To survey risk factors in coronary heart disease, we compared serum fatty acid composition and lipids for university students in Japan (33 males and 29 females) and in the Netherlands (20 males and 19 females). No significant differences were found between the mean levels of cholesterol (Chol) and triglycerides (TG) between the subjects in the two countries. The mean levels of polyunsaturated fatty acid (PUFA), monounsaturated fatty acid (MUFA) and saturated fatty acid (SFA) of Japanese students were similar to those of the Dutch students. In both countries, the levels of Chol showed a positive correlation with the levels of PUFA, n−6 PUFA, linoleic acid (C18: 2n−6), and arachidonic acid (AA, C20: 4n−6) but no correlation with the percentages of PUFA and the ratio of PUFA/SFA. On the other hand, the TG levels correlated inversely with the percentage of PUFA and the ratios of PUFA/SFA in both countries. When compared to those of Japanese students, low eicosapentaenoic acid (EPA, C20: 5n−3) and high AA were found in the Dutch students (p < 0.001, respectively). The total amounts of n−3 PUFA in the Dutch were significantly lower than those in the Japanese (p < 0.001) but no differences among those of n−6 PUFA. The ratios of EPA/AA and n−3/n−6 PUFA of the Dutch students were lower than those of the Japanese students (p < 0.001, respectively). The ratio of EPA/AA showed a positive correlation with EPA but not with AA in both countries. The levels of Toc which will decrease the risk of coronary vascular disease (CVD) were lower in Japan than those in the Dutch in both sexes (p < 0.01, respectively). These results suggest that the low EPA and high AA levels and the low n−3/n−6 PUFA ratio may lead to greater incidence of CVD.

The physical status and serum mineral concentrations for people aged 10 to 68 years living in an agricultural southern region of Nepal were determined. Systolic (SBP) and diastolic blood pressure (DBP) for both sexes in the 10−14 year age group were low (p<0.05, vs the other age groups) and those for the over 50−year−olds tended to be higher than the other age groups. The mean values of total proteins (TP) (8.6±0.5 g/dl for males and 8.7±0.6 g/dl for females) were high due to an increase of globulin (3.9±0.4 g/dl for males and 4.1±0.5 g/dl for females). More than three−fourths of the subjects of both sexes showed calcium (Ca) levels of 9.0−11.2 mg/dl and about 65% of them showed potassium (K) Ievels of 4.8−5.4 mEq/l. A significant positive correlation between DBP and serum K was observed (p<0.05). Serum inorganic phosphorus (IP) correlated with age (p<0.001) and body mass index (BMI) (p<0.001). The serum Ca levels correlated with TP (r=0.31, p<0.001), albumin (Alb) (r=0.50, p<0.001), IP (r=0.31, p<0.001), K (r=0.32, p<0.001) and chlorine (Cl)(r=−0.37, p<0.001). Cl was associated with TP (r=−0.21, p<0.05), Alb (r=−0.36, p<0.001) and IP (r= −0.21, p<0.05). These results suggested that Ca intake for the subjects seemed to be insufficient although their serum Ca level was within normal.

OBJECTIVEThis study examined the levels of serum protein fractionation, immunoglobulin (Ig) and antistreptolysin O (ASO) of people (91 males and 84 females aged 10-68 years) living in the Terai region of southern Nepal, as there has previously been no information available about them.

METHODSBlood samples were collected early in the morning after overnight fasting. Serum protein fractionation was carried out by cellulose-acetate electrophoresis. IgG, IgA, IgM and ASO were measured by immuno-turbidimetry with clinical kits.

RESULTSThe mean proportion of albumin (Alb) was rather low due to increased globulin (Glb). The Alb level of males was significantly higher than that of females, while the male γ-Glb level was significantly lower than that of females. The mean values of IgG, IgM and ASO for males were lower than those values for females, although the difference was significant only for the IgM value. The mean values of IgM for female age groups of 30-39 years or less were significantly higher than those for the corresponding male age groups. Age correlated positively with IgA, and negatively with ASO in both sexes. γ-Glb and IgG correlated significantly with TP, AlB, α(1)-Glb and IgA in both sexes. ASO correlated with β-Glb and IgA in males, and with γ-Glb and IgG in females.

CONCLUSIONSThe fact that the level of γ-Glb, a major component of serum globulin, was high suggested exposure to a highly bacterial and viral environment. These results point to the need to prevent infectious diseases as well as improve their nutritional status, especially for children and young adults.

OBJECTIVEThe food consumption and serum nutritional status of people living in the Kathmandu valley, Nepal, were examined to obtain actual data for comparison with our previous findings.

METHODSA dietary survey of 45 males and 60 females was carried out in March 1997 by the 24-hr dietary recall method and nutrient intake was calculated from food tables of India and Japan. Fasting venous blood samples were obtained and serum biochemical parameters were measured using clinical kits.

RESULTSThe mean body mass index values was at about the same level in both sexes, although the mean percentage body fat of females was higher than that of males, and vice versa for packed red cell volume. The main foods consumed by both sexes, were rice, potatoes, meats, milk & dairy products and vegetables, with a difference in the amounts consumed. Females did not drink alcoholic beverages. The mean daily intakes of energy, protein, lipids, iron and vitamin B group for the males were higher than those for the females, while those of vitamins A and C for the males were lower than those for the females. The mean values of serum biochemical parameters for both sexes were generally at the normal levels, but those of ALT and TG were at the higher end of the normal range. Differences of correlation between food groups and between serum parameters were observed depending on the sex, however, no clear relationship between food and nutrient intake and serum biochemical parameters were observed.

CONCLUSIONSThe present food intake study revealed that the amounts of food consumption for both sexes, especially for the females, were mostly insufficient although the serum parameters were at the normal levels. The energy intake of both sexes was lower than that of estimated requirements and those in Terai region. The relatively high serum TG level of the subjects may be due to the consumption of large amounts of cereals containing much carbohydrate. Our findings suggested a marked influence on food consumption by food price and income in spite of the easier food availability in the city, and also lack of knowledge about nutrients and health, thus there is need for improvement of the nutritional status of this group of people.

OBJECTIVEThe present study examined the levels of serum α-Tocopherol (Toc), retinol (Ret), cholesterol (Chol) and triglycerides (TG), and their correlations in the sera of people in Nepal.

METHODSThe survey was conducted on the general populace in the agricultural Terai region in southern Nepal. The study population consisted of 93 males and 83 females aged 10-68 years. Serum Toc and Ret were measured by high-performance liquid chromatography.

RESULTSNo significant differences were observed between the genders for the average of total Chol (T-Chol) (140 and 145 mg/100 ml, respectively), HDL-C (45 and 47 mg/100 ml), LDL-C (94 and 97 mg/100 ml), and TG (106 and 110 mg/100 ml), and the ratio of LDL/HDL (2.16). The levels of mean Toc (4.32 and 4.27 μg/ml) were about the same for both genders, while the mean Ret levels were significantly higher for males (624 ng/ml) than for females (535 ng/ml) (p<0.001). A direct relationship was found between the levels of Toc and Ret (r=0.46, p<0.001 and r=0.28, p<0.05 for males and females, respectively). Serum levels of Toc and Ret were positively related to the levels of Chol (r=0.48 and r=0.58, p<0.001 for males and r=0.49, p<0.01 and r-0.28, p<0.05 for females, respectively). The ratio of Toc/TG normalized to serum TG was directly correlated to the ratio of Ret/TG (r=0.79 for males, and r=0.72 for females, p<0.001, respectively) and the ratios of Toc/TG and Ret/TG were negatively related to the LDL/HDL levels (r=-0.49 and r=-0.43, for males, and r=-0.46 and r=-0.57 for females, p<0.001, respectively).

CONCLUSIONThe levels of Toc and Ret were low in the sera of people living in the southern rural Terai region in Nepal, and it was found that lower levels of Toc and Ret normalized to TG increased the ratio of LDL/HDL. These results suggest that greater intake of foods rich in Toc and Ret should be encouraged to reduce the erisk of coronary heart disease.
