Dietary behavior and urinary gallic acid concentration differences among underserved elder racial and ethnic minorities in New York City.

PURPOSE: Diet and nutrition are important for cancer prevention. To investigate associations between dietary behavior, demographics, and risk of cancer, we assessed dietary behavior and urinary concentration of gallic acid, a polyphenol with anticancer properties found in various fruits and vegetables, in racial and ethnic minorities. METHODS: Ninety-one (91) participants were recruited from senior centers in East Harlem, New York City, a racially diverse and underserved community. A National Institute of Health (NIH)-validated dietary survey questionnaire-was used to collect dietary fruits and vegetables consumption data. Demographic and cancer information were also collected. All 91 participants completed the survey and forty-five (45) participants provided urine samples for gallic acid analysis. RESULTS: Gender differences were significantly associated with dietary behavior and urinary gallic acid concentration (UGAC). Female participants had a higher total daily intake of fruits and a significantly higher UGAC compared to male participants (p < 0.05). Age was negatively associated with the serving quantity of French fries/fried potatoes and white potatoes (p < 0.05), while positively associated with the daily intake frequency and daily intake of fruits (p < 0.05). Furthermore, Asian race was associated with higher daily intake frequencies of fruits and vegetable soup (p < 0.05), compared to other races. In a multivariate analysis, a significant association was observed between the serving quantities of fruits and other vegetables and UGAC (p < 0.05) after controlling for demographic characteristics. CONCLUSION: The observed differences in dietary behavior and UGAC in this study provide limited information on the association between demographic differences and cancer prevalence in elder racial and ethnic minorities. Future research should investigate this association further for potential implications in cancer prevention.

Dietary Behavior and Urinary Gallic Acid Concentrations in Older Minority Residents of East Harlem, New York City.

In this multidisciplinary study, we explored relationships between demographic factors, dietary habits, and gallic acid, a polyphenolic biomarker that correlates with self-reported dietary behaviors and negatively correlates with the incidence of cancer. Thirty-three (33) participants were recruited from a senior center in East Harlem, New York City, a racially diverse and underserved community. A National Institute of Health (NIH)-validated survey questionnaire was used to gather dietary behavior data, alongside demographic and cancer history information. Urine samples were obtained from participants for analyzing gallic acid content level. All 33 recruited participants completed the survey and 25 of them provided urine samples for gallic acid analysis. Associations between demographic factors and intake of certain foods were observed. Specifically, age was negatively associated with French fries/fried potatoes, cooked dried beans, and tomato soup intake (p < 0.05), and Black/African American race was associated with increased consumption of fruits and vegetables in comparison to Hispanic/Latino ethnicity (p < 0.05). No associations between urinary gallic acid levels and demographic information was observed. However, French fries/fried potatoes intake was significantly associated with urinary gallic acid concentration (p < 0.01). The small sample size limited the execution of meaningful statistical analysis. However, this study provided preliminary findings about the dietary behavior of older adults in East Harlem, New York City, which will serve as a basis for a future larger study to investigate nutrition/dietary education intervention on cancer prevention among diverse elderly residents in New York City.

Community-Clinical Linkage Intervention to Improve Colorectal Cancer Screening Among Underserved Korean Americans.

Korean Americans report the lowest and declined rates of colorectal cancer (CRC) screening, compared to general population in the United States. The present study aimed to evaluate the efficacy of a community-based multifaceted intervention designed to improve CRC screening among Korean Americans. A cluster-randomized trial involving 30 Korean church-based community organizations (n = 925) was conducted. Fifteen churches were assigned to intervention (n=470) and the other 15 to control (n = 455) groups. Main components of the intervention included interactive group education, patient navigation, physician engagement, and provision of fecal immunochemical test (FIT) kit. CRC screening rates were assessed at a 12-month follow-up. Participants in the intervention group were significantly more likely to receive CRC screening (69.3%) as compared with those in the control group (16%). The intervention was particularly effective in promoting FIT among the more disadvantaged individuals in the Korean American community. Regression analysis revealed that controlling for the intervention effect, male gender, high school education, annual income of $20,000-40,000 were significantly associated with increased screening by FIT, whereas English inefficiency was significantly and lack of health insurance was marginally significantly associated with decreased screening by colonoscopy/sigmoidoscopy. Culturally and linguistically appropriate multifaceted intervention combining FIT provision with community-clinical linkage has a potential to be a cost-effective and practical approach to effectively targeting hard-to-reach disadvantaged minority populations and enhance CRC screening to reduce cancer disparities.

Characterizing Occupational Health Risks and Chemical Exposures Among Asian Nail Salon Workers on the East Coast of the United States.

The products used in nail care services contain toxic chemicals. This study aimed to characterize occupational health risk factors and chemical exposures among Asian nail salon workers on the East Coast of the U.S. for informing the development of more effective, culturally appropriate interventions. We conducted a community-based participatory research (CBPR) study to characterize occupational health risks. A face-to-face, self-reported survey was performed, and personal exposure to volatile organic compounds (VOCs) was evaluated. Three VOCs, acetone, methyl methacrylate (MMA), and toluene, were measured using 3M 3500 organic vapor monitors. We collected data on 112 workers with 100 personal chemical exposure measurements from 25 nail salons. Self-reported health problems that emerged or worsened after participants started working in the nail salon industry included headaches (8%); lightheadedness (9.8%); and irritation to the nose, eyes, throat, and skin (21.2%). Approximately 70% of participants reported that they had been pregnant, 11.7% of whom had at least one miscarriage. The mean concentrations of acetone, MMA, and toluene were 18.51 parts per million (ppm), 39.45 ppm, and 0.09 ppm, respectively. Mean concentrations of acetone and MMA measured from salons in New York City were significantly lower than those measured in Philadelphia and southern New Jersey. CBPR proved to be as an efficient approach for recruiting hard-to-reach Asian immigrant nail salon workers. Adverse health symptoms and problems associated with providing nail salon services were identified in these workers. Further studies are needed to better understand the long-term health effects of chronic chemical exposures in nail salon environments.

Higher infant body fat with excessive gestational weight gain in overweight women.

OBJECTIVE: Gestational weight gain (GWG) is positively associated with birthweight and maternal prepregnancy body mass index (BMI) is directly related to infant fat mass (FM). This study examined whether differences exist in infant body composition based on 2009 GWG recommendations. STUDY DESIGN: Body composition was measured in 306 infants, and GWG was categorized as appropriate or excessive. Analysis of covariance was used to investigate the effects of GWG and prepregnancy BMI and their interaction on infant body composition. RESULTS: Within the appropriate group, infants from obese mothers had greater percent fat (%fat) and FM than offspring from normal and overweight mothers. Within the excessive group, infants from normal mothers had less %fat and FM than infants from overweight and obese mothers. A difference was found for %fat and FM within the overweight group between GWG categories. CONCLUSION: Excessive GWG is associated with greater infant body fat and the effect is greatest in overweight women.

Validity of a competing food choice construct regarding fruit and vegetable consumption among urban college freshmen.

OBJECTIVE: This paper presents the reliability and validity of a "competing food choice" construct designed to assess whether factors related to consumption of less-healthful food were perceived to be barriers to fruit and vegetable consumption in college freshmen. DESIGN: Cross-sectional, self-administered survey. SETTING: An urban public college with a large, diverse student population. PARTICIPANTS: A convenience sample of 408 college freshmen. VARIABLES MEASURED: A "competing food choice" construct and fruit and vegetable intake. ANALYSES: Factor analysis, Cronbach α, and correlation coefficients were used to determine the reliability and validity of the construct. RESULTS: Three factors were produced from the factor analysis of the 11-item competing food choice construct: "competitive food" barriers (Cronbach alpha = 0.73), fruit and vegetable-related "time" barriers (Cronbach alpha = 0.67), and "quality" barriers (Cronbach alpha = 0.64). Construct validity assessments revealed significant inverse correlations between fruit and vegetable consumption and competitive food barriers (r = -0.15, P < .01 current and r = -0.25, P < .01 prior) and time barriers (r = -0.12, P < .05 current and r = -0.10, P < .05 prior). CONCLUSIONS AND IMPLICATIONS: This "competing food choice" construct demonstrated satisfactory reliability and construct validity among college freshmen.

Relationship between body mass index and adiposity in prepubertal children: ethnic and geographic comparisons between New York City and Jinan City (China).

Body mass index (BMI) is often used as a surrogate estimate of percent body fat in epidemiological studies. This study tested the hypothesis that BMI is representative of body fatness independent of age, sex, ethnicity, and geographic location in prepubertal children. The study sample included a total of 605 prepubertal children (275 girls and 330 boys) of which 247 were Chinese from Jinan, Shandong, Mainland China, and 358 children were from various ethnic backgrounds in New York City (NYC): 121 Caucasians, 94 African Americans, and 143 Asians (Chinese and Korean). In this cross-sectional study, dual energy X-ray absorptiometry was used to quantify total body fat (TBF) and percent body fat (PBF). Prepubertal status was assessed by the criteria of Tanner. Multiple regression models were developed with TBF and PBF as the dependent variables and BMI, age, sex, and ethnicity as independent variables. Multiple regression analysis showed that BMI alone explained 85% and 69% of between-subject variance for TBF and PBF, respectively. Sex was a significant contributor to the models (P<0.001) with girls having higher TBF and PBF than boys. Ethnicity and geographic location were significant contributors to the model (P<0.0001) with Asians (Jinan and NYC Asians) having higher PBF than all non-Asian groups (P<0.0001), and Jinan Asians having higher TBF and PBF than NYC-Asians. Among prepubertal children, for the same BMI, Asians have significantly higher PBF compared with African Americans and Caucasians. Caution is warranted when applying BMI across sex and ethnic prepubertal groups.

Mediation by nitric oxide of the stimulatory effects of ethanol on blood flow.

The contribution of nitric oxide (NO) to the hemodynamic effects associated with alcohol oxidation was assessed in rats given either ethanol or water by gastric tube, with and without pre-treatment with either the NO synthase inhibitor N(omega)-monomethyl-L-arginine (L-NMMA; 15 mg/Kg i.p.) or the alcohol dehydrogenase inhibitor 4-methylpyrazole (4-MP; 82 mg/Kg i.p.). Alcohol increased plasma NO (measured with chemiluminescence) by 63%. This was prevented by either L-NMMA or 4-MP. Cardiac output and regional blood flows were determined with 57Cobalt-labeled microspheres. Alcohol markedly enhanced portal blood flow (130 +/- 6 ml/min/Kg vs. 62 +/- 4, in controls; p < 0.01) with no changes in the hepatic, splenic or pancreatic arterial blood flows, indicating that the vasodilatation is mainly mesenteric. In addition, it quadrupled the coronary blood flow, doubled the renal flow and increased cardiac output by 38%, with no significant changes in pulmonary, cerebral or testicular flows. All the stimulatory effects of ethanol on flow, as well as the rise in NO levels, were prevented by L-NMMA, incriminating NO as the mediator of the hemodynamic effects of ethanol oxidation, acting probably via acetate and adenosine.

Dilinoleoylphosphatidylcholine is responsible for the beneficial effects of polyenylphosphatidylcholine on ethanol-induced mitochondrial injury in rats.

Chronic ethanol consumption depletes phosphatidylcholines (PC) in membranes and hepatic mitochondria are an early target of this toxicity. Our previous studies showed that soybean-derived polyenylphosphatidylcholine (PPC), attenuated mitochondrial liver injury. Since dilinoleoylphosphatidylcholine (DLPC) is the major component of PPC, we assessed whether it is responsible for the protection of PPC. Forty-two male rats were fed the following liquid diets for 8 weeks: Control; Control with DLPC (1.5 g/1000 Calories (Cal); Alcohol (36% of Cal); Alcohol with DLPC (1.5 g/1000 Cal) and Alcohol with PPC (3 g/1000 Cal). As expected, ethanol feeding diminished the capacity of hepatic mitochondria to oxidize glutamate and palmitoyl-1-carnitine, and also decreased the activity of mitochondrial cytochrome oxidase. These effects were equally prevented by either PPC or DLPC. In conclusion, DLPC fully reproduced PPC's protective action and may be effective in the prevention or delay of more severe liver damage.
