in study group having family history of IHD, to study the sociodemographic profile of dyslipidemia.Methods: A 200 Cases of premature IHD were selected. Their children(n=200) in the age group of 5 to 18 years were selected and analysed for cardiovascular risk factors. They were compared with 200 normal children without any family history of IHD.Results: On comparison of mean lipid profile between cases and controls HDL cholesterol was very low amongst cases (p=0.001). The mean values of triglycerides and VLDL were very high amongst cases (p=0.001). The mean atherogenic index (AI) was high amongst cases (p=0.001). Prehypertension or hypertension was seen amongst 8.5% cases (p=0.004). Amongst the cases 19.5% had excess junk food intake (p=0.001). 51.5% of cases had sedentary life style (p=0.001).Conclusions: Children in our area born to parents with premature IHD have significant incidence of dyslipidaemia. There is an increased incidence of other cardiovascular risk factors like hypertension, excess junk food intake, sedentary life style in these children.
