Heat Exposure, Heat-Related Symptoms and Coping Strategies among Elderly Residents of Urban Slums and Rural Vilages in West Bengal, India
The impact of heat stress among the elderly in India-particularly the elderly poor-has received little or no attention. Consequently, their susceptibility to heat-related illnesses is virtually unknown, as are the strategies they use to avoid, or deal with, the heat. This study examined perceptions of comfort, heat-related symptoms, and coping behaviors of 130 elderly residents of Kolkata slums and 180 elderly residents of rural villages south of…
Using multiple correspondence analysis to identify behaviour patterns associated with overweight and obesity in Vanuatu adults
Objective The present study evaluates the use of multiple correspondence analysis (MCA), a type of exploratory factor analysis designed to reduce the dimensionality of large categorical data sets, in identifying behaviours associated with measures of overweight/obesity in Vanuatu, a rapidly modernizing Pacific Island country. Design Starting with seventy-three true/false questions regarding a variety of behaviours, MCA identified twelve most sign…
Coming to grips with economic development: Variation in adult hand grip strength during health transition in Vanuatu
OBJECTIVES: To determine whether (1) maximal handgrip strength (HGS) is associated with inter-island level of economic development in Vanuatu, (2) how associations between island of residence and HGS are mediated by age, sex, body size/composition, and individual sociodeomographic variation, and (3) whether HGS is predictive of hypertension. MATERIAL AND METHODS: HGS was collected from 833 adult (aged 18 and older) men and women on five islands r…
Ownership of consumer electronics is associated with measures of adiposity during health transition in Vanuatu
OBJECTIVE: The Republic of Vanuatu, like many developing nations, is undergoing a rapid health transition. Our previous study identified several behavioral risk factors for the rising prevalence of obesity. Unexpectedly, daily time spent using television and radio was revealed as a protective factor for obesity in 2007. In this study, we sought to explore associations between ownership of consumer electronics (CE) and measures of adiposity in Van…
Secular change in adult stature associated with modernization in Vanuatu
OBJECTIVE: To determine whether: (1) there is a secular increase in adult stature in Vanuatu, and (2) whether adult stature is positively associated with modernization in Vanuatu. METHODS: This study reports on stature measurements collected on 650 adult (age > 17 years) men and women from four islands of varying economic development in Vanuatu. Measurements were collected as part of the Vanuatu Health Transitions Research Project in 2007 and 201…
Larger FVC and FEV 1 among Tibetans compared to Han born and raised at high altitude
OBJECTIVES: This study compares forced vital capacity (FVC) and Forced Expiratory Volume at 1 Second (FEV1 ) of Tibetans with those of Han who were born and raised at high altitude. MATERIALS AND METHODS: FVC and FEV1 tests were conducted among 1,063 children and adolescents between the ages of 6 and 20 years, and 184 adults between the ages of 21 and 39 years who had lived their entire lives at 3200 m, 3800 m and 4300 m in Qinghai Provence, Peop…
Impact of modernization on adult body composition on five islands of varying economic development in vanuatu
OBJECTIVE: The Republic of Vanuatu, similar to other South Pacific island nations, is undergoing a rapid health transition as a consequence of modernization. The pace of modernization is uneven across Vanuatu's 63 inhabited islands, resulting in differential impacts on overall body composition and prevalence of obesity among islands, and between men and women. In this study, we investigated (1) how modernization impacts body composition between a…
Adult lipids associated with early life growth in traditional melanesian societies undergoing rapid modernization: A longitudinal study of the mid‐20th century
Both poor fetal development and accelerated post‐natal growth have been linked to adult dyslipidemias in many studies conducted in developed societies. It is not known, however, whether these relationships only characterize populations with typical Western diets or if they also may develop in groups at the early stages of a dietary transition. Our longitudinal study of traditional rural populations in the Southwest Pacific during a period of extr…
Responses of Han Migrants Compared to Tibetans at High Altitude
While many studies have compared Tibetans and low‐altitude born Han living at high altitude, few have carefully controlled the chronological age at which lowlanders migrated, the length of time they had lived at high altitude, their nutrition, and their socio‐economic status. This has produced an array of results that frequently do not support the hypothesis that Tibetans and Han show fundamental differences in their response to hypoxia. Unlike t…
Modernization and the onset of overweight and obesity in bougainville and solomon islands children: Cross‐sectional and longitudinal comparisons between 1966 and 1986
This set of cross‐sectional and longitudinal data from children and young adults in certain Bougainville and Solomon Islands populations undergoing rapid modernization during the period 1966–1986 reveals very different responses to essentially the same stimuli—the introduction and widespread availability of western dietary items and reductions in habitual activity. Our analyses of over 2,000 children and young adults first measured in 1966–1972, …
Growth of Han migrants at high altitude in central Asia
Han Chinese of low‐altitude descent have been living in Qinghai Province of Western China for at least two millennia. For most of this time they have lived at elevations under 2,500 m. However, during the last four decades an increasing number of Han have moved into high‐altitude towns at elevations over 3,000 m, and some above 4,000 m. There are now sufficient numbers of Han descendants who have been born and raised at high altitude to allow a c…
Morphological growth and thorax dimensions among Tibetan compared to Han children, adolescents and young adults born and raised at high altitude
Although genetic similarities cannot be ruled out, comparable dietary stress is a likely explanation for the similar and slow morphological growth of Han and Tibetans at high altitude. However, Han-Tibetan differences in thorax dimensions are likely a consequence of population (genetic) differences in the response to hypoxia during growth
Hematological differences during growth among Tibetans and Han Chinese born and raised at high altitude in Qinghai, China
This study describes the hemoglobin concentration ([Hb]) and hematocrit (HCT) of over 1,000 Tibetan and Han children, adolescents, and young adults who were born and raised at 3,200 m, 3,800 m, or 4,300 m in Qinghai Province, western China. At 3,200 m, no altitude effect is evident in the hematological characteristics of either group. At 3,800 m and 4,300 m, both groups show [Hb] and HCT values that are above low‐altitude norms. At both altitudes…
Lung function of Han Chinese born and raised near sea level and at high altitude in Western China
Forced vital capacity (FVC), forced expiratory volume at 1 second (FEV 1 ), and FEV 1 /FVC ratios were determined for 531 individuals of Han Chinese descent living at low altitude (250 m) near Beijing and for 592 individuals of Han descent who were born and raised at three high altitudes (3,200 m, 3,800 m, 4,300 m) in Qinghai Province, P.R.C. The study included males and females, ages 6–51 years. Thorax widths, depths, and circumferences of Han f…
Morphological growth of Han boys and girls born and raised near sea level and at high altitude in western China
This study compares the morphological characteristics of Han children, adolescents, and young adults who were born at 250 m near Beijing and at three high altitudes in Qinghai Province, Peoples Republic of China (3,200 m, 3,800 m, and 4,300 m). From ages 6 through 15, Han children growing up at high altitudes are significantly shorter, lighter, have less fat, and are less muscular than Han children growing up at low altitude. However, older adole…

Smoking and pulmonary function in five Solomon Island populations
The relationship between smoking and lung function was examined in a large sample of healthy Solomon Island Melanesians and Polynesians as part of a multidisciplinary study carried out in 1985 and 1986. Comparisons are made between samples of smokers and non‐smokers to determine if smoking is associated with a reduction in pulmonary function among males and females between 25 and 75 years of age. The results of this study indicate that cigarette …
Effects of acculturation and age on the exercise capacities of Solomon Islanders
Submaximal exercise tests were carried out on 197 females and 290 males from five populations in the Solomon Islands to determine how acculturation affects the fitness of different age and sex groups. Males and females in the least acculturated group show the highest fitness levels, reflecting strenuous work patterns. Subjects from the most acculturated groups exhibit the lowest levels of fitness, a consequence of their more sedentary life‐styles…
The Impact of Irrigation on the Demographic Structure of the Peshawar Basin of Northwest Pakistan
Biocultural Adaptations of the High Altitude Sherpas of Nepal
Blood pressure at rest and during exercise among Sherpas and Tibetan migrants in Nepal
Cultural factors affecting the demographic structure of a high altitude nepalese population
This study concerns the fertility of Sherpa and Tibetan women living at altitudes over 3,400 meters in Nepal. The average completed fertility (4.77 live births) and estimated crude birth rate (31 to 33 per 1,000) are low relative to low altitude peasant populations as well as to high altitude Andean peasants. Environmental phenomena (hypoxia, iodine deficiency) may be associated with retarded menarchial age and high infant mortality; but the majo…
