Executive summary:
The study Vitamin D among various age & sex groups at DPRC Hospital, Dhaka” conducted among 246 purposively selected male & female patients who visited Dhaka Pain & Rehabilitation Center (DPRC) hospital located at Ring Road, Shyamoli Adabor, Mohammadpur Dhaka from January – September, 2017. The study objective was to explore the vitamin D level in various age groups and sex. The study also analyzed difference in vitamin D level among various age groups and sexes. The respondents were divided in various age groups (for example 1 – 20, 21 – 30 years). Vitamin D level was obtained through chemical test at DPRC laboratory using the blood sample of the patients participated in the study. A simple one page questionnaire was used to record the results. It was a cross sectional study.
A total 246 respondents vitamin D level was tested using blood sample (52.0% male, 48.0% female) at Dhaka Pain & Rehabilitation Center (DPRC hospital) located at Ring road, Adabor Shyamoli, Mohammadpur, Dhaka. Majority of the patients/respondents was in the age range from 31 – 60 years (22.4% in the age group 41 – 50 years, 21.5% in the age group 51 – 60 years & 17.5% in the age group 31 – 40 years. The mean age was 47.04 years, ranging from 4 to 90 years. Above half of the patient’s vitamin D level (54.9%, 135) was in the range from 10 – 30 ng/ml, followed by 31 – 100 ng/ml with 40.2% (99 patients). Few were in the level 1 – 9 ng/ml (10 patients, 4.1%). Only 2 patients (08%) vitamin D level recorded above 100 ng/ml. The mean vitamin D level of 246 patients was 31.7683, ranging from 3.18 – 114.30 ng/ml. The vitamin D level 10 – 30 ng/ml was most evident among the both sexes. Though female patients were more prone to be within the vitamin D level 10 – 30 ng/ml than male (female 58.5%, 69 to 51.6%, 66). Vitamin D level ranging from 31 – 100 ng/ml was more prone to males than female patients (42.2%, 54 males to 38.1%, 45 females). Male patients were also more numerous in the vitamin D level 1 – 9 ng/ml than female (7, 5.5% to 3, 2.5%). Young respondents/patients (below 20 years) were found to possess vitamin D level better than older. The age group 1 – 20 years reported 46.1% (6 patients) with the vitamin D level 31 – 100 ng/ml, followed by 10 -30 ng/ml level with 38.5% (5 patients). The patients in the age group 21 – 30 years were mostly 10 -30 ng/ml vitamin D level 22 patients (71.0%), followed by 25.8% (8 patients). The age group 31 – 40 years also had shown the vitamin D level as the age group of young adults (24, 55.8% in the level 55.8% & 18, 41.9% in the level 31 – 100 ng/ml). The group 41 – 50 years showed 58.2% vitamin D level 10 -30 ng/ml & 36.3% in the level 31 – 100 ng/ml). 51 – 60 years showed the 49.0% (26 in 10 -30 ng/ml level) & 45.3% (24 in 31 – 100 ng/ml level). Half of the patients in the age group 61 – 70 years were in the level 10 -30 ng/ml & 47.0% (16 in 31 – 100 ng/ml). More than half 52.9% (9 patients) in the age group of above 70 years were in 10 – 30 ng/ml level & 41.2% (7 patients with 31 – 100 ng/ml).
This study was important to explore the vitamin D level among various age and sex in Bangladesh who were suffering from pain, paralysis and related physical problems required physiotherapy. Over all younger patients were tend to possess better vitamin D level than the older age groups. More than half of the patients vitamin D level were from 10 – 30 ng/ml express over all poor vitamin D level in Bangladesh.
Study objectives & Methodology:
The study was conducted among 246 purposively selected male & female patients at DPRC Hospital from January – September, 2017 with the objective of exploring the vitamin D level in various age groups and sex. The study analyzed difference in vitamin D level among various age groups and sexes. The respondents were divided in various age groups (for example 1 – 20, 21 – 30 years). Vitamin D level was obtained through chemical test at DPRC laboratory using the blood sample of the patients participated in the study. A simple one page questionnaire was used to record the results. It was a cross sectional study.
Results:
A total 246 respondents vitamin D level was tested using blood sample. Among the respondents males was slightly higher than female (52.0% male, 48.0% female). Majority of the patients/respondents was in the age range from 31 – 60 years, that is middle to little older in age. The largest frequency was observed for the age group 41 – 50 years (22.4%), followed by 51 – 60 years (21.5%) & the age group 31 – 40 years (17.5%). Among the remainder the age group 61 – 70 years was accounted in 13.8% cases and the young adult patients with the age group 21 – 30 years with 12.6%. The mean age was 47.04 years, ranging from 4 to 90 years. Above half of the patient’s vitamin D level (54.9%, 135 out of total 246 patients) was in the range from 10 – 30 ng/ml, followed by 31 – 100 ng/ml with 40.2% (99 patients). Few were in the level 1 – 9 ng/ml (10 patients, 4.1%). Only 2 patients (08%) vitamin D level recorded above 100 ng/ml. The mean vitamin D level of 246 patients was 31.7683, ranging from 3.18 – 114.30 ng/ml.

Sex difference of various vitamin D level groups (for example 1 – 9 ng/ml, 10 -30 ng/ml group) was explored. The vitamin D level 10 – 30 ng/ml was most evident among the both sexes. Though female patients were more prone to be within the vitamin D level 10 – 30 ng/ml than male (female 58.5%, 69 out of total 118 female patients to 51.6%, 66 out of total 128 male patients). Vitamin D level ranging from 31 – 100 ng/ml was more prone to males than female patients (42.2%, 54 males to 38.1%, 45 females). Male patients were also more numerous in the vitamin D level 1 – 9 ng/ml than female (7, 5.5% to 3, 2.5%). One male and one female was found with the vitamin D level more than 100 ng/ml.

Difference in vitamin D level in various age groups was analyzed. Young respondents/patients (below 20 years) were found to possess vitamin D level better than older. The age group 1 – 20 years reported 46.1% (6 patients) with the vitamin D level 31 – 100 ng/ml, followed by 10 -30 ng/ml level with 38.5% (5 patients). Young adults in the age group 21 – 30 years were mostly in the range 10 -30 ng/ml vitamin D level 22 patients (71.0%), followed by 25.8% (8 patients). The age group 31 – 40 years also had shown the vitamin D level as the age group of young adults (24, 55.8% in the level 55.8% & 18, 41.9% in the level 31 – 100 ng/ml). The age group 41 – 50 years showed 58.2% (32 patients in the vitamin D level 10 -30 ng/ml & 36.3% (20 patients in the level 31 – 100 ng/ml). The age group 51 – 60 years also showed the same vitamin D level, 49.0% (26 in 10 -30 ng/ml level) & 45.3% (24 in 31 – 100 ng/ml level). Half of the patients in the age group 61 – 70 years were in the level 10 -30 ng/ml & 47.0% (16 in 31 – 100 ng/ml). More than half 52.9% (9 patients) in the age group of above 70 years were in 10 – 30 ng/ml level & 41.2% (7 patients with 31 – 100 ng/ml).
Conclusion:
This study was important to explore the vitamin D level among various age and sex in Bangladesh who were suffering from pain, paralysis and related physical problems required physiotherapy. Over all younger patients were tend to possess better vitamin D level than the older age groups. More than half of the patient’s vitamin D level was from 10 – 30 ng/ml express over all poor vitamin D level in Bangladesh.
