Study characteristics of juvenile diabetes mellitus cases in bangladesh.

Objective To identify the proportion and some selected characteristics of juvenile diabetics attending BIRDEM hospital. Materials and methods This was a cross sectional study. The study was conducted in the BIRDEM hospital. All Diabetic young aged up to 18 years who visit BIRDEM hospital were included in study population. The sample size was 240. Results It was observed that among the respondents 43.3% were protein deficient pancreatic diabetes (PDPD), 30.8% were Type-1 diabetes, 20% were fibro-calculus pancreatic diabetes (FCPD) and remaining 5.8% were Type-2 diabetes. Family history of diabetes was found among one-fifth of the respondents. It was found that majority 86.4% of Type-1 diabetes were presented in early age < 10 years in contrast to Type-2 diabetes 4.5%, PDPD 9.1% and FCPD 0.0%. It was found that 50% of type-1 diabetes patient and 17.6% of Type-2 diabetes patient were from urban area and 24.5% of FCDP patient and 52.8% of PDPD patient were from rural areas. It was observed that Type-1 and Type-2 diabetes were associated with the family history of diabetes mellitus than FCPD and PDPD. Severe underweight and sever stunted was significantly higher among the protein deficient diabetes mellitus compare to Type-2 diabetes. Conclusion Juvenile diabetes is emerging health problem in modern era. Like old population the incidence of juvenile diabetes is increasing day by day. It is time for the health planner to prevent and control the disease; otherwise it will be major problem after a decade.


Introduction Introduction Introduction Introduction 1
Bangladesh is a developing country; here communicable diseases and nutritional problem, over population are priority problem for public health sector. Consequently, non communicable diseases, such as diabetes mellitus, ishcaemic heart diseases, hypertension, which are lifelong chronic illness, with risk of life threatening complications are getting less priority. Diabetes mellitus, a chronic disease once thought to be uncommon in the developing world, has now emerged as an important public health problem in Asia (1). It is a major and growing health problem at all ages and in all countries. It is also the commonest endocrine disorder amongst the young and adolescents. Usually it causes prolonged ill health and early death. In young, growth failure and delayed puberty are well documented (2).
In Bangladesh, there has not been any epidemiological study on juvenile diabetes. Recent studies from the Asian sub-continent showed an increasing prevalence of diabetes in young (3). In Bangladesh like many other developing countries the number of new cases of diabetes is increasing every year. Unfortunately, there is still inadequate awareness about the real dimension of the problem among the general public in the South-East Asia region. There is lack of awareness about the existing interventions for preventing diabetes and the management of complications. Poor detection of cases, sub-optimal treatment, and insufficient follow up leading to unnecessary disabilities and severe complications, often result in early death (4). In addition to Type-2 DM, which is rather silent, chronic, often unidentified killer mostly among the adult population, the Type-1 DM makes more dramatic appearance in affected young. They develop symptoms of ketoacidosis and often die, since the majorities do not have access to adequate medical care and since insulin is often either not available or too expensive (2).
Almost all of these deaths would be preventable if free or subsidized insulin and adequate health care services were available (3). The prevalence of insulin dependent diabetes in young is 0.26 per thousand in the urban area in south India. But the prevalence of other Asian countries likes Japan 0.06 per thousand and China 0.09 per thousand is lower than India (5). However, this is much less than the prevalence reported from North Europe 2.1 per thousand (6). Till now there is no study on the prevalence of juvenile diabetes in our country.
There are several factors identified in different studies in different countries, which are associated with juvenile diabetes, but there is no such study conducted in our country. The type of diabetes are seen in our country is different from developed country and it is very much essential to identify the risk factors to prevent the disease.
Finding of this study will help in the research field and also the planner to develop appropriate policy and programs for prevention and control of juvenile diabetes.

Materials and methods Materials and methods Materials and methods Materials and methods
This was a cross sectional study. The study was conducted in the BIRDEM hospital. Total 240 diabetic patients selected purposively. Designed questionnaire was used for data collection. The questionnaire was pre-tested before final used for data collection. Data were collected by face to face interview by questionnaire and checklist. All patients aged up to 18 years with diabetes who come to the BIRDEM for their treatment and for follow-up were included in the study population. After completion of interview, anthropometric measurements of the studied patients were taken. Data on height, weight, mid arm circumference and skin fold thickness of the studied patients were taken through standard instruments. All the data which were checked for integrity and collected from field were entered for analysis by using SPSS software program.

Results Results Results
It was found that Type-1 50.0% and Type-2 17.6% diabetes mellitus were high among the urban patients. FCPD 24.5% in rural areas and PDPD 54.5% in sub urban areas and the difference were statistically significant (p<0.001) ( Table 1).
Study revealed that the type-1. 33.3% and PDPD 44.4% were high among the boys, whereas Type II 6.0% and FCPD 21.4% were high among the girls, but the difference was not statistically significant (p>0.05) ( Table 2).
Result found that Type I and Type-2 diabetes mellitus were significantly associated with family history of diabetes mellitus than FCPD and PDPD (p<0.05) ( Table 3).

It was observed that out of 240 diabetic patients, 10.8% were normal height for age, 42.5% stunted, 30.0% moderately stunted and 16.7% were severely stunted. It was evident that significant severe stunted was associated with protein deficient diabetes mellitus compared with Type-II diabetes mellitus (p<0.001), but no statistically significant mean difference was found among the other two types of diabetes mellitus such as Type-I and FCPD (p>0.05) shows the relationship of different types of diabetes mellitus with height for age, which was calculated by Z-score of NCHS. It was observed that out of 240 diabetic patients, 10.8% were normal height for age, 42.5% stunted, 30.0% moderately stunted and 16.7% were severely stunted. It was evident that significant severe stunted was associated with Protein deficient diabetes mellitus compared with Type II diabetes mellitus (p<0.001), but no statistically significant mean difference was found among the other two types of diabetes mellitus such as Type-I and FCPD (p>0.05) ( Table 4).

Height for age Type of DM n (%) Total
It was observed that out 240 diabetic patients 43.3% were PDPD followed by Type-I diabetes mellitus 30.8%, FCPD 20.0% and lowest Type-II diabetes mellitus 5.7% (Figure 1).

Discussion Discussion Discussion
This cross sectional study was conducted in the BIRDEM hospital to find out the proportion and some selected characteristics of juvenile diabetes.
Regarding age, we have found that eighty two percent of respondents were found in age group 10-19 years. This finding is consistent with a study in Italy by Cotellessa (7), where result shows that agespecific incidence rate is higher in the 10 to 14 year old age group.
Regarding sex distribution, majority of the respondents were female and remaining were male and female to male ratio was 2.3:1, similar finding was found study done by Abdullah (2). Such observations have been found in India study done by Ramachandra (4).
Regarding type of Diabetes mellitus results shown that percent of PDPD was higher than Type-1diabetes, Vol. 8  FCDP and Type-2 diabetes; this finding is almost similar to the finding of study done by Abdullah and Svensson (2,8).
Regarding status of diabetes pattern in urban and rural area it was seen that Geographical variation in occurrence of type-1 diabetes has been studied study done by Karvonen, study finding is consistent in our study (9).
Regarding family history of diabetes it was evident that Type-1 and Type-11 diabetes were significantly associated with positive history of diabetes than FCPD and PDPD. Similar observation was found in study done by Kida (10).
As regard as nutritional status of the respondents it was observed that severe stunting were significantly associated with protein deficient diabetes mellitus compared with Type-11 diabetes mellitus, study done by Svensson that finding is consistent with our study (8).

Conclusion Conclusion Conclusion Conclusion
In this study it was observed that among the respondents, more than two-fifth were PDPD, more than one fifth were Type-l diabetes, one fifth were FCPD and remaining were Type-2 diabetes. Type-l diabetes is found predominantly in younger age group and Type-2; FCPD and PDPD are found in age group more than 10 years. It was observed that Type-l diabetes and Type2 diabetes were higher among urban areas and FCPD and PDPD were more among rural areas. Type-l and Type-2 diabetes were significantly associated with the family history of diabetes mellitus than FCPD and PDPD. Severely underweight and severe stunted younger were significantly higher among the protein deficient diabetes mellitus compared to Type-2 diabetes.
