Purpose: Social disconnection, such as loneliness, is recognized as a significant public health concern in the United States, and young adult males may carry the greater burden of this issue when compared with their female peers. Little is known about the correlates of loneliness for this population. This study examines the social-ecological correlates of loneliness in young adult males. Methods: Males, aged 18 to 25 years, in the United States were recruited to take part in a cross-sectional electronic survey. Loneliness was assessed as a composite measure. The social-ecological correlates consisted of intrapersonal-level (e.g., social-demographic characteristics), interpersonal-level (e.g., adverse childhood experiences), community-level (e.g., life expectancy at the county level), and societal-level (e.g., idealized masculine gender) variables. A four-block hierarchical regression was performed with each block representing the respective social-ecological level. Results: Among the study sample (n = 495), the intra- and interpersonal variables significantly shared 10% and an incremental 3%, respectively, of the explained variance in loneliness. Mental health diagnosis (β = 1.06, 95% confidence interval [CI]: [0.54, 1.59]), childhood physical and emotional abuse (β = 0.21, 95% CI: [0.02, 0.39]), and childhood sexual abuse (β = 0.30, 95% CI: [0.01, 0.60]) were significantly associated with greater loneliness. Conclusion: The findings highlight that the micro-level (intra- and interpersonal) correlates may be most important in predicting loneliness in young adult males. Specifically, young males with a mental health diagnosis and those with greater experiences of childhood adversity are at potentially greater risk for loneliness. Implications for research, programming, and policy are highlighted. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the dietary contribution of culturally preferred foods in a population of Black Seventh-Day Adventists from the eastern and southern United States in order to improve the standard food frequency questionnaire.Design: Intake of such foods was assessed using a specially designed self-administered food frequency questionnaire consisting of a list of 60 items. A demographic questionnaire was administered by later telephone interview.Setting: Southern and northeastern United States.Subjects: One hundred and sixty-one Black Seventh-Day Adventists were selected from 60 congregations. Approximately half had Caribbean roots.Results: Among the special foods included, red beans stood out and were among the top five contributors to eight of nine selected nutrients. Various legumes, cruciferous vegetables, and okra-corn-tomatoes were the most frequently consumed special foods. Macaroni and cheese was an important contributor to total energy, fat, saturated fat, and protein. At least weekly consumption of red beans, rice and beans, pinto beans, black-eyed peas, plantains and poke salad was reported by 47%, 40%, 31%, 28%, 26% and 25% of subjects, respectively. These foods (largely the legumes) contributed 77% and 104% of the dietary reference intakes for folate and total fiber, respectively. On average, all these foods contributed an estimated 726 calories per day.Conclusions: These findings show that, in total, these foods make a major contribution to the diets of these subjects and that the most commonly eaten at least should be included in dietary questionnaires designed for this minority population.

In the literature on consumption and society, a growing body of theoretical and empirical research has analyzed consumer culture. Within this literature, however, the nation-state has largely been ignored as a direct consumer. This article examines how nation-states, through their militaries, act as consumers of nickel in the production of military weaponry. This is done through three case studies including the Canadian war effort in WWII, the U.S. campaign during the Korean War, and the transformation toward network-centric warfare undertaken by the U.S. between 1993 and 2001. I argue that the dynamic between nation-states and the industries that provide for their military consumption differs from consumer consumption due to the nation-state's unique legal and economic position. Bringing the nation-state into the discussion of consumption can provide an enhanced picture of the dynamics of consumption. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the relationship of diet to incident diabetes among non-Black and Black participants in the Adventist Health Study-2., Methods and Results: Participants were 15,200 men and 26,187 women (17.3% Blacks) across the U.S. and Canada who were free of diabetes and who provided demographic, anthropometric, lifestyle and dietary data. Participants were grouped as vegan, lacto ovo vegetarian, pesco vegetarian, semi-vegetarian or non-vegetarian (reference group). A follow-up questionnaire after two years elicited information on the development of diabetes. Cases of diabetes developed in 0.54% of vegans, 1.08% of lacto ovo vegetarians, 1.29% of pesco vegetarians, 0.92% of semi-vegetarians and 2.12% of non-vegetarians. Blacks had an increased risk compared to non-Blacks (odds ratio [OR] 1.364; 95% confidence interval [CI], 1.093-1.702). In multiple logistic regression analysis controlling for age, gender, education, income, television watching, physical activity, sleep, alcohol use, smoking and BMI, vegans (OR 0.381; 95% CI 0.236-0.617), lacto ovo vegetarians (OR 0.618; 95% CI 0.503-0.760) and semi-vegetarians (OR 0.486, 95% CI 0.312-0.755) had a lower risk of diabetes than non-vegetarians. In non-Blacks vegan, lacto ovo and semi-vegetarian diets were protective against diabetes (OR 0.429, 95% CI 0.249-0.740; OR 0.684, 95% CI 0.542-0.862; OR 0.501, 95% CI 0.303-0.827); among Blacks vegan and lacto ovo vegetarian diets were protective (OR 0.304, 95% CI 0.110-0.842; OR 0.472, 95% CI 0.270-0.825). These associations were strengthened when BMI was removed from the analyses., Conclusion: Vegetarian diets (vegan, lacto ovo, semi-) were associated with a substantial and independent reduction in diabetes incidence. In Blacks the dimension of the protection associated with vegetarian diets was as great as the excess risk associated with Black ethnicity., (Copyright © 2011 Elsevier B.V. All rights reserved.)

Objective: To assess race-specific validity of food and food group intakes measured using an FFQ., Design: Calibration study participants were randomly selected from the Adventist Health Study-2 (AHS-2) cohort by church, and then by subject-within-church. Intakes of forty-seven foods and food groups were assessed using an FFQ and then compared with intake estimates measured using six 24 h dietary recalls (24HDR). We used two approaches to assess the validity of the questionnaire: (i) cross-classification by quartile and (ii) de-attenuated correlation coefficients., Setting: Seventh-day Adventist church members geographically spread throughout the USA and Canada., Subjects: Members of the AHS-2 calibration study (550 whites and 461 blacks)., Results: The proportion of participants with exact quartile agreement in the FFQ and 24HDR averaged 46 % (range: 29-87 %) in whites and 44 % (range: 25-88 %) in blacks. The proportion of quartile gross misclassification ranged from 1 % to 11 % in whites and from 1 % to 15 % in blacks. De-attenuated validity correlations averaged 0·59 in whites and 0·48 in blacks. Of the forty-seven foods and food groups, forty-three in whites and thirty-three in blacks had validity correlations >0·4., Conclusions: The AHS-2 questionnaire has good validity for most foods in both races; however, validity correlations tend to be higher in whites than in blacks.

Objective: The goal of the prospective Adventist Health Study-2 (AHS-2) was to examine the relationship between diet and risk of breast, prostate and colon cancers in Black and White participants. This paper describes the study design, recruitment methods, response rates, and characteristics of Blacks in the AHS-2, thus providing insights about effective strategies to recruit Blacks to participate in research studies., Design: We designed a church-based recruitment model and trained local recruiters who used various strategies to recruit participants in their churches. Participants completed a 50-page self-administered dietary and lifestyle questionnaire., Participants: Participants are Black Seventh-day Adventists, aged 30-109 years, and members of 1,209 Black churches throughout the United States and Canada., Results: Approximately 48,328 Blacks from an estimated target group of over 90,000 signed up for the study and 25,087 completed the questionnaire, comprising about 26% of the larger 97,000 AHS-2-member cohort. Participants were diverse in age, geographic location, education, and income. Seventy percent were female with a median age of 59 years., Conclusion: In spite of many recruitment challenges and barriers, we successfully recruited a large cohort whose data should provide some answers as to why Blacks have poorer health outcomes than several other ethnic groups, and help explain existing health disparities.

Telepathology is the use of telecommunications technology as a means to facilitate transfer of image-rich pathology data between remote locations for the purposes of diagnosis, education, and research. Although varying levels of technology exist to accomplish this task, static image--based systems are currently the most widely used around the world. Field selection and image quality have often been identified as major impediments to the successful use of static images for diagnostic telepathology. Between November 1994 and July 1999, the Armed Forces Institute of Pathology (AFIP) performed electronic consultation on over 1,250 static image--based cases, recording a clinically significant concordance rate of 97.3% between telepathology and final diagnosis (in cases in which follow-up material was available). For the same subset of cases, an absolute concordance rate of 73.7% was attained. A review of the case flow and construction of the AFIP telepathology system is presented, as well as factors that have an impact on the diagnostic accuracy of static image-based telepathology sytems in general.
