Adherence to 24-hour movement guidelines and their association with depressive symptoms in adolescents: Evidence from Bangladesh

Healthy movement behaviours are associated with various physical and mental wellbeing; however, little is known about such associations in low- and middle-income countries. The aim of this study was to examine adherence to 24-hour (h) movement guidelines and their relationship with depressive symptoms in adolescents. Data were from 312 Bangladeshi adolescents aged 13-17 years (42% female). Meeting the guidelines was defined as: energy expenditure for physical activity (PA) ​≥ ​1 680 Metabolic Equivalent of Task (MET)-min/week, ≤ 2 ​h/day of recreational screen time (ST), and 8-10 ​h/night of sleep. Depressive symptoms were assessed using the 10-item Center for Epidemiological Studies Depression Scale (CESD-10) with a score of 10 or more indicating high depressive symptoms. Percentage of adolescents meeting the three recommendations was 2.2%, with 17.6% meeting two, and 31.2% meeting one recommendation. Generalized estimating equations showed that odds of having high depressive symptoms was a third (odds ratio [OR] ​= ​0.35, 95% confidence interval [CI], 0.19-0.57) for meeting the PA guidelines, and about a half (OR = 0.47, 95%CI, 0.18-0.87) for meeting the sleep guidelines. Odds of depressive symptoms reduced significantly for meeting PA and sleep (OR = 0.20, 95%CI, 0.09-0.59), or PA and ST (OR ​= ​0.24, 95%CI, 0.08-0.55) guidelines. About half of the adolescents did not meet any recommendations, which underscores the need for public health campaigns to promote adherence to the movement guidelines in this pediatric population. Further longitudinal research with larger sample size is recommended to explore the inter-relationships of these behaviours and their impact on health and wellbeing outcomes of adolescents in Bangladesh.

Effects of a School-Based Physical Activity Intervention on Adolescents' Mental Health: A Cluster Randomized Controlled Trial

BACKGROUND

The aim of this study was to evaluate the effectiveness of a school-based multicomponent physical activity intervention on mental health of adolescents.

METHODS

A clustered, randomized, controlled trial was employed in 8 high schools in Dhaka, Bangladesh, which were randomly assigned to either an intervention or control group; 40 students in grades 8 and 9 from each school took part in the trial (n = 160/group). Students in the intervention schools participated in a 12-week physical activity intervention with multiple components (eg, supervised circuits, lunchtime sports, health education, infographics), while control schools received no intervention. Participants completed baseline and postintervention surveys measuring depressive symptoms (Center for Epidemiologic Studies Depression Scale) and life satisfaction (Cantril Ladder), along with other sociodemographic and behavioral characteristics. Linear mixed-effects modeling was used to evaluate the intervention effects.

RESULTS

Depressive symptoms in the intervention group decreased at postintervention, but remained stable in the control group. There was an increase in life satisfaction in the intervention group and a decrease in the control group. Multivariable modeling showed that students in the intervention group had a significantly lower level of depressive symptoms (β = -4.60; 95% confidence interval, -5.76 to -3.46) and higher level of life satisfaction (β = 1.43; 95% confidence interval, 0.77 to 2.10) compared with their counterparts in the control group. Sensitivity analyses supported the positive effects of the intervention.

CONCLUSIONS

Our school-based, multicomponent physical activity intervention is effective in improving mental health indicators in adolescents. Future trials should be ramped up to include schools in rural and regional settings, using robust measures  of mental well-being.

Effects of behavioural change communication (BCC) on menstrual hygiene practices among urban school adolescent girls: a pilot study

Background

Research on menstrual hygiene management practices (MHMP) has yet to be conducted among adolescent girls in Bangladesh who have gained services from the Urban Primary Health Care Project (UPHCP). This study aimed to assess the effects of behavioural change communication activities on MHMP among urban school adolescent girls.

Methods

A convenience sample of 270 adolescent girls (aged 10-19) who had no chronic diseases from 5 schools in Dhaka city was selected using a descriptive cross-sectional design from February to May 2018. A semistructured (interviewer-administered) questionnaire was used. Frequencies were calculated for descriptive analysis.

Results

About 17% of girls had irregular menstrual cycles, 57% felt uneasy and 27% had >7 days of menstrual flow. Fifty-five per cent of the girls used sanitary napkins. Most (95%) and 26% of the girls did not change their pads during school and at night, respectively. Sixty-five per cent of girls disposed of the used pads at the public dustbin, and 83% bathed during menstrual. Only 4% of girls were aware of the iron folic acid tablets.

Conclusions

Despite the availability of services from UPHCP, the acceptance and adherence to MHMP among adolescent girls still need to be improved.

Effectiveness of a school-based intervention on physical activity and screen time among adolescents

OBJECTIVES

To evaluate the effectiveness of a multi-component school-based intervention on physical activity (PA) and screen time (ST) among urban adolescents in Bangladesh.

DESIGN

Cluster-randomised controlled trial.

METHODS

Eight high schools were randomly assigned to either intervention group (IG) or control group (CG). Participants (n = 160 per group, 40 school) were in grades 8-9. A 12-week multi-component intervention was developed based on the WHO's Health-Promoting Schools framework. The IG received weekly supervised circuit exercise (30 min/week), health education session (10 min/week) with health educational materials, and lunchtime sports activities (20 min/week). The main outcome measures included self-reported PA, ST, knowledge on PA and SB, which were assessed at baseline, 8 and 12 weeks. Repeated measures ANCOVA was used to evaluate the intervention effects.

RESULTS

Total PA (MET-min/week) was increased from baseline to 8 and 12 weeks in the IG (3%-5%) but decreased in the CG (5%-3%) and significantly improved in the IG compared to the CG (p < 0.001) over time. Average ST (min/day) reduced from baseline to 8 and 12 weeks in the IG (28%-35%), while remained unchanged in the CG (6%-5%). The IG had a significantly lower average ST than the CG at 12 weeks. The average knowledge scores on PA and SB were significantly higher in the IG than the CG at 12 weeks (p < 0.001).

CONCLUSIONS

Our intervention has demonstrated some promising effects on increasing PA, reducing ST, and improving PA and SB knowledge. This study underscores the need for a scaled-up evaluation in other locations including rural settings.

Prevalence and factors associated with depression among the mothers of school-going children in Dhaka city, Bangladesh: A multi stage sampling-based study

Background

Motherhood is associated with extra stress, and mothers of young children are particularly prone to developing depression and mental health problems.

Methodology

This analytical cross-sectional study was conducted in Dhaka city, Bangladesh, from June to December 2019. Mothers of school-going children were recruited through a multistage sampling technique. Dhaka city was divided into two divisions and then further subdivided into public and private sectors. Six schools were selected from each sector by using a simple random sampling technique. A list of class five to eight students were collected from each school by systematic random sampling. Data were collected through face-to-face interviews using semi-structured questionnaires. The rate of depressive symptoms was measured by the validated Zung Self-Rating Depression Scale (SDS).

Result

A total of 324 women participated in this study; the majority of the women (85.5%) were Muslim, 67.0% were housewives, and 53.1% had a girl child. Among the women, 15.4% had mild, 22.2% had moderate, and 20.1% had severe depression. Most of the child's behavioral and lifestyle factors were associated with the mother's depression. Adjusted analyses indicate that if a child is often unhappy, depressed, or tearful [(OR (95%CI = 22.27 (8.39-59.11)], gets nervous in new situations or easily loses confidence [(OR (95%CI) = 5.45 (2.96-10.00)], often lies or cheats [(OR (95%CI) = 8.93 (3.76-21.22)], gets afraid easily [(OR (95%CI) = 7.09 (3.79-13.24)], watches television for 3 h or more [(OR (95%CI) = 23.77 (6.46-87.48)] browses the internet for 3 h or more [(OR (95%CI = 7.37 (2.76-19.67)] were associated with mother's depression.

Conclusion

The study concludes that depression among the mothers of school-going children in Dhaka city of Bangladesh is high. Several lifestyles and behavioral factors of school-going children are significantly associated with the mothers' depression.

Association between physical activity and diabetic complications among Bangladeshi type 2 diabetic patients

BACKGROUND

The aim of the study was to assess the association of physical activity (PA) with the presence of diabetes related complications among Bangladeshi type 2 diabetic subjects.

METHODS

This cross-sectional study was conducted in the Out Patient Department (OPD) of BIRDEM, Bangladesh. A group of 977 subjects were randomly selected and followed up. Diabetes was diagnosed following the WHO study group criteria. The level of PA was categorized into inactive/low (<150 min/week) and moderate-to-vigorous (≥150 min/week). The WHO recommended Asian criteria was used to identify general obesity. Retinopathy was detected by fundal photography, CKD by serum creatinine and hypertension was diagnosed clinically. Univariate and multivariate analyses were used to assess the associations of PA with diabetes related complications.

RESULTS

Out of the 977 subjects investigated, 468 were male and 509 were female (mean ± SD of age, 56 ± 8 years). In the study subjects, 74% were either inactive or in low PA and of them 65.1% were overweight/obese. Analysis showed that inactive/low PA was associated with all the three diabetes related complications (p < 0.001)-hypertension, retinopathy, and nephropathy. Multivariate analysis showed that inactive/low level of PA was strongly associated with complications like retinopathy (p < 0.001) and hypertension (p = 0.01) in the female patients. It was also found to be highly associated with retinopathy (p < 0.001) among the male patients.

CONCLUSION

A large number of urban Bangladeshi population are involved only in low PA or remain inactive themselves, which is leading to obesity and it seems to have a strong association with diabetes related complications in this population.

Nutritional beliefs and practices among diabetic pregnant mothers in a tertiary care hospital in Bangladesh

BACKGROUND & AIM

Pregnant mothers with diabetes, especially in developing countries, are particularly prone to suffer from dietary imbalances due to superstitions and irrational beliefs and practices. The study aimed to explore the existing beliefs and practices related to food intake among Bangladeshi diabetic pregnant mothers.

MATERIAL & METHODS

A cross-sectional study was conducted among 200 diabetic pregnant mothers (age in yrs, M±SD, 30±4), selected purposively from outpatient department of Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine & Metabolic Disorders. An interviewer-administered questionnaire was used to collect data. SPSS 16.0 were used for data analysis.

RESULTS

About 40% mothers had uncontrolled glycaemic status. 43% mothers believed that food should not be taken during the 'call for prayer' and 91% of them practiced it. For 'eclipse' the percentage of such kind of belief was much higher (80%) and 90% of them practiced it. With varying proportion for particular fishes 44-58% respondents believed that some fishes should be avoided due to the increased movement of child, fetal malformation and disease. 93% actually practiced it. 28% had adverse beliefs about duck meat, 78% pineapple and 8% had about coconut. The corresponding percentages for practice were 82%, 99% and 50% respectively. Mentally and physically abnormal child, different kinds of child illness and threat of abortion were among the reasons for misbeliefs about those foods.

CONCLUSION

There are a number of nonscientific beliefs and prejudices among this pregnant mother regarding the intake of food.

Ocular knowledge and practice among type 2 diabetic patients in a tertiary care hospital in Bangladesh

Background and aims

Diabetes mellitus is likely to have a major effect on vision, and adequate knowledge of its ocular manifestations is of substantial importance to diabetic patients. The study aimed to assess the ocular knowledge and practices among Type 2 diabetic patients of Bangladesh.

Methods

This cross-sectional study included 122 diabetic patients from the outpatient department (OPD) of the apex diabetic healthcare hospital of the country under the sponsorship of the Diabetic Association of Bangladesh (BIRDEM). A questionnaire was used for collecting data on knowledge on and practices relating to diabetes mellitus with particular emphasis on ocular issues. A predefined score was used for categorizing levels of knowledge and practices as poor, average, and good.

Results

Of the 122 respondents, 63%, 55%, 40%, 44%, and 30% reported, blindness, retinopathy, cataracts, glaucoma, and double vision respectively, as complications of diabetes mellitus. About 50% were aware of the need for eye screening for people with the complications. Only 8% monitored their blood glucose levels daily, 15% monitored weekly, and 10% reported checking their blood pressure daily and 43% took their medications as prescribed. The level of diabetic knowledge was poor, moderate and good, respectively, among 24%, 56%, and 20% of the respondents, whereas the practice standards showed that 47%, 31%, and 22% had poor, average, and good levels respectively. The knowledge score was significantly associated with the practice score (r = 0.460, p = 0.001).

Conclusion

The results indicate that the ocular knowledge and practices among diabetic patients attending a tertiary-care hospital in Bangladesh is average. Health and eye-care practitioners need to expand diabetic health education and promotion among diabetic patients.

Factors associated with maternal anaemia among pregnant women in Dhaka city

Background

Maternal anaemia is a common problem in pregnancy, particularly in developing countries. The study was aimed at determining the factors associated with anaemia among a group of pregnant mothers who attended an antenatal clinic in Dhaka city.

Methods

This cross-sectional study included 224 pregnant women, who visited the antenatal clinic of the Marie Stops, Dhaka. Demographic data and information on maternal age, gestational age, educational and income level, and socioeconomic status were collected from all the subjects. Haemoglobin status was measured to assess their anaemia. A qualified technician drew venous blood samples from them. The reference values of haemoglobin were categorized according to the World Health Organization (WHO) criteria as follows: normal (11 g/dL or higher), mild (10–10.9 g/dL), and moderate (7–9.9 g/dL). Mild and moderate levels of haemoglobin were defined as anaemic (haemoglobin levels of <11 g/dL). The SPSS software (Windows version 16.0. SPSS Inc, Chicago, USA) was used for analyzing data.

Results

The mean (±SD) age of the subjects was 26.4 ± 2.81 years. Sixty-three percent of the subjects had normal level of haemoglobin, and 37 % were anaemic 26 % mild and 11 % moderate. Maternal anaemia was significantly associated with age (p = 0.036), education (p = 0.002), income (p = 0.001), living area (p = 0.031). Results of binary logistic regression analysis showed that maternal anaemia was also significantly associated with age (p = 0.006), educational status (primary to 8th grade, p = 0.004; secondary and above, p = 0.002), living area (0.022), and income (0.021).

Discussion

A significant proportion of pregnant women were found anaemic. Most data showed education has animpact on awareness to use of health services and iron supplementation should be encouraged to improve the haemoglobin levels in pregnancy.

Conclusions

The results indicate that anaemia is alarmingly high among pregnant women in Dhaka city. Maternal anaemia is associated with age, education level, income level, and living area. The results suggest that pregnant women and members of their families should be urgently educated to understand the importance of antenatal care.

A Comparative Study on Knowledge about Reproductive Health among Urban and Rural Women of Bangladesh

OBJECTIVE

To compare the level of knowledge on reproductive health among urban and rural women of selected area of Bangladesh.

MATERIALS AND METHODS

A descriptive cross-sectional study was undertaken among 200 women selected purposively from different rural and urban areas of Bangladesh. Data were collected using a semi-structured interviewer-administered questionnaire by face to face interview. Knowledge level was analyzed according to poor, moderate and good knowledge by pre-defined knowledge scoring.

RESULTS

Mean age of the respondents was 26 years and majority (66%) of them was housewives. Most of them (61%) had completed their primary level education. Around three-fourth of them belongs to lower-middle income group. Overall level of reproductive health knowledge was more evident among urban reproductive aged women than rural counterparts (p < 0.001). Moreover, significant knowledge gap was found regarding family planning (p = 0.005), care during pregnancy (p < 0.001), safe motherhood (p = 0.002), newborn care (p = 0.009) and birth spacing (p <0.001) between urban and rural women. Family members were the major source of information in both groups.

CONCLUSION

A wide knowledge gap was found between Bangladeshi urban and rural respondents regarding their reproductive behaviors. Government and concerned organizations should promote and strengthen various health education programs to focus on reproductive health, especially among reproductive aged women in rural area.

Determinants of overweight and obesity among Bangladeshi diabetic women of reproductive age

BACKGROUND

Several reproductive disorders with overweight and obesity are now known to be associated with insulin resistance. The study was aimed to assess the proportion and determinants of overweight and obesity among diabetic women of reproductive age.

METHODS

This cross-sectional analytic study was conducted among 888 diabetic women of reproductive age attending the out-patient department (OPD) of the central hospital of the Diabetic Association. Body Mass Index (BMI) was used to assess the general obesity. Waist Circumference (WC), Waist-Hip Ratio (WHR) and Waist-Height Ratio (WHtR) were used to assess central obesity.

RESULTS

The overall prevalence of overweight was 22% (95% CI 19-24) and that of obesity was 48% (95% CI 45-51). Prevalence of central obesity by waist circumference was 77%, by waist-hip ratio was 99.9% and by waist-height ratio was 89%. Overweight and obesity were higher in the age group of 45-49 years (49%) and 35-44 years (24%) respectively. On Pearson's correlation analysis, BMI and WC were significantly correlated with age (r = 0.135, p = 0.001; r = 0.162, p = 0.001) and income (r = 0.151, p = 0.001; r = 0.087, p = 0.009) respectively. WHR was also correlated with income (r = 0.094, p = 0.005). Moreover, WHtR was significantly correlated with age (r =  0.139, p = 0.001), income (r = 0.069, p = 0.04) and duration of diabetes (r = 0.073, p = 0.03).On binary logistic regression analysis, BMI was significantly associated with age, income and management of diabetes by Oral Hypoglycemic Agent (OHA) (p < 0.05). WC was significantly associated with age, income and management of diabetes by OHA and insulin (p < 0.05). Where, WHR was significantly associated only with duration of diabetes (p < 0.05). WHtR was significantly associated with age (p < 0.05), management of diabetes by OHA (p < 0.05) and insulin (p < 0.05) in this analysis.

CONCLUSIONS

A high prevalence of both overweight and obesity exists in diabetic women of reproductive age in Bangladesh and it seems to be associated with increasing age, income, duration of diabetes, and use of oral hypoglycemic agents.

Nutritional Status of Settler and Indigenous Women of Reproductive Age Group in Khagrachari District, Bangladesh

Background: Reproductive health is closely related with nutritional status of a country. Women are regarded as the nerve centers of the families and society, maternal nutrition and health is considered as the most important regulator of human fetal growth. Objective: This study was conducted with a view to assess the nutritional status of settler and indigenous women of reproductive age group (15--49 years) in Khagrachari district. Materials and Methods: This cross sectional study was done in the purposively selected Panchari thana of Khagrachari district in Bangladesh from 01 May to 31 August 2013. A total of 200 reproductive aged women were interviewed. Among them 100 were indigenous and 100 were settlers. Their anthropometric measurements were taken and nutritional status was determined by body mass index (BMI) recommended by World Health Organization (WHO) for Asian people. Results: The mean age of the respondents was 29.8 ± 11.1 years and maximum were in the age group of 15--24 years. Among the indigenous subjects Chakma, Marma, Tripura and Boisnu were 20.5%, 20.5%, 6.5% and 2.5% respectively. Among 100 indigenous reproductive aged women 17 were underweight; but among settlers 19 were underweight. Forty nine settler women were normal and in case of indigenous women 46 were normal. But regarding overweight indigenous women went ahead than settler women and obesity was found equal in both groups. Mean difference of mid upper arm circumference (MUAC) was significantly different (p<0.005) between the groups. Conclusion: This study provided a vivid picture of the nutritional status of the settler and indigenous reproductive aged women.

Diagnostic accuracy of direct ophthalmoscopy for detection of diabetic retinopathy using fundus photographs as a reference standard

AIMS

To determine the diagnostic accuracy of direct ophthalmoscopy for the presence and severity of diabetic retinopathy (DR) using fundus photographs as a reference standard.

METHODS

Patients with type 2 diabetes attending the outpatient department (OPD) of a tertiary care diabetes center, from October 2009 to March 2010 were recruited in the study after obtaining signed informed consent. Patients with type 1 diabetes and gestational diabetes or having eye problems were excluded. After checking visual acuity, direct ophthalmoscopy of each eye was done by diabetologist, followed by photography of two fields of retina by fundus camera. DR was graded by a retinal specialist, according to International Diabetic Retinopathy Disease Severity Scale. According to severity, patients with DR were grouped into non-sight threatening diabetic retinopathy (NSTDR) and sight threatening diabetic retinopathy (STDR). Sensitivity and specificity of direct ophthalmoscopy for detection of any retinopathy, NSTDR and STDR was calculated.

RESULTS

A total of 728 eyes were examined by direct ophthalmoscopy as well as fundus photography. Sensitivity (95% CI) of direct ophthalmoscopy for any retinopathy, NSTDR and STDR was found to be 55.67% (50.58-60.78), 37.63% (32.67-42.59) and 68.25% (63.48-73.02) respectively. Whereas, specificity of direct ophthalmoscopy was found to be 76.78% (72.45-81.11), 71.27% (CI: 66.63-75.91) and 90.0% (86.93-93.07) for any retinopathy, NSTDR and STDR respectively.

CONCLUSION

The sensitivity and specificity of direct ophthalmoscopy performed by the diabetologist for the presence and severity of DR was lower compared to the recommended level of sensitivity and specificity of a screening test of DR.

The Metabolic Syndrome: Comparison of Newly Proposed IDF, Modified ATP III and WHO Criteria and their Agreements

Background: Metabolic syndrome (MS) results from clustering of cardiovascular risk factors occurring in association with insulin resistance and obesity. With the increasing prevalence of obesity worldwide, MS is of keen interest in research. The disorder is defined in various ways, but one consolidated definition is needed to make studies comparable worldwide. The study was to determine the risk factors of metabolic syndrome in Bangladesh and comparison of newly proposed definition of International Diabetes Federation (IDF), modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) and the World Health Organization (WHO) criteria and their agreements. Materials and Methods: This was a cross sectional hospital based study. We randomly selected 229 participants. After obtaining informed written consent data collectors collected data by interview, clinical examination, anthropometric measurement and investigations. We calculated independent sample t-test means between to distinguish which risk factors were present in participants with and without MS, using SPSS v17. Results: The percentage of risk factors of MS among subjects according to different criteria was 72% of Modified ATP-III, 69% of IDF and 39% of WHO definition .In Modified NCEP ATP III when did independent sample t-test mean of BMI, waist circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose, high density lipoprotein and triglyceride were present statistically significant difference between without MS and with MS (p<0.05). According to WHO criteria BMI, waist circumference, fasting blood glucose were statistically significant (p<0.05) and similarly fasting blood glucose & triglyceride were statistically significant difference between without MS and with MS (p<0.05) according to IDF criteria.ATP III and WHO criteria showed good agreement (k 0.56) compared to ATP III with IDF (k 0.31) and WHO with IDF (k 0.11) criteria. Conclusion: Metabolic syndrome is highly prevalent in Bangladesh. We detected the highest proportion of participants with MS using the ATP III definition, which emphasizes the predominant focus on the modified waist circumference for Asian participants. However, MS prevalence following WHO criteria in those with impaired glucose regulation is comparable with ATP III definition. Follow up study needed to examine the significance of MS following all definitions for the assessment of risk for diabetes and or cardiovascular disease.

Incidence of diabetic retinopathy in Bangladesh: a 15-year follow-up study

BACKGROUND

The aim of the present study was to estimate the incidence of diabetic retinopathy (DR) among type 2 diabetic (T2D) subjects in Bangladesh.

METHODS

A random sample of 977 patients with T2D was recruited retrospectively in 2008 from newly diagnosed T2D patients who had attended the Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorder (BIRDEM) in 1993. Baseline information for the cohort was collected for 1993 from hospital records. The mean time until development of DR in newly diagnosed T2D patients was calculated using survival analysis. Cox's proportional hazards model was used to assess factors affecting the time until development of DR.

RESULTS

The cumulative incidence of DR over the 15-year period was 50.6% (95% confidence interval [CI] 47.5%-53.8%). The incidence density (per 100 person-years) of DR was similar in the overall cohort (4.1; 95% CI 3.7-4.5) and in men (4.2; 95% CI 3.7-4.7) and women (4.1; 95% CI 3.6-4.6) separately. The mean time (in years) until development of DR in the cohort was 9.72 (95% CI 9.38-10.06), with similar times in men (9.8; 95% CI 9.3-10.3) and women (9.6; 95% CI 9.5-10.1) analyzed separately. Age, sex, hypertension, lipid profile, HbA1c, and serum creatinine were entered into the hazards model simultaneously. However, only age (hazard ratio [HR] 0.75; 95% CI 0.61-0.92) and HbA1c (HR 0.52; 95% CI 0.33-0.82) had a significant effect on the time until development of DR.

CONCLUSIONS

Glucose deregulation is the most important factor in the development of DR.

Knowledge, Attitude and Practice of Type 2 Diabetic Patients Regarding Obesity: Study in a Tertiary Care Hospital in Bangladesh

Prevention and management of obesity largely depends on patient motivation and education and these, in turn, can be greatly facilitated by adequate baseline data on the knowledge, attitude and practice (KAP) of patients. The aim of this study is to assess KAP on obesity among Bangladeshi type 2 diabetics. Under a cross-sectional design 160 type 2 diabetics were selected from outpatient department of Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine & Metabolic Disorders. A standard questionnaire was constructed in local language and interview was administrated. Age and body mass index (BMI) of the respondents were 45.17±5.68 years and 25.6 ±4 kg/m² respectively. Among them 45% were male, 38% had primary education, 25% belonged to normal weight, 1/2 of them were overweight and rest were obese. KAP score of the respondents was [mean ±SD(%)] 60.03±13.82, 79.30±8.27, 55.50±19.21 respectively. Majority were unaware about ideal body weight, energy requirement and the weight measurement techniques. A substantial proportion of the respondents considered fast food, soft drinks, mayonnaise as healthier food. Majority of them positively agreed on willingness to follow proper diet, maintaining ideal body weight, dietary management and exercise. More than half of the normal weight and overweight respondents did exercise >45 min, while 1/3 obese did not do exercise (35%). KAP score were significantly associated with respondents’ level of education (P=0.0001, P=0.007, P=0.05 respectively) practice score was significantly associated with sex (P=0.0001), occupation (P=0.003) and BMI (P=0.0001). There is a need for increased effort towards developing and making education programs focusing on empowering the persons to transform their knowledge and attitude into practice.

Islet rejection in perforin-deficient mice: the role of perforin and Fas

BACKGROUND

Perforin and Fas are the two main pathways by which cytotoxic T lymphocytes (CTLs) mediate target cell lysis in vitro. The perforin pathway is predominantly used by CD8+ cells, which comprise the majority of CTLs. The Fas pathway has been demonstrated to be the principal cytolytic mechanism in CD4+ CTLs. CTLs have been shown to play an important role in allograft rejection. In this study, we examined the relevance of perforin and Fas to allograft rejection by transplanting pancreatic islets from fully allogeneic C3H/HeJ (C3H) or Fas-deficient C3H/lpr donors into perforin-deficient (P0) mice or controls with intact perforin genes (P2).

METHODS

P0 or P2 mice that were rendered diabetic with streptozotocin at 300 mg/kg i.p. received approximately 350 islets obtained from C3H or C3H/lpr donors by in situ collagenase digestion and Ficoll density centrifugation of the pancreas. Four groups of animals were studied: C3H to P2 (group 1), C3H to P0 (group 2), lpr to P0 (group 3), and syngeneic P2 to P2 (group 4). Graft survival monitored by blood sugar levels was compared among the groups. At the time of rejection (blood sugar >300 mg/100 ml), grafts were harvested and analyzed by histopathology, immunocytochemistry, and reverse transcriptase-polymerase chain reaction. Primary splenic T cells of the recipients, harvested at the time of rejection, were tested for cytotoxicity against 51Cr-labeled donor cells.

RESULTS

The mean graft survival for groups 1, 2, and 3 was 10.2+/-1.4, 12.2+/-6.0, and 13.2+/-0.8 days, respectively. Syngeneic grafts survived indefinitely. Rejecting grafts from all groups (1, 2, and 3) showed an intense infiltration by both CD4+ and CD8+ cells and complete islet destruction. Reverse transcriptase-polymerase chain reaction revealed granzyme B in rejecting grafts from all three groups.

CONCLUSIONS

Perforin and Fas pathways alone or in combination are not required for islet rejection, suggesting that these pathways may not play a crucial role in allograft rejection.

Knowledge, Attitude And Practice Of Hypercholesterolemic Type 2 Diabetic Subjects On Dyslipidemia

This study was undertaken to assess the knowledge, attitude and practice (KAP) of hypercholesterolemic type 2 diabetic subjects on dyslipidemia and to analyze the influence of some demographic and socioeconomic factors on the level of KAP.It was a descriptive cross-sectional survey. One hundred eleven newly diagnosed type 2 diabetic subjects (male 61%, female 39%, age 45±9 years, BMI 24±4.8 Kg/m2) with hypercholesterolemia (fasting plasma total cholesterol >200 mg/dl) were selected from the out patient department of BIRDEM by purposive sampling method. Data were collected by a pre-designed, pretested, interviewer-administered questionnaire. Three categories were defined on the basis of the score obtained by each subject namely low, medium and high as follows: knowledge-score <50%, 50-60% and >60%; attitude-score <60%, 60-80% and >80%; and practice-score <50%, 50-70% and >70% respectively. The levels of knowledge were low in 42%, medium in 35% and high in 23% of the study subjects. The corresponding attitude levels were low in 1%, medium in 31% and high in 68%, and the levels of practice were low in 80%, medium in 14% and high in 6% of the subjects. The knowledge score was higher in secondary and graduate (53.4±8.9%, and 54.9±10.1%) groups compared to illiterate-primary group (48.9±9.9%). Practice score of illiterate-primary group (34.5±16.8%) was lower than secondary and graduate (43.1±13.9% and 46.7±18.1%) groups, but they did not differ on attitude. The various income groups did not differ on knowledge. Attitude score of high-income group (78.7±8.4%) was better than low-income group (70.9±11.8%). Practice score in high-income group (44.7±16.0%) was better than medium income and low-income groups (31.3±14.5% and 28.6±15.0%). Knowledge and practice score in Bangladeshi hypercholesterolemic type 2 diabetic subjects are not satisfactory although they have fairly good attitude levels. Education and income status are the major determinants of knowledge, attitude and practice regarding dyslipidemia in diabetes. A coordinated policy is required to promote knowledge and attitude on healthy lifestyle and to translate those into practice.DOI: http://dx.doi.org/10.3329/imcj.v5i2.10096 IMCJ 2011; 5(2): 37-41
