Prevalence of diabetes in various habitats of West Bengal, India

The epidemiological profile data were collected for diabetes mellitus from the people living in three habitats (rural, industrial and urban) having considerable difference in their lifestyle and socio-economic status. Every 5th (occasionally 4th or 6th) member from each habitat was sampled; no restriction regarding age was kept during screening; OGTT (oral glucose tolerence test) was performed 2 hours after 75 g glucose, in those whose FBS (fasting blood sugar) was >90 mg/dl. Diagnosis of diabetes mellitus was ascertained, if the FBS was >120 mg/dl and/ or postglucose value was >200mg/dl. The per cent prevalence (among all aged people) of diabetes mellitus in rural, industrial and urban habitats were found to be: 1.66 +/- 0.58 (male 1.99 +/- 0.88, female 1.3 +/- 0.75); 3.00 +/- 0.74 (male 3.17 +/- 1.04, female 2.80 +/- 1.04) and 4.8 +/- 0.98 (male 5.31 +/- 1.43, female 4.27 +/- 1.32) respectively.     

Relationship between iron deficiency anaemia and serum lipid levels in Indian adults

Both iron deficiency anaemia and dyslipidaemia are widely prevalent public health problems, especially in the Indian population. Some link has been suggested between the two potentially morbid conditions but a sufficient Indian study could not be found in this regard. This study was planned to find the changes in serum lipid profile in adult Indian patients with iron deficiency anaemia and the effect of oral iron therapy on them. Seventy patients with iron deficiency anaemia and 70 age and sex matched healthy controls, in the age group of 18-35 years were investigated for any possible changes in serum lipid profile ie, triglycerides, total cholesterol, high density lipoprotein cholesterol, very low density lipoprotein cholesterol and low density lipoprotein cholesterol. The patients were followed up after 3 months of oral iron therapy. The results are shown as mean +/- standard deviation. Triglycerides and very low density lipoprotein cholesterol levels were found to be significantly (p < 0.001) elevated in the iron deficiency anaemia group (151.87 +/- 48.06 mg/dl and 30.40 +/- 9.71 mg/dl) as compared to controls (109.99 +/- 30.81 mg/dl and 21.96 +/- 6.69 mg/dl), whereas levels of low density lipoprotein cholesterol were found to be significantly (p = 0.02) lower in patients (90.96 +/- 41.55 mg/dl) as compared to controls (105.24 +/- 26.45 mg/dl). However, after treatment (in 43 patients) there was significant (p < 0.001) reduction in the levels of triglycerides and very low density lipoprotein cholesterol (111.56 +/- 26.87 mg/dl and 22.30 +/- 5.36 mg/dl) when compared to their pretreatment levels (154.70 +/- 53.89 mg/dl and 30.93 +/- 10.84 mg/dl), whereas low density lipoprotein cholesterol levels did not show any significant change. These findings indicate that iron deficiency anaemia in Indian adults is attended by abnormal serum lipid profile, which responds significantly to iron therapy.     

Comparative evaluation of the efficacy, safety, and tolerability of rosuvastatin 10 mg with atorvastatin 10 mg in adult patients with hypercholesterolaemia: the first Indian study

To compare the efficacy, safety and tolerability of rosuvastatin 10mg with atorvastatin 10 mg in adult Indian patients with hypercholesterolaemia, a prospective, open-label, comparative, phase III study was conducted. A total of 45 patients of either sex, between 18 and 80 years of age with hypercholesterolaemia, having LDL cholesterol (LDL-C) of 160 and < 250 mg/dl and triglyceride < 400 mg/dl, were included in this trial. After a dietary run-in period of 2 weeks, patients received either rosuvastatin 10 mg once daily or atorvastatin 10 mg once daily, for 6 weeks. The fall in the mean LDL-C levels after 6 weeks of treatment in rosuvastatin group (40.1%) was significantly more as compared to the fall in atorvastatin group (29.8%). Other secondary lipid parameters like total cholesterol (TC), HDL cholesterol (HDL-C), triglycerides, apo-B, apo-AI, and TC/HDL-C ratio also showed more beneficial changes from the baseline in rosuvastatin group than in atorvastatin group. Rosuvastatin 10 mg shows significantly better efficacy than atorvastatin 10 mg in reducing LDL-C levels and produces greater improvements in other elements of the lipid profile.     

Plasma lipoprotein levels and the prevalence of hyperlipoproteinemia in a Canadian working population

The lipids and lipoproteins — cholesterol (C), triglyceride (TG) and high-density, low-density, very-low-density and sinking pre-β-lipoprotein cholesterol (HDL-C, LDL-C, VLDL-C and SPB-C) — in plasma samples from 1620 fasting white adults and children from the Toronto—Hamilton area were analysed. The mean concentration of HDL-C was about 45 mg/dl in men and about 60 mg/dl in women, and the levels were constant throughout adult life in both sexes. Boys had higher mean HDL-C levels than men, but girls had lower mean HDL-C levels than women. Mean LDL-C levels, like total C levels, increased with age, from about 87 mg/dl in boys to 136 mg/dl in men, and from about 91 mg/dl in girls to 145 mg/dl in women. The mean levels of VLDL-C followed the TG patterns for age and sex, rising from about 7 mg/dl in boys to 26 mg/dl in men, and from about 11 mg/dl in girls to 19 mg/dl in women. SPB-C was detectable visually in 39% of the population and with the aid of densitometry in 54%; the levels were not related to age, sex or oral contraceptive use, and the median level was 3 mg/dl.

Prevalence estimates of hyperlipoproteinemia showed that type IV was the most common, and it was found more than three times as often in men as in women. This was in part due to the customary use of plasma TG cut-off points that do not reflect the large difference in TG levels between males and females. Type IIA hyperlipoproteinemia was found in about 2% of the adults and type IIb in a further 1%. Types I, III and V were all rare. The prevalence of types II and IV hyperlipoproteinemia was four times greater in women using oral contraceptives than in nonusers in the same age range.

     

Prevalence of diabetes, hypertension and obesity at different levels of urbanisation in Vanuatu

OBJECTIVE: To determine the prevalence of non-communicable disease, specifically hypertension, diabetes and obesity, amongst populations at different levels of urbanisation in Vanuatu, and to relate the frequency of these conditions to the modernisation of way of life. DESIGN: A cross-sectional population-based comparative study of indicative cluster samples. SETTING: Republic of Vanuatu (south-west Pacific). A relatively undeveloped malarious island country. PARTICIPANTS: Adult (aged greater than or equal to 20 years) Melanesian ni-Vanuatu of both sexes. An occupation-based (civil servants) urban sample (n = 623) and area-based semi-rural (n = 349) and rural (n = 397) samples were employed. Response rates were 78%-92%. INTERVENTIONS: Cases detected were referred for assessment and treatment by local medical staff. MAIN OUTCOME MEASURES: Body mass index, triceps skinfold thickness, blood pressure, plasma glucose (fasting and 2 hours after 75 g glucose), plasma cholesterol and triglyceride levels. RESULTS: Modernity scores confirmed that the three locations represented different levels of acculturation. Prevalences of non-communicable disease were relatively low compared to other Pacific Island communities and industrialised countries. These conditions were nevertheless more common in the urban sample and least common in the rural sample. Non-communicable disease correlated positively with modernity scores and negatively with physical activity scores. Obesity correlated with blood pressure in the urban sample, and there was indirect evidence (urine sodium concentration) of higher salt intake with modernisation. Mean plasma cholesterol levels were lowest in the rural group. CONCLUSIONS: Prevalences of non-communicable disease are relatively low in Vanuatu, although rural-urban differentials are present, and likely to increase with continued development. The evidence presented is consistent with non-communicable disease being related to the modernisation of way of life; specifically: decreased exercise, obesity, and dietary change. Preventive activities should commence now.     

Lipid levels among African and Middle-Eastern Bedouin populations.

BACKGROUND: Previous studies observed higher high-density lipoprotein (HDL) levels and lower triglycerides levels among people of African ancestry. The goal of this study was to characterize lipid levels in Bedouins of African vs. Middle-Eastern ethnicity. MATERIAL/METHODS: A cross-sectional study was conducted in a Bedouin primary care clinic in southern Israel, with 4470 listed individuals over the age of 21, of whom 402 (9%) were of African origin. A stratified random sample was included in the analysis. Associations between ethnicity, age, gender and lipid levels were assessed. Multiple linear regression and logistic regression models were used for multivariate analysis. RESULTS: The study included 261 African Bedouins and 406 Middle-Eastern Bedouins. (median age: 37 years, 58.6% females). The average total cholesterol and low-density lipoprotein (LDL) levels were 10 mg/dl lower among African Bedouins as compared to Middle-Eastern Bedouins (total cholesterol: 168.6 vs. 179.6 mg/dl, p<0.001; LDL: 99.5 vs. 109.0 mg/dl, respectively, p<0.001). Average triglycerides levels were 36 mg/dl lower among African Bedouins as compared to Middle-Eastern Bedouins (102.8 vs. 138.9 mg/dl, respectively, p<0.001). Average HDL levels were 3 mg/dl higher among African Bedouins as compared to Middle-Eastern Bedouins (48.3 vs. 44.6 mg/dl, respectively, p<0.001). CONCLUSIONS: A lower prevalence of dyslipidemia was found in African Bedouins, as compared with Middle-Eastern Bedouins.

LIPID PROFILE IN NORMAL HEALTHY CHILDREN

One hundred and fifty healthy children in the age group of 0–12 years were studied to establish normal levels of lipid profile. They were divided into six equal groups viz., newborns, 0–1 year, 1–4 years, 4–7 years, 7–10 years and 10–12 years. The mean values ± SD for total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides were 70 ± 14.48 mg/dl, 35.1 ± 8.04 mg/dl, 23.8 ± 10.62 mg/dl and 50.9 ± 20.77 mg/dl respectively for male neonates and 71.8 ± 13.96 mg/dl, 34.6 ± 6.55 mg/dl, 25.5 ± 9.29 mg/dl and 57.2 ± 18.57 mg/dl respectively for female neonates. These values increased to 158.7 ± 21.23 mg/dl, 60.7 ± 11.70 mg/dl, 80.3 ± 19.26 mg/dl, 86.7 ± 28.80 mg/dl in males and 161.6 ± 23.09 mg/dl 66.7 ± 8.75 mg/dl, 75.8 ± 20.26 mg/dl and 93.2 ± 44.09 mg/dl in females respectively between 10–12 years of age, The various lipid fractions were at the lowest level at birth and increased significantly during first year of life, there after showing a much slower rise in levels. There was no significant difference in values between male and female children.KEY WORDS: Lipid profile, Total cholesterol, HDL cholesterol, LDL cholesterol, Triglycerides
