Nutritional status and mortality of highland children in Nepal: Impact of sociocultural factors

This study investigates the nutritional status of native children in the highlands of Nepal (1,700–3,000 m) and explores the relationship between child mortality and surviving children's nutritional status. A random sample of 145 households from 11 villages in the Koshi Hill Zone in east Nepal was surveyed, and the nutritional status of the 438 children <14 years of age living in these households was assessed by means of anthropometry. We found a severe growth retardation in the Nepalese children compared to lowland reference groups as well as to highland children from the Andes. Child mortality and altitude are not significantly different between higher (Brahman and Chetri) and lower (Baisya and Sudra) caste households. A lower caste status and higher altitude of the household is associated with a significantly better nutritional status in offspring. In multiple regression analyses, improved nutritional status in children is significantly associated with lower caste (P = 0.001), higher altitude (P = 0.009), and less crowding (P = 0.001) but not with sibling mortality (P = 0.11). We thus conclude that nutritional status of children in households in the highlands of Nepal is associated with the household's socioeconomic status and altitude but not with mortality among siblings. © 1996 Wiley-Liss, Inc.     

Açaí palm management disturbs seed rain and soil seed bank of an Amazonian estuarine forest

The exploitation of non-timber forest products has been proposed as a sustainable way to exploit tropical forests, but such an opportunity remains to be proved. Here, we examine the impact of intensive açaí palm (Euterpe oleracea) management on the seed rain and soil seed bank in an estuarine forest landscape with a long history of forest management by locals in the Amazon region. Seed rain (100 80 cm² collectors) and soil seed bank (100 30 cm² samples) were monitored through a year across 20 forest stands, covering a gradient of açaí stem density (50–3575 açaí stems per ha). Seed rain and bank were dominated by açaí seeds (85.5%–85.8%) and by excluding them, seed rain and bank were low density and species poor, capturing a tiny subset from the local (17.91%–19.40%) and landscape woody flora (11.82%–14.55%). Moreover, autochthonous and vertebrated-dispersed predominated as well as those from tree species considered useful by locals. Overall, açaí stem density positively affected açaí seed abundance in the seed rain and negatively affected seed pools in the bank in relation to abundance of seeds and vertebrated dispersed, while adult tree species richness and density and accessibility to forest stands were associated with more diversified seed pools. Thereby, forest stands are exposed to different levels of açaí management (high vs. low intensity) supported taxonomically distinct seed pools. Our results suggest that açaí intensification disturbs seed rain and soil seed bank with potential impacts on forest regeneration and the forest integrity standards required to consider açaí fruit production as sustainable according to current legislation.     

A comparison of the nutritional status and food security of drug-using and non-drug-using Hispanic women in Hartford,Connecticut

This study compared food insecurity, nutritional status (as measured through anthropometry and dietary intake), and food preparation patterns of low-income Puerto Rican female out-of-treatment drug users with that of low-income Puerto Rican women who reported no drug use. A convenience sample of 41 drug users was compared with 41 age-matched non-drug-users from inner-city Hartford, Connecticut. A culturally appropriate food frequency questionnaire was administered and anthropometric measurements were taken. The findings suggest a high degree of poverty among all study participants, but in particular among drug users. Drug users were more likely than the controls to be food insecure (P < 0.05) and to be exposed to increasingly severe food sufficiency problems. The daily frequency of consumption of vegetables was lower (P = 0.03) for drug users than non-drug-users. Conversely, the frequency of consumption for sweets/ desserts was significantly higher for drug users than the controls (P = 0.0001). Drug users, who were classified as food insecure were less likely to consume vegetables (P = 0.004) and fish (P = 0.03) than were controls who were food insecure. When comparing drug users with controls, the former group reported consuming fewer meals during a usual week than the latter group (P < 0.0001). Drug users were more likely to fry foods (P = 0.02) while the controls were more likely to bake (P = 0.005), boil (P = 0.02), and steam (P = 0.002) foods. All anthropometric measurements, except for height, were significantly lower for drug users. The results show that drug users generally maintain poorer nutritional status than non-drug-users. Nutrition interventions as part of drug treatment are needed. Am J Phys Anthropol 107:351–361, 1998. © 1998 Wiley-Liss, Inc.     

Associations between height,body mass,and frequency of decayed,extracted, and filled deciduous teeth among two cohorts of Taiwanese first graders

In this study, heights, weights, and numbers of decayed, extracted, and filled (DEF) deciduous teeth of 300 first‐graders from a less affluent area of Taipei were compared with those of 277 first‐graders from a more affluent one. Parents of all children self‐identified as having ancestors from Fujian. This study tested the hypothesis that synergisms between under‐nutrition and disease form part of a causal pathway contributing to the risk of deciduous caries. Within the less affluent community significant inverse associations between height and body mass index, as proxies for nutritional status, and the frequency of DEF deciduous teeth were anticipated. These associations were not expected in the more affluent community where nutritional status was adequate. An alternative hypothesis, that parental behavior potentially correlated with parental education, occupational backgrounds, housing, or family size contributed independently to offspring nutritional status and caries risk, was evaluated with available data. Consistent with the primary hypothesis, regression analyses revealed significant negative slopes of height (P = 0.002) and log BMI (P = 0.036) on total DEF deciduous teeth in the less affluent group, but not in the more affluent one. Direct tests of slope coefficients in the two groups indicate a significant difference for height (P = 0.041) but not log BMI (P = 0.29). Inclusion of parental education, occupational categories, housing, and numbers of siblings in the regression model provided no support to the alternative hypothesis. Results suggest that improving nutritional status significantly lowers caries risk, though most variation is probably attributable to other factors.

Circulating IL-6 concentrations and abdominal adipocyte isoproterenol-stimulated lipolysis in women

Objective: To examine the association of plasma interleukin‐6 (IL‐6) concentrations with adiposity and fat cell metabolism in women. Methods and Procedures: Omental (OM) and subcutaneous (SC) adipose tissue samples were obtained from 48 healthy women (age: 47 ± 5 years, BMI: 26.9 ± 5.3 kg/m²) undergoing gynecological surgeries. Total and visceral adiposity were assessed by dual‐energy X‐ray absorptiometry and computed tomography, respectively. Measures of adipocyte lipolysis (basal, isoproterenol‐, forskolin‐, and cyclic dibutyryl‐adenosine monophosphate (AMP)‐stimulated) and adipose tissue lipoprotein lipase (LPL) activity were obtained. Plasma IL‐6 was measured by radioimmunoassay. Results: Plasma IL‐6 was positively correlated with total body fat mass (r = 0.32, P < 0.05), SC adipose tissue area (r = 0.35, P < 0.05), SC adipocyte diameter (r = 0.30, P < 0.05), and a trend was observed with visceral adipose tissue area (r = 0.20, P < 0.07). Plasma IL‐6 was positively correlated with glycerol released in response to isoproterenol (10^?5 to 10^?8 mol/l) by isolated SC (0.31 ≤ r ≤ 0.65, P < 0.05) and OM (0.36 ≤ r ≤ 0.40, P < 0.02) adipocytes, independent of menopausal status. No correlation was found with LPL activity. A subsample of women with high plasma IL‐6 (n = 10) was matched with women with low plasma IL‐6 (n = 10) for total body fat mass. OM adipocyte glycerol release in response to isoproterenol (10^?5 to 10^?8 mol/l) was higher in the subsample of women with elevated plasma IL‐6 (P ≤ 0.07). Discussion: We observed that OM lipolysis was significantly higher in women with elevated plasma IL‐6 for a similar body fat mass and menopausal status. These results suggest that higher circulating IL‐6 concentrations are associated with increased isoproterenol‐stimulated lipolysis especially in OM abdominal adipocytes in women.     

Nutritional consequences of the transformation from subsistence to commercial agriculture in Tabasco,Mexico

Recent changes in the area of the Plan Chontalpa in Tabasco have greatly reduced the production of subsistence crops by rural families, resulting in decreased crop diversity and a concomitant increase in the degree of dependence on outside sources of food. Results from a nutrition survey of 149 families demonstrate that dietary diversity, dietary quality, and nutritional status of preschool children are negatively associated with lower crop diversity and increased dependence on purchased foods. Dietary deterioration is illustrated by the negative relationship found between nutritional status and increased sugar consumption. The assumption that a rise in income accompanying the adoption of commercial production will automatically lead to improved nutrition is challenged: income levels were not found to be consistently related to nutritional status. Children of families that have converted to cattle production, despite greater land availability and family incomes, do not have improved nutritional status. In the study area, where wages are low and food prices are very high, the value of a higher degree of self-sufficiency in food is recognized, yet families continue to switch to cash crops due to the environmental, economic, and time constraints imposed by the system of commercial agriculture in which they participate. The solution is not to return to traditional subsistence farming, however, but to determine under what conditions a more progressive form of agricultural change can occur.     

Impact of tooth replacement strategies on the nutritional status of partially-dentate elders

doi: 10.1111/j.1741‐2358.2011.00579.x
Impact of tooth replacement strategies on the nutritional status of partially‐dentate elders Objective: To investigate the impact of tooth replacement on the nutritional status of partially dentate older patients, and, to compare two different tooth replacement strategies; conventional treatment using removable partial dentures and functionally orientated treatment based on the shortened dental arch. Background: Amongst older patients, diet plays a key role in disease prevention, as poor diets have been linked to numerous illnesses. Poor oral health and loss of teeth can have very significant negative effects on dietary intake and nutritional status for elderly patients. There is evidence that good oral health generally, has positive effects on the nutritional intake of older adults. Materials and methods: A randomised, controlled clinical trial was designed to investigate the impact of tooth replacement on the nutritional status of partially dentate elders. Forty‐four patients aged over 65 years completed the trial, with 21 allocated to conventional treatment and 23 allocated to functionally orientated treatment. Nutritional status was accessed at baseline and after treatment using the Mini Nutritional Assessment (MNA) and a range of haematological markers. Results: At baseline, relationships were observed between the number of occluding tooth contacts and some measures of nutritional status. As the number of contacts increased, MNA scores (R = 0.16), in addition to vitamin B12 (R = 0.21), serum folate (R = 0.32) and total lymphocyte count (R = 0.35), also increased. After treatment intervention, the only measure of nutritional status that showed a statistically significant improvement for both treatment groups was MNA score (p = 0.03). No significant between group differences were observed from analysis of the haematological data. Conclusion: In this study, prosthodontic rehabilitation with both conventional treatment and functionally orientated treatment resulted in an improvement in MNA score. Haematological markers did not illustrate a clear picture of improvement in nutritional status for either treatment group.     

Serum concentrations of insulin‐like growth factor‐i and insulin‐like growth factor binding protein‐2 and ‐3 in eight hoofstock species

The somatotropic axis, which includes growth hormone, insulin‐like growth factor (IGF)‐I, and IGF binding proteins (IGFBP), is involved in the regulation of growth and metabolism. Measures of the somatotropic axis can be predictive of nutritional status and growth rate that can be utilized to identify nutritional status of individual animals. Before the somatotropic axis can be a predictive tool, concentrations of hormones of the somatotropic axis need to be established in healthy individuals. To begin to establish these data, we quantified IGF‐I, IGFBP‐2, and IGFBP‐3 in males and females of eight threatened hoofstock species at various ages. Opportunistic blood samples were collected from Bos javanicus (Java banteng), Tragelaphus eurycerus isaaci (bongo), Gazella dama ruficollis (addra gazelle), Taurotragus derbianus gigas (giant eland), Kobus megaceros (Nile lechwe), Hippotragus equines cottoni (roan antelope), Ceratotherium simum simum (white rhinoceros), and Elephas maximus (Asian elephant). Serum IGF‐I and IGFBPs were determined by radioimmunoassay and ligand blot, respectively. Generally, IGF‐I and IGFBP‐3 were greater in males, and IGFBP‐2 was greater in females. In banteng (P = 0.08) and male Nile lechwe (P<0.05), IGF‐I increased with age, but decreased in rhinoceros (P = 0.07) and female Nile lechwe (P<0.05). In banteng, IGFBP‐3 was greater (P<0.01) in males. In elephants (P<0.05) and antelope (P = 0.08), IGFBP‐2 were greater in females. Determination of concentrations of hormones in the somatotropic axis in healthy animals makes it possible to develop models that can identify the nutritional status of these threatened hoofstock species.

Nominal association with CHRNA4 variants and nicotine dependence

Nicotine binds to nicotinic acetylcholine receptors and studies in animal models have shown that α4β2 receptors mediate many behavioral effects of nicotine. Human genetics studies have provided support that variation in the gene that codes for the α4 subunit influences nicotine dependence (ND), but the evidence for the involvement of the β2 subunit gene is less convincing. In this study, we examined the genetic association between variation in the genes that code for the α4 (CHRNA4) and β2 (CHRNB2) subunits of the nicotinic acetylcholine receptor and a quantitative measure of lifetime DSM‐IV ND symptom counts. We performed this analysis in two longitudinal family‐based studies focused on adolescent antisocial drug abuse: the Center on Antisocial Drug Dependence (CADD, N = 313 families) and Genetics of Antisocial Drug Dependence (GADD, N = 111 families). Family‐based association tests were used to examine associations between 14 single nucleotide polymorphisms (SNPs) in CHRNA4 and CHRNB2 and ND symptoms. Symptom counts were corrected for age, sex and clinical status prior to the association analysis. Results, when the samples were combined, provided modest evidence that SNPs in CHRNA4 are associated with ND. The minor allele at both rs1044394 (A; Z = 1.988, P = 0.047, unadjusted P‐value) and rs1044396 (G; Z = 2.398, P = 0.017, unadjusted P‐value) was associated with increased risk of ND symptoms. These data provide suggestive evidence that variation in the α4 subunit of the nicotinic acetylcholine receptor may influence ND liability.     

Increases in body mass index during infliximab therapy in patients with Crohn's disease: an open label prospective study

In the past, the impact of infliximab therapy on nutritional status in patients with Crohn’s disease (CD) has not been assessed. This prospective study was to investigate the effect of infliximab on nutritional status in CD patients. Fifty consecutive patients with active CD received infliximab (5 mg/kg) at weeks 0, 2 and 6 as remission induction therapy, and then at 8 weeks intervals as maintenance therapy. Patients were followed for 60 weeks. CD activity index (CDAI) and body mass index (BMI) were monitored. A fall in CDAI by ?70 was defined as response to therapy, while CDAI <150 meant clinical remission. At week 10, 39 patients (78%) responded to infliximab induction therapy. BMI significantly increased during these 10 weeks (P < 0.0001). The mean increase in BMI was significantly higher in patients who responded to infliximab vs patients who did not (P = 0.03). Further, at weeks 30 and 60, 35 patients (70%) and 33 (66%) were in remission, respectively. The mean increase in BMI was significantly higher in patients who maintained remission vs patients not in remission (week 30, P = 0.02; week 60, P = 0.01). Patients with a low baseline BMI (<18.5) and those with small bowel involvement achieved a higher increase in BMI as compared to patients with BMI ?18.5 or patients without small bowel involvement. In this study, infliximab therapy was associated with improvement of patients’ nutritional status, notably patients who responded to this biologic. Additionally, in patients with malnutrition and small bowel involvement, the nutritional impact of infliximab was higher.     

Preventing Acute Malnutrition among Young Children in Crises: A Prospective Intervention Study in Niger

Background

Finding the most appropriate strategy for the prevention of moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) in young children is essential in countries like Niger with annual “hunger gaps.” Options for large-scale prevention include distribution of supplementary foods, such as fortified-blended foods or lipid-based nutrient supplements (LNSs) with or without household support (cash or food transfer). To date, there has been no direct controlled comparison between these strategies leading to debate concerning their effectiveness. We compared the effectiveness of seven preventive strategies—including distribution of nutritious supplementary foods, with or without additional household support (family food ration or cash transfer), and cash transfer only—on the incidence of SAM and MAM among children aged 6–23 months over a 5-month period, partly overlapping the hunger gap, in Maradi region, Niger. We hypothesized that distributions of supplementary foods would more effectively reduce the incidence of acute malnutrition than distributions of household support by cash transfer.

Methods and Findings

We conducted a prospective intervention study in 48 rural villages located within 15 km of a health center supported by Forum Santé Niger (FORSANI)/Médecins Sans Frontières in Madarounfa. Seven groups of villages (five to 11 villages) were allocated to different strategies of monthly distributions targeting households including at least one child measuring 60 cm–80 cm (at any time during the study period whatever their nutritional status): three groups received high-quantity LNS (HQ-LNS) or medium-quantity LNS (MQ-LNS) or Super Cereal Plus (SC+) with cash (€38/month [US$52/month]); one group received SC+ and family food ration; two groups received HQ-LNS or SC+ only; one group received cash only (€43/month [US$59/month]). Children 60 cm–80 cm of participating households were assessed at each monthly distribution from August to December 2011. Primary endpoints were SAM (weight-for-length Z-score [WLZ]<−3 and/or mid-upper arm circumference [MUAC]<11.5 cm and/or bipedal edema) and MAM (−3≤WLZ<−2 and/or 11.5≤MUAC<12.5 cm). A total of 5,395 children were included in the analysis (615 to 1,054 per group). Incidence of MAM was twice lower in the strategies receiving a food supplement combined with cash compared with the cash-only strategy (cash versus HQ-LNS/cash adjusted hazard ratio [HR] = 2.30, 95% CI 1.60–3.29; cash versus SC+/cash HR = 2.42, 95% CI 1.39–4.21; cash versus MQ-LNS/cash HR = 2.07, 95% CI 1.52–2.83) or with the supplementary food only groups (HQ-LNS versus HQ-LNS/cash HR = 1.84, 95% CI 1.35–2.51; SC+ versus SC+/cash HR = 2.53, 95% CI 1.47–4.35). In addition, the incidence of SAM was three times lower in the SC+/cash group compared with the SC+ only group (SC+ only versus SC+/cash HR = 3.13, 95% CI 1.65–5.94). However, non-quantified differences between groups, may limit the interpretation of the impact of the strategies.

Conclusions

Preventive distributions combining a supplementary food and cash transfer had a better preventive effect on MAM and SAM than strategies relying on cash transfer or supplementary food alone. As a result, distribution of nutritious supplementary foods to young children in conjunction with household support should remain a pillar of emergency nutritional interventions. Additional rigorous research is vital to evaluate the effectiveness of these and other nutritional interventions in diverse settings.

Ecological stress and linear enamel hypoplasia in Cebus

Although it is assumed that monkeys in some environments experience more nutritional or physiological stress than others, little research has been conducted on this topic. This study examines the relationship between linear enamel hypoplasia (LEH) frequency, a physiological indicator of stress, and environmental stressors. To test this relationship, LEH frequencies were calculated for 144 Cebus from 54 locations in Brazil. Habitat, temperature range, and annual rainfall were compared between individuals with and without LEH. The LEH frequency for Cebus from semideciduous forests was significantly higher than that for monkeys from coastal areas, the rainforest, and the savanna (χ² = 9.97, df = 1; P = 0.0016). A significantly higher LEH frequency was also found for monkeys living in environments with the mean annual temperature between 15 and 18°C than for those in environments greater than 18°C (χ² = 7.74, df = 1, P = 0.0054). However, no significant difference was found between LEH frequency and annual rainfall (t = 1.22, P = 0.23) or the average difference in rainfall between the driest and wettest months (t = 0.77, P = 0.44). These results indicate that levels of physiological stress can differ among environments and that habitat and temperature, but not precipitation, may be driving the difference in stress levels among environments.

Maternal Insulin Sensitivity During Pregnancy Predicts Infant Weight Gain and Adiposity at 1 Year of Age

Emerging evidence suggests that fetal environmental exposures impact on future development of obesity. The objectives of this study were to assess the relationships between (i) maternal insulin sensitivity and glucose tolerance status in pregnancy and (ii) early infant weight gain and adiposity in the first year of life. In this prospective cohort study, 301 women underwent oral glucose tolerance testing for assessment of glucose tolerance status and insulin sensitivity (IS_OGTT) in pregnancy. Their infants underwent anthropometric assessment at 12 months of age, including determination of weight gain in the first year of life and sum of skinfold thickness (SFT), a measure of infant adiposity. Infant weight gain and sum of SFT at 12 months did not differ according to maternal glucose tolerance status. On univariate analyses, weight gain from 0 to 12 months and sum of SFT were negatively associated with maternal IS_OGTT during pregnancy. On multiple linear regression analysis, negative independent predictors of weight gain from 0 to 12 months were maternal IS_OGTT during pregnancy (t = ?2.73; P = 0.007), infant female gender (t = ?3.16; P = 0.002), and parental education (t = ?1.98; P = 0.05), whereas white ethnicity was a positive independent predictor (t = 2.68; P = 0.008). Maternal IS_OGTT (t = ?2.7; P = 0.008) and parental education (t = ?2.58; P = 0.01) were independent negative predictors of sum of SFT at 12 months. Independent of maternal glucose tolerance status, maternal insulin resistance during pregnancy is associated with increased infant weight gain and adiposity over the first year of life. Further longitudinal study to evaluate obesity in this group of children will increase our understanding of the contribution of the intrauterine environment to their long‐term health.     

Coupling of growth to nutritional status: The role of novel periphery-to-brain signaling by the CCHa2 peptide in Drosophila melanogaster

ABSTRACT

The coupling of growth to nutritional status is an important adaptive response of living organisms to their environment. For this ability, animals have evolved various strategies, including endocrine systems that respond to changing nutritional conditions. In animals, nutritional information is mostly perceived by peripheral organs, such as the digestive tract and adipose tissues, and is subsequently transmitted to other peripheral organs or the brain, which integrates the incoming signals and orchestrates physiological and behavioral responses. In Drosophila melanogaster, adipose tissue, known as the fat body, functions as an endocrine organ that communicates with the brain. This fat body-brain axis coordinates growth with nutritional status by regulating the secretion of Drosophila insulin-like peptides (Dilps) from the brain. However, the molecular nature of the fat body-brain axis remains to be elucidated. We recently demonstrated that a small peptide, CCHamide-2 (CCHa2), expressed in the fat body and gut, directly stimulates its receptor (CCHa2-R) in the brain, leading to Dilp production. Notably, the expression of CCHa2 is sensitive to the presence of nutrients, particularly sugars. Our results, together with the results of previous studies, show that signaling between peripheral organs and the brain is a conserved strategy that couples nutritional availability to organismal physiology.     

The relationships between oral status, physical and mental health, nutritional status and diet type in elderly Japanese women with dementia

Objectives: To suggest methods for maintaining an adequate nutritional status for elderly patients with dementia by evaluating the relationships between oral status, physical and mental health, and feeding conditions. Background: Feeding difficulties in dementia patients are related to food intake, and failure to eat may be associated with weight loss in long‐term care facilities. The relationship between compromised oral function and diet is still unclear. Materials and methods: A cross‐sectional study of 94 elderly women with dementia (mean age 89.6 ± 5.6 years) from a nursing home was undertaken to investigate their oral, physical and mental and nutritional status. Results: There were significant differences in serum albumin (p = 0.0284), N‐ADL (p = 0.0005), NM scale (p = 0.0004) and HDS‐R (p = 0.0004) between denture wearers and non‐denture wearers. However, there were no significant differences in body mass index between denture wearers and non‐denture wearers. Conclusion: A suitable type of diet and assistance with feeding could maintain the nutritional status of elderly patients with dementia if they are still feeding themselves. The nutritional support team will benefit from the participation of a dentist.     

Proteomic changes associated with the development of açaí (Euterpe oleracea Mart.) seeds

Açaí palm (Euterpe oleracea Mart.) seeds are a rich source of mannans, which can be used to generate bioethanol or be converted to high-value D-mannose, in addition to being a source of polyphenols with beneficial health properties. Here, we present a quantitative proteome dataset of açaí seeds at four stages of development (S1, S2, S3, and S4 stages), in which 2465 high confidence proteins were identified and 524 of them show statistically different abundance profiles during development. Several enzymes involved in the biosynthesis of nucleotide-sugars were quantified, especially those dedicated to the formation of GDP-mannose, which showed an increase in abundance between stages S1 and S3. Our data suggest that linear mannans found abundantly in endosperm cell walls are initially deposited as galactomannans, and during development lose the galactosyl groups. Two isoforms of alpha-galactosidase enzymes showed significantly increased abundances in the S3 and S4 stages. Additionally, we quantified the enzymes participating in the central pathway of flavonoid biosynthesis responsible for the formation of catechin and epicatechin, which are subunits of procyanidins, the main class of polyphenols in the açaí seeds. These proteins showed the same pattern of deposition, in which higher abundances were seen in the S1 and S2 stages.     

Hypertriglyceridemic waist phenotype is associated with decreased insulin sensitivity and incident diabetes in elderly men

Objective: To investigate the association between hypertriglyceridemic waist (HTGW) and insulin sensitivity (assessed by euglycemic clamp method), and the development of diabetes in a longitudinal community‐based cohort of elderly men without diabetes at baseline. Design and Methods: The present cross‐sectional study comprised 1,026, 70‐year‐old men without diabetes. The gold standard euglycaemic–hyperinsulinaemic clamp technique was used. Six‐year follow‐up on diabetes status were available in n = 667. The HTGW phenotype was defined as having waist circumference ≥ 90 cm, and triglycerides ≥ 2 mmol L^?1. The men were stratified into those having normal WC and TG (n = 299), one HTGW component (n = 606), and HTGW (n = 121). Results: The association between insulin sensitivity and one HTGW component as well as HTGW was highly significant (P < 0.001) in the whole sample, as well as in individuals with high/low BMI (stratified at ≥25). In longitudinal analyses, participants with HTGW was associated with a more than fourfold increased risk for diabetes (Odds ratio 4.64, 95% CI 1.61–13.4, P = 0.004) compared to those with normal WC and TG. Conclusion: The present study both confirm and extend previous research suggesting that the HTGW‐phenotype portrays an increased glucometabolic risk, also in lean individuals.     

Grades of undernutrition and socioeconomic status influence cognitive development in school children of Kolkata

Cognitive development of children is influenced by different environmental factors like nutritional and socio‐economic status. The objectives of the present study were to determine the influence of grades of undernutrition and socio‐economic status (SES) on the cognitive development of school children of Kolkata. Five hundred sixty six (566) school children having 5–12 years of age were selected from different schools of Kolkata. The cognitive development was measured by the scores of Raven's colored progressive matrices (RCPM). The chronic and acute nutritional statuses were measured from height‐for‐age (HAZ) and weight‐for‐age (WAZ) Z scores respectively with reference to the values of WHO. SES was determined by updated Kuppuswamy scale. The prevalences of undernutrition in the observed children were 57.95% (according to HAZ) and 52.82% (according to WAZ). The age dependent growth curve of RCPM scores of the observed children remains in between the 10th and 25th centile of British children. The children belonging to superior and intellectual deficit IQ classes were 21.55 and 36.40%, respectively of the total subjects. Most of the subjects belong to lower middle (39.93%) and upper middle (36.40%) class of SES. RCPM scores of school children were gradually decreased with the grades of undernutrition and SES. RCPM scores were significantly correlated with HAZ, WAZ, SES, age, and sex (P < 0.001) and strongly associated with HAZ, SES, age, and sex (P < 0.001, P < 0.05). Present study indicates that cognitive development of school children of Kolkata is influenced by the grade of undernutrition and SES.

Long-Term BMI changes since adolescence and markers of early and advanced subclinical atherosclerosis

Although long‐term weight gain has been associated with cardiovascular risk and intima‐media thickening (IMT), no sufficient data exist on possible associations of such weight changes with more advanced stages of subclinical atherosclerosis. Moreover, the value of self‐reported weight changes, a more practical approach to assess long‐term history in adiposity status, is still a matter of debate. In this longitudinal study, long‐term changes in BMI and overweight status were assessed in 106 healthy young adults (age 40.5 ± 1.1 years, 60 males). These were a subgroup of adolescent school students who had originally been examined in 1983 initially aiming to assess cardiovascular risk factor prevalence. Markers of early (carotid IMT) and advanced (presence of plaques in the carotid and femoral arteries and ankle‐brachial index, ABI) subclinical atherosclerosis were measured in all individuals. By multivariate analysis, among other risk factors, IMT and the presence of plaques were independently determined by BMI change, while a low ABI was also determined by changes in overweight status. An adverse long term adiposity profile change (≥ +4 kg/m² and/or change into overweight/obese status from normal weight since adolescence) incrementally determined a low ABI over current risk factors. Self‐reported and actual BMI changes were correlated (r = 0.587) but their means significantly differed, while the former significantly correlated with IMT only (P = 0.032). In conclusion, an adverse long term adiposity status change was more prominently associated with advanced subclinical atherosclerosis and particularly low ABI. These results also suggest that the utility of self‐reported weight changes may be limited in primary prevention practice.
