Prevalence of metabolic syndrome in an urban population: Tehran Lipid and Glucose Study

Objective: To assess the available data on the prevalence of metabolic syndrome (MS) in Latin-American countries. Design: Systematic review. Searches were carried out in PubMed, ISIWeb, SCielo and Redalyc, using 'metabolic syndrome x' and 'prevalence' as keywords for titles and/or abstracts. Articles selected were cross-sectional studies in Latin-American countries, whose main objective was to study MS and whose study population is described below. MS must be determined using Adult Treatment Panel III criteria. Twelve studies with these criteria were selected, one of which was multi-centric. Setting: Latin America. Subjects: Apparently healthy subjects aged 18-65 years (including young adult, mature adult and elderly populations) of both genders. Results: The general prevalence (weighted mean) of MS in Latin-American countries was 24?9 (range: 18?8-43?3) %. MS was slightly more frequent in women (25?3 %) than in men (23?2 %), and the age group with the highest prevalence of MS consisted of those over 50 years of age. The most frequent components of MS were low HDL cholesterol levels (62?9 %) and abdominal obesity (45?8 %). Similar outcomes were obtained from the multi-centre study on Latin-American populations analysed. Conclusions: The present review brings us closer to an understanding of the prevalence of MS in Latin-American countries. However, it is not possible to know the full scope of the problem, partly because data from some countries are not available, and because the methodological differences among the studies published up to the present limit a joint analysis of their results.

“…Hence, in studies carried out on adult populations of India and Iran, the prevalence rates of MS varied from 33?7 % to 41 % (21)(22)(23) .…”

“…Although obesity and level of physical activity contribute significantly to the frequency of MS, other factors, such as a genetic predisposition, may play a role (Abate, 2000;Thomas et al, 2000;Das, 2002). Studies performed in various ethnic groups have also shown that the frequency of individual components of MS can vary between countries (Ford et al, 2002;Onat and Sansoy, 2002;Azizi et al, 2003;Ramachandran et al, 2003;Chuang et al, 2004;Gupta et al, 2004;Kim et al, 2004;Lee et al, 2004;Duc Son et al, 2005;Enkhmaaa et al, 2005;Thomas et al, 2005).…”

Objective: To determine prevalence of the metabolic syndrome (MS) in a sample representing Turkish population using United States Adult Treatment Panel-3 guidelines. Design: The study included random samples from both urban and rural populations in the seven geographical regions of Turkey. The population for this analysis were 2108 men (1372 in urban and 736 in rural areas) and 2151 women (1423 in urban and 728 in rural areas) with a mean age of 40.9714.9 years (range 20-90). Results: The prevalence of the MS diagnosed using the Adult Treatment Panel III criteria was 33.9% (1442 of 4259) and differed significantly in men (28%) and women (39.6%). The prevalence of syndrome increased with age in men, from 10.7% in subjects aged 20-29 years to 49% in those aged over 70 years. The prevalence increased with age in women, from 9.6% in subjects aged 20-29 years to 74.6% in those aged 60-69 years, and decreased to 68.6% in those over 70 years of age. The prevalence of the syndrome was similar in urban (33.8%) and rural (33.9%) population. We found 26.8, 26.4, 19.3, 10.9 and 3.6% of the population had at least 1, 2, 3, 4 or 5 components, respectively. We found 57.2, 32.3 and 10.6% of the subjects with MS had 3, 4 and 5 components, respectively.

“…The metabolic syndrome is defined as a pattern of metabolic disturbances including central obesity, insulin resistance and hyperglycemia, dyslipidemia and hypertension (Reaven, 1988). A recent study in Tehran showed that the metabolic syndrome is highly prevalent in Tehranian adults, with an estimated prevalence of over 30% in adults (Azizi et al, 2003a), which is higher than those in most developed countries such as USA (Ford et al, 2002). The etiology of this syndrome is largely unknown and variations worldwide have prompted researchers to formulate hypotheses for the natural development of the syndrome.…”

Whole-grain consumption and the metabolic syndrome: a favorable association in Tehranian adults

2004

Background: Although dietary guidelines recommend increased intake of grain products to prevent chronic diseases, epidemiologic data regarding whole-grain intake association with metabolic syndrome are sparse. Objective: To evaluate the relationship between whole-grain intakes, metabolic syndrome and metabolic risk factors in Tehranian adults. Design: Population-based cross-sectional study. Setting: Tehran, the capital of Iran. Subjects: A representative sample of 827 subjects (357 men and 470 women) aged 18-74 y. Methods: Usual dietary intake was assessed using a food frequency questionnaire. The procedure developed by Jacobs et al was used to classify grain products into whole and refined grains. Weight and height were measured according to standard protocols and body mass index was calculated. Fasting blood samples were taken for biochemical measurements and blood pressure was assessed according to standard methods. Hypertriglyceridemia, hypercholestrolemia, high LDL, low HDL and metabolic syndrome were defined according to ATP III guidelines and hypertension based on JNC VI. Diabetes was defined as fasting plasma glucose level of Z126 mg/dl or 2-h postchallenge blood glucose level of Z200 mg/dl. Subjects were categorized based on quartile cut-points of whole-and refined-grain intake. Results: Mean (7s.d.) consumptions of whole and refined grains were 93729 and 201757 g/day, respectively. Both men and women reported higher intakes of refined grain than of whole grains. Compared with subjects in the lower quartile category, those in the upper category of whole-grain intake had lower prevalence of metabolic risk factors. Conversely, those in the higher category of refined-grain intake had higher prevalence of metabolic risk factors, except for diabetes. After controlling for confounders, a significantly decreasing trend was observed for the risk of having hypertriglyceridemia (odds ratios among quartiles: 1.00, 0.89, 0.74, 0.61, respectively), hypertension (1.00, 0.99, 0.93, 0.84) and metabolic syndrome (1.00, 0.84, 0.76, 0.68). Higher consumption of refined grains was associated with higher odds of having hypercholestrolemia
