Environment driven changes in type 2 diabetes, overweight and obesity in an isolated Mixe community in the Valley of Oaxaca, southern Mexico
BACKGROUND: This study focused on type 2 diabetes mellitus (T2DM) in a group of adult Mixe, an Indigenous population from Oaxaca, Mexico. Mixe comprised an estimated 9.4% (n ≅ 90 000) of the Indigenous population in Oaxaca. Mexico. OBJECTIVE: This study focused on a group of adult Mixe, an Indigenous population from Oaxaca, Mexico. To compare the prevalence of T2DM, overweight (OW), obesity (OB), and hypertension (HTN) between 2007 and 2017 for a…
Covid-19 infection and mortality among non-pregnant indigenous adults in Mexico 2020-2022
Background: Indigenous individuals have higher rates of mortality and poverty in Mexico and more than half are marginalised, and COVID-19 pandemic aggravated the existing burden of health disparities. We aimed to analyse the effects of being indigenous and marginalised on coronavirus (COVID-19) infection fatality in Mexico. Methods: We identified 3 424 690 non-pregnant, COVID-19 positive adults ≥19 years in the Mexico national COVID-19 database w…
Do mating preferences remain the same when phenotypes change? Assortative mating for physical characteristics in an indigenous community in the valley of Oaxaca, southern Mexico
Assortative mating for physical characteristics did not differ between surveys conducted before (1978) and after (2000) major secular increases in height in the community, and any possible genetic effect of the secular trend on assortative was likely negligible.
Secular trends are associated with the demographic and epidemiologic transitions in an indigenous community in Oaxaca, Southern Mexico
OBJECTIVE: To test the hypothesis that secular changes in body size and age at menarche are related to the demographic and epidemiologic transitions in an indigenous community in Oaxaca, southern Mexico. METHODS: Data were derived from surveys of a Zapotec-speaking community conducted between 1968 and 2000. Segmented linear regressions of height, weight, BMI and recalled age at menarche on year of birth in cohorts of adults born before and after …
Geographic variation in the growth status of indigenous school children and youth in Mexico
OBJECTIVE: To analyze variation in the growth status of indigenous children and youth attending bilingual schools, escuelas albergues, for the indigenous population in México. MATERIALS AND METHODS: The children and youth attended escuelas albergues in 1,009 localities in 21 Mexican states in 2012. Heights and weights of 31,448 boys and 27,306 girls 6-18 years of age were measured by trained staff at each school; the BMI was calculated. The stude…
Natural selection and type 2 diabetes‐associated mortality in an isolated indigenous community in the valley of Oaxaca, southern Mexico
OBJECTIVE: This study tests the hypothesis that natural selection is associated with type 2 diabetes (T2D)-associated mortality and fertility in a rural isolated Zapotec community in the Valley of Oaxaca, southern Mexico. PARTICIPANTS AND METHODS: Mortality data and related demographic and genealogic information were linked with data for fertility, prereproductive mortality and family history of mortality attributed to T2D. Physician verified T2D…
Weight status of indigenous youth in Oaxaca, southern Mexico
Prevalence of overweight and obesity among indigenous youth in Oaxaca was higher with WHO than IOTF criteria, whereas prevalence of severe and moderate thinness was similar. Differences in estimates for overweight and obesity have implications for surveillance
Altitude effects on growth of indigenous children in Oaxaca, Southern Mexico
The effect of altitude of residence on the growth status of 11,454 indigenous school children 6–14 years of age in Oaxaca, southern Mexico, was examined. Indicators of living conditions (human development index [HDI], index of community nutritional risk [INR], index of marginalization [IM], index of relative isolation [II]) were regressed on z ‐scores for height, weight and BMI, and the residuals were regressed on altitude of residence (km). Inde…
Correlates of physical activity and inactivity in urban Mexican youth
OBJECTIVES: To evaluate correlates of physical activity in Mexico City school youth. METHODS: A cross-sectional survey was conducted with 1,004 school youth (490 males and 514 females), 9-18 years of age resident in Mexico City. Age, height, body mass index (BMI), socioeconomic status (SES), time viewing television and playing video games (physical inactivity), and perceived sport/physical activity status of mother and father were evaluated as po…
Secular change in height and weight of indigenous school children in Oaxaca, Mexico, between the 1970s and 2007
Improved growth status between the 1970s and 2007 presumably reflects better health and nutritional conditions in indigenous communities of Oaxaca. Mean heights in 2007, however, only approximate 5(th) percentiles of the US reference
Community well-being and growth status of indigenous school children in rural Oaxaca, southern Mexico
Secular change in muscular strength of indigenous rural youth 6–17 years in Oaxaca, southern Mexico
The data demonstrate secular changes in muscular strength in indigenous rural youth in a community in the process of transition from subsistence level agriculture to an economy less dependent upon agriculture
Age and secular effects on muscular strength of indigenous rural adults in Oaxaca, Southern Mexico
Grip strength and strength per unit size declined with age. Strength and strength/height tended to increase between 1978 and 2000, while the opposite occurred for strength/weight. Results likely reflected in changes in habitual physical activity patterns associated with the transition from subsistence agriculture to less economic dependence upon agriculture
Secular change in heights of indigenous adults from a Zapotec‐speaking community in Oaxaca, southern Mexico
Secular change in adult height of residents in a rural indigenous community in the Valley of Oaxaca was evaluated. Subjects were measured in 1971 (49 males, 26 females 19–70 years), 1978 (128 males, 124 females 19–82 years) and 2000 (155 males, 255 females 19–89 years). Heights were adjusted for estimated loss with age using two protocols; height at 21 years of age was also estimated. The effects of age and secular factors on measured and adjuste…
Socioeconomic variation in the growth status of urban school children 6–13 years in Oaxaca, Mexico, in 1972 and 2000
Socioeconomic variation in the growth status of urban school children 6–13 years of age in 1972 and 2000 was compared. The children were resident in the city of Oaxaca and were students in the same primary school in each year. Socioeconomic status (SES) was based on parental occupation. Height, sitting height, estimated leg length, weight, and the body mass index in 218 boys and 191 girls in 1972 and 173 boys and 166 girls in 2000 were compared. …
Growth status of indigenous school children 6–14 years in the Tarahumara Sierra, Northern Mexico, in 1990 and 2007
Positive secular changes in growth status have occurred in Tarahumara children 6-11 years in contrast to negligible changes among children 12-14 years. The results suggest recent improvements in health and nutrition sufficient to support a positive secular trend in younger children
Natural selection and demographic transition in a Zapotec-speaking genetic isolate in the Valley of Oaxaca, southern Mexico
The 'classic' demographic transition occurred in the mid-1950s and preceded the secular increase in body size. A 'critical mass' of environmental improvement appears to be necessary to activate secular improvements in growth status, possibly turning on a gene complex that interacts with the improved environmental conditions. The lead time from the onset of demographic transition phase II to beginning of the secular trend is approximately 25 years…
Secular change in the growth status of urban and rural schoolchildren aged 6–13 years in Oaxaca, southern Mexico
Significant secular increases in body size occurred between the 1970s and 2000, but there was considerable overlap between urban and rural children. Only secular gains in the BMI were significantly greater in urban than rural boys and girls and the magnitudes of urban-rural differences in the BMI were greater in 2000 than in the 1970s
Epidemiologic transition in an isolated indigenous community in the Valley of Oaxaca, Mexico
The objective of the present study is to analyze age‐specific mortality in a rural indigenous community in the throes of a secular increase in size in the Valley of Oaxaca, southern Mexico, over 30 years, 1970–1999. Variation in mortality by age group was analyzed over time for evidence of an epidemiological transition. The seasonal rain pattern in the Valley of Oaxaca (83% from May through September) was evaluated for its relationship with morta…
Overweight and obesity in a rural amerindian population in Oaxaca, Southern Mexico, 1968–2000
The purpose of this study was to evaluate secular change in the prevalence of overweight and obesity in a rural Zapotec Indian community in southern Mexico between 1968 and 2000. Cross‐sectional surveys of children 6–13 years, adolescents 13–17 years, and adults 19 years of age and older resident in a rural community in Oaxaca were conducted in 1968/1971, 1978, and 2000. Individuals present in the 1968, 1978, and 2000 surveys provided a small lon…
Craniofacial dimensions in children in rural Oaxaca, Southern Mexico
The objective of this investigation was to analyze the underlying cause(s) of secular changes in craniofacial dimensions among indigenous children in an isolated community in Oaxaca, southern Mexico, between 1968-2000. Subjects were schoolchildren resident in a rural, agrarian, Zapotec-speaking community in the Valley of Oaxaca, previously characterized as mildly-to-moderately undernourished with growth-stunting in 1968 and 1978. In 2000, childre…
Prostitution and Trafficking in Nine Countries
We interviewed 854 people currently or recently in prostitution in 9 countries (Canada, Colombia, Germany, Mexico, South Africa, Thailand, Turkey, United States, and Zambia), inquiring about current and lifetime history of sexual and physical violence. We found that prostitution was multitraumatic: 71% were physically assaulted in prostitution; 63% were raped; 89% of these respondents wanted to escape prostitution, but did not have other options …
Secular change in height, sitting height and leg length in rural Oaxaca, southern Mexico
There are major secular increases in height, sitting height and estimated leg length of children and adolescents of both sexes since 1978. Secular gains in height are of similar magnitude in boys and girls 6-13 years, but are greater in adolescent and young adult males than females. The secular increase in height of young adults of both sexes is smaller than that among adolescents. Estimated leg length accounts for about 60% of the secular increa…
Secular change in age at menarche in rural Oaxaca, southern Mexico
There is a major secular decline in the age at menarche of adolescent girls and young adult women between 1978 and 2000. The estimated rate of decline in adult women is about one-half of that in adolescent girls. The secular decline in age at menarche is consistent with corresponding secular gains height, sitting height and estimated leg length of children and adolescents in the community; corresponding secular gains are smaller in young adults 1…
Urban–rural contrasts in the physical fitness of school children in Oaxaca, Mexico
The physical fitness of school children resident in an urban colonia and in a rural indigenous community in Oaxaca, southern Mexico, was compared. Two measures of performance‐related fitness (standing long jump, 35‐yard dash [32 m]) and four measures of health‐related fitness (grip strength, sit and reach, timed sit‐ups, distance run) were taken on 355 rural (175 boys, 184 girls) and 324 urban (163 boys, 161 girls) school children, 6–13 years of …

Relative fat distribution
Skeletal maturia (Tanner‐Whitehouse II [TW II]), growth status, and motor fitness were compared in boys having high and low trunk/extremity skinfold ratios (T/E ratio). The T/E ratio was based on the sums of the subscapular and midaxillary, and the triceps and medial calf skinfolds. The sample included 80 boys, age 8 through 11 years, who represented the highest and lowest quartiles of the distribution of the T/E ratio (10 boys per quartile in ea…
Growth status of children 6-12 years from two different geographic regions of Mexico
The gap in height between well-off and lower socioeconomic status children in different regions of Mexico has been reduced, but there is an increase in the prevalence of overweight and obesity
Urban–rural contrasts in the physical fitness of school children in Oaxaca, Mexico
The physical fitness of school children resident in an urban colonia and in a rural indigenous community in Oaxaca, southern Mexico, was compared. Two measures of performance‐related fitness (standing long jump, 35‐yard dash [32 m]) and four measures of health‐related fitness (grip strength, sit and reach, timed sit‐ups, distance run) were taken on 355 rural (175 boys, 184 girls) and 324 urban (163 boys, 161 girls) school children, 6–13 years of …
Urban–rural contrasts in the growth status of school children in Oaxaca, Mexico
Children resident in an urban colonia were taller and heavier than children resident in a rural indigenous community. After controlling for age and body size, urban-rural differences in skeletal breadths and limb circumferences were reduced or eliminated, but skinfold thicknesses were greater in rural girls. The magnitude of urban-rural differences in body size has decreased over approximately 30 years in boys, but has increased in girls
