Latino racial choices: the effects of skin colour and discrimination on Latinos’ and Latinas’ racial self-identifications

Abstract

Are predictions that Hispanics will make up 25 per cent of the US population in 2050 reliable? The authors of this paper argue that these and other predictions are problematic insofar as they do not account for the volatile nature of Latino racial and ethnic identifications. In this light, the authors propose a theoretical framework that can be used to predict Latinos’ and Latinas’ racial choices. This framework is tested using two distinct datasets – the 1989 Latino National Political Survey and the 2002 National Survey of Latinos. The results from the analyses of both of these surveys lend credence to the authors’ claims that Latinas’ and Latinos’ skin colour and experiences of discrimination affect whether people from Latin America and their descendants who live in the US will choose to identify racially as black, white or Latina/o.     

Total and Central Obesity among Elderly Hispanics and the Association with Type 2 Diabetes

Objective: To report the prevalence of total and central obesity in a representative sample of Puerto Rican and Dominican elders in Massachusetts, to compare them with a neighborhood‐based group of non‐Hispanic white elders, and to examine associations of obesity indices with the presence of type 2 diabetes. Research Methods and Procedures: We examined the prevalence of overweight, obesity, and central obesity in 596 Hispanics of Caribbean origin, ages 60 to 92 years, and 239 non‐Hispanic whites, and tested linear and logistic regression models to determine associations among body mass index (BMI), waist circumference (WC), and diabetes. Results: Obesity (BMI ≥ 30 kg/m²) was prevalent among all ethnic groups, ranging from 17% to 29% for Dominican and Puerto Rican men, respectively, and from 29% to 40% for non‐Hispanic white and Dominican women, respectively. These differences were not statistically significant. Among Hispanic men and women, diabetes was prevalent across all BMI and WC categories but tended to be greatest among those with BMI of 25 to 29 kg/m² (41% to 43%). In contrast, diabetes was most prevalent in the obese group (36% to 45%) of non‐Hispanic whites. Both BMI and WC were associated with the presence of diabetes, but the coefficients were greater for non‐Hispanic whites than for Hispanics. Discussion: Caribbean Hispanics and non‐Hispanic whites living in the same Massachusetts localities had high prevalences of overweight and obesity. Total and central obesity exerted a differential effect on the presence of diabetes among ethnic groups; for Hispanics, diabetes was prevalent even among non‐obese individuals, whereas for non‐Hispanic white women, the prevalence of diabetes was strongly associated with total and central obesity. Additional research is needed to investigate the factors associated with the differential effect of obesity on the prevalence of type 2 diabetes among Hispanic and non‐Hispanic white elders.     

The survivance of French Canadians in New England (1865–1930): History,geography and demography as destiny*

This article analyses the Urban Poverty and Family Life Survey of Chicago and an urban subsample of the National Survey of Families and Households to examine race and ethnic variation in the occurrence and consequences of birth versus marriage pathways to family formation. Results based on multiple‐decrement life table analysis and multi‐variate life table regression analysis reveal strong race and poverty effects on pathways to family formation, but Hispanic origin does not systematically influence the odds that women will enter family life via marriage versus birth. We show stronger race effects on pathways to family formation for the Chicago sample owing to the much higher incidence of teen parenting among black inner‐city residents. Results also suggest lasting economic consequences of non‐marital fertility, irrespective of whether women eventually marry or divorce subsequent to a premarital birth.     

Quality of life in Mexican-American children following a weight management program

Objective: The objective was to evaluate quality of life (QOL) in at‐risk‐for‐overweight and overweight Mexican‐American children after participating in 6 months of intensive weight management or self‐help. Research Methods and Procedures: Eighty sixth‐ and seventh‐grade at‐risk‐for‐overweight (BMI ≥85th to <95th percentile) and overweight (BMI ≥95th percentile) Mexican‐American children were randomly assigned to either intensive instructor‐led intervention (ILI) or self‐help (SH). The ILI condition included daily participation for 12 weeks in a school‐based program comprised of nutrition education, physical activity, and behavior modification, followed by ongoing monthly maintenance. QOL was assessed at baseline and 6 months via child self‐report PedsQL. QOL outcomes were compared across treatment groups, and the impact of change in zBMI on change in QOL was evaluated. Results: Children in the ILI condition not only achieved significantly greater weight loss (zBMI, ?0.13 ± 0.14; p < 0.001) but also significantly greater physical QOL improvements than those in the SH condition at 6 months (p < 0.05). Furthermore, physical QOL increases were associated with zBMI reduction (p < 0.05). However, neither psychosocial nor total QOL was significantly impacted by intervention or zBMI change. Discussion: These findings show that even modest decreases in zBMI after weight management result in improved physical QOL in Mexican‐American children. These results illustrate the clear need to include evaluation of QOL in the process of identifying effective weight management programs.     

Party political preferences of US Hispanics: The varying impact of religion,social class and demographic factors

The focus of this article is the pattern of party political preferences among the fast‐growing and increasingly politically significant Hispanic population. The source of our data is the 1990 City University of New York [CUNY] National Survey of Religious Identification, a nationally representative sample that includes 4,868 Hispanic adult respondents. One unique aspect of our large data set is that for the first time we disaggregate the one‐third who are Protestant and of No Religion from the Roman Catholic majority of Hispanics in order to see how religious identification affects political outlook. We found that Hispanics are most likely to be Democrats: 41 per cent, compared with 27 per cent who identified as Independents and 24 per cent as Republicans. Our research suggests that Hispanics are rapidly adopting mainstream American political characteristics. As a whole, the Hispanic population politically resembles non‐Hispanic white America more closely than it does black America. Among Hispanics, Protestantism and higher income favour the Republicans, and femaleness and older age assist the Democrats. The local political environment and individual social attributes are the determining factors in Hispanic political preferences. In fact, the geographical variable, state of residency, has the strongest effect on Democratic Party preference in the multivariate analysis. Overall, the dynamics of social trends among Hispanics seem to favour the Republican Party.     

Use of native tree species by an hispanic community in Panama

We investigated the use of plants collected in the wild by a small farming community in Central Panama to document the importance of noncultivated plants by tropical, nonforest-dwelling, nonindigenous people. We visited the community to observe what wood was used to build houses and interviewed local people about medicinal and edible plants collected in the wild state. The community reported use of 119 noncultivated plant species, including 108 tree species, three shrubs, two herbs, four lianas, and two vines. The majority (71) of the species were used for building homes. Other products built with wood collected in the wild were diverse kinds of tools, containers, cages, and fences. The second most important use of wild plants, in terms of number of species, was firewood, for which 40 species were mentioned by the community. Other uses included fruit for human consumption (20 species). Most of the species (82 of 119) were collected in secondary forests near the community, whereas another large group (47 species) were collected in mature forest. Fewer species were harvested in shrubby regrowth or from isolated trees in farm land. Nearly all the species (111 of 119) were native to the area, and never cultivated locally, but 15 species were considered especially valuable, and were often protected when found as juveniles. Only six of the species are commonly used in reforestation programs in Panama. We conclude that even hispanic communities in tropical Latin America, living outside the forest, with no Amerindian inhabitants, make frequent use of the great diversity of trees native to the region.     

Seroprevalence of Helicobacter pylori in Hispanics living in Puerto Rico: A population‐based study

Background

Helicobacter pylori is an important etiologic factor for peptic ulcers and gastric cancer, one of the top ten leading causes of cancer death in Puerto Rico. However, the prevalence of H. pylori infections in this population was previously unknown. The aim of this study was to examine the seroprevalence of H. pylori and its associated risk factors in Puerto Rico.

Materials and Methods

A cross‐sectional study was designed using an existing population‐based biorepository. Seropositivity was determined using the Premier^? H. pylori immunoassay. Helicobacter pylori seroprevalence was estimated with 95% confidence using marginal standardization following logistic regression. To assess the risk factors associated with H. pylori seropositivity, a multivariable log‐binomial model was fitted to estimate the prevalence ratio (PR) and its 95% confidence interval (95% CI).

Results

A total of 528 population‐based serum samples were analyzed. The mean age of the study population was 41 ± 12 years, of whom 55.3% were females. The overall seroprevalence of H. pylori was 33.0% (95% CI = 28.3%‐38.1%). Increasing age and having <12 years of education were significantly (P < .05) associated with H. pylori seropositivity in the multivariable model; however, residing in counties with low population density reached marginal significance (P = .085).

Conclusions

We report that H. pylori infection is common among Hispanics living in Puerto Rico. The H. pylori seroprevalence observed in Puerto Rico is similar to the seroprevalence reported in the overall population of the United States. The association between H. pylori seroprevalence and the risk factors analyzed offers insight into the epidemiology of gastric cancer in Puerto Rico and warrants further investigation.

     

The effects of inbreeding on DNA profile frequency estimates using PCR-based loci

Estimates of inbreeding were determined using Wright's F_ST for loci used for PCR-based forensic analyses. The populations analyzed were African Americans, Caucasians, Hispanics, and Orientals. In most cases the F_ST values at each locus were less than 0.01. The F_ST values over all loci for African Americans, Caucasians, and Orientals ranged from 0.0015 to 0.0048. No substantial differences were observed for DNA profile frequency estimates when calculated under the assumption of independence or with the incorporation of F_ST.Editor's commentsThe author provides an empirical study to accompany the papers by Balding and Nichols and Brookfield in this volume. As may have been expected, F_ST values for large heterogeneous populations such as Caucasian or African American are very small.
