RESUMO

Most Americans do not eat enough fruits and vegetables with significant variation by state. State-level self-reported frequency of fruit and vegetable consumption is available from the Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System (BRFSS). However, BRFSS cannot be used to directly compare states' progress toward national goals because of incongruence in units used to measure intake and because distributions from frequency data are not reflective of usual intake. To help states track progress, we developed scoring algorithms from external data and applied them to BRFSS 2011 data to estimate the percentage of each state's adult population meeting US Department of Agriculture Food Patterns fruit and vegetable intake recommendations. We used 24-hour dietary recall data from the National Health and Nutrition Examination Survey, 2007-2010, to fit sex- and age-specific models that estimate probabilities of meeting recommendations as functions of reported consumption frequency, race/ethnicity, and poverty-income ratio adjusting for intraindividual variation. Regression parameters derived from these models were applied to BRFSS to estimate the percentage meeting recommendations. We estimate that 7%-18% of state populations met fruit recommendations and 5%-12% met vegetable recommendations. Our method provides a new tool for states to track progress toward meeting dietary recommendations.

RESUMO

BACKGROUND: Iron deficiency is estimated to impact more than 1.6 billion individuals worldwide, affecting child, maternal, and perinatal mortality. Iron supplementation, fortification, and dietary diversification are strategies to reduce the prevalence of iron deficiency. However, there are relatively few studies demonstrating the effectiveness of iron-fortified wheat flour as an intervention. OBJECTIVE: To assess the relationship between average monthly per capita household consumption of iron-fortified wheat flour and iron deficiency among women of childbearing age in Oman. METHODS: Data were obtained from the National Micronutrient Status and Fortified Food Coverage Survey, 2004. Iron deficiency status was compared between women living in households with a monthly per capita consumption of iron-fortified wheat flour of 1 kg or more and women living in households with a monthly per capita consumption of iron-fortified wheat flour of less than 1 kg. The analyses excluded women with elevated or unknown levels of C-reactive protein and controlled for characteristics of the women and household demographics. RESULTS: Consumption of iron-fortified wheat flour was associated with a lower prevalence of iron deficiency among women in our sample (adjusted odds ratio, 0.60), after controlling for age, employment status, marital status, intake of iron or multivitamin supplements, self-reported presence of a blood disorder, household income, educational level of head of household, and family size. CONCLUSIONS: These results suggest that women in our study living in households with a greater consumption of iron-fortified wheat flour have a lower prevalence of iron deficiency; however, additional study is needed.

RESUMO

INTRODUCTION: Although Hispanics are a rapidly growing ethnic minority in the United States, the effect of acculturation on the proportion of Hispanics who meet national objectives for fruit and vegetable consumption has not been fully investigated. Our objective was to determine the extent to which ethnicity and acculturation (indicated by survey language preference) are associated with fruit and vegetable consumption among Hispanics in the United States. METHODS: Fruit and vegetable consumption among adult respondents to the 2009 Behavioral Risk Factor Surveillance System was determined from data collected from the 31 states and 2 territories that offered the fruit and vegetable screener in Spanish and English (n = 287,997). Logistic regression analyses were used to determine whether ethnicity (Hispanic vs non-Hispanic white) and survey language preference (English vs Spanish) were related to meeting objectives of consuming fruit 2 or more times per day and vegetables 3 or more times per day. RESULTS: More Hispanics (37.6%) than non-Hispanic whites (32.0%) and more Spanish-speaking Hispanics (41.0%) than English-speaking Hispanics (34.7%) ate fruit 2 or more times per day. Conversely, more non-Hispanic whites (28.5%) than Hispanics (18.9%) and more English-speaking Hispanics (21.8%) than Spanish-speaking Hispanics (15.8%) ate vegetables 3 or more times per day. All associations remained significant after controlling for covariates. CONCLUSION: Our findings have implications regarding how brief screeners can be used to determine possible dietary disparities among the Hispanic population in the United States and to monitor population goals to eliminate racial and ethnic health disparities.

RESUMO

There is increasing evidence that more than 70% of cancers including pancreatic, breast and prostate cancers as well as neurofibromatosis (NF) are highly addicted to abnormal activation of the Ser/Thr kinase PAK1 for their growth. So far FK228 is the most potent among the HDAC (histone deacetylase) inhibitors that block the activation of both PAK1 and another kinase AKT, downstream of PI-3 kinase. However, FK228 is still in clinical trials (phase 2) for a variety of cancers (but not for NF as yet), and not available for most cancer/NF patients. Thus, we have been exploring an alternative which is already in the market, and therefore immediately useful for the treatment of those desperate cancer/NF patients. Here we provide the first evidence that extracts of Chinese/ Japanese peppercorns (Zanthoxyli Fructus) from the plant Zanthoxylum piperitum called "Hua Jiao"/"Sansho", block selectively the key kinase PAK1, leading to the downregulation of cyclin D1. Unlike FK228, these extracts do not inhibit AKT activation at the concentrations that block either cancer growth or PAK1 activation. The Chinese pepper extract selectively inhibits the growth of NF1-deficient malignant peripheral nerve sheath tumor (MPNST) cells, without affecting the growth of normal fibroblasts, and suppresses the growth of NF1-deficient human breast cancer (MDA-MB-231) xenograft in mice. Our data suggest that these peppercorn extracts would be potentially useful for the treatment of PAK1-dependent NF such as MPNST, in addition to a variety of PAK1-dependent cancers including breast cancers.

RESUMO

Although somatostatin receptors have been detected in many normal and neoplastic tissues, little is known of their expression and function in peripheral nerve tumors. In the present study, we examined the expression of all 5 somatostatin receptor subtypes (sst1-5) in 3 normal peripheral nerves, 3 traumatic neuromas, 27 schwannomas, 18 neurofibromas, and 177 malignant peripheral nerve sheath tumors (MPNSTs) by immunohistochemistry as well as by Western blot and reverse transcriptase-polymerase chain reaction investigations in 2 normal peripheral nerves, one neurofibroma, 5 schwannomas, and 5 MPNSTs. Immunoreactive somatostatin receptors were not detectable in normal peripheral nerve and in nonneoplastic Schwann cell proliferations. In contrast, sst2A mRNA and protein was present in 89% of schwannomas. This receptor subtype was less frequently detected in neurofibromas (22%) and MPNSTs (15%). Interestingly, sst4 was seen in 32% of MPNSTs and was almost exclusively expressed in this malignant tumor type. In support of a role in Schwann cell tumor growth control by somatostatin was the observation of induced internalization of sst2A and inhibition of cell proliferation in an NF1-associated MPNST cell line. Moreover, administration of an sst2A-selective agonist resulted in induction of MPNST cell apoptosis. We conclude that peripheral nerve sheath tumors often express at least one functional somatostatin receptor. Furthermore, our findings suggest a potential clinical role for somatostatin receptor agonists in tumor imaging and/or treatment of schwannomas and MPNSTs.

RESUMO

BACKGROUND: Data on large scale community-level interventions on fruit and vegetable consumption targeting minority communities are lacking. This study examined whether a multicommunity intervention decreased disparities in fruit and vegetable consumption. MATERIALS AND METHODS: The Racial and Ethnic Approaches to Community Health (REACH) 2010 program was conducted among 16 black communities. Five-year trends (2001-2006) in self-reported fruit and vegetable consumption among the target population were compared with trends among white and black populations in 14 states where communities were located. RESULTS: The geometric mean of combined fruit and vegetable consumption in the REACH communities increased 7.4 % (P0.001) but did not change among white and black populations in comparison states (P0.05). Increased consumption in REACH communities was higher in the lower quintiles of consumptions. The disparity in fruits and vegetables consumption between comparison white population and blacks in REACH communities decreased by 33 %-from 0.66 to 0.44 times per day. The target population of 1.2 million people consumed fruits and vegetables about 21.9 million additional times per year as a result of the REACH program. CONCLUSION: This large community-based participatory intervention successfully reduced isparities in fruit and vegetable consumption between comparison white population and 16 disadvantaged black communities.

RESUMO

PURPOSE: To examine behavioral and environmental factors that may be related to dietary behaviors among U.S. high school students. DESIGN: Data were obtained from the 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. SETTING: The study was school-based. SUBJECTS: Study subjects were a nationally representative sample of students in grades 9 to 12 (n = 11,458). MEASURES: Variables of interest included meal practices, in-home snack availability, and intakes of healthful foods/beverages (fruits, vegetables, water, and milk) and less healthful foods/beverages (fried potatoes, pizza, and sugar-sweetened beverages). ANALYSIS: Sex-stratified logistic regression models were used to examine associations of meal practices and snack availability with dietary intake. Odds ratios (ORs) were adjusted for race/ethnicity and grade. RESULTS: Eating breakfast daily, frequent family dinners, and bringing lunch from home were associated with higher odds of consuming at least three healthful foods or beverages. High fast-food intake was associated with lower odds of healthful dietary intake and higher odds of sugar-sweetened beverage intake (female OR = 3.73, male OR = 4.60). Students who mostly/always had fruits and vegetables available at home had increased odds of fruits (female OR = 3.04, male OR = 2.24), vegetables (female OR = 2.12, male OR = 1.65), water (female OR = 1.82, male OR = 1.85), and milk intake (female OR = 1.45, male OR = 1.64). CONCLUSION: Encouraging daily breakfast consumption, frequent family dinners, and fruit and vegetable availability at home may lead to higher intakes of healthful foods among high school students.

RESUMO

OBJECTIVES: To examine the association of timing of introduction and frequency of fruit and vegetable intake during infancy with frequency of fruit and vegetable intake at age 6 years in a cohort of US children. METHODS: We analyzed data on fruit and vegetable intake during late infancy, age of fruit and vegetable introduction, and frequency of fruit and vegetable intake at 6 years from the Infant Feeding Practices Study II and the Year 6 Follow-Up (Y6FU) Study. We determined the percent of 6-year-old children consuming fruits and vegetables less than once per day and examined associations with infant fruit and vegetable intake using logistic regression modeling, controlling for multiple covariates (n = 1078). RESULTS: Based on maternal report, 31.9% of 6-year-old children consumed fruit less than once daily and 19.0% consumed vegetables less than once daily. In adjusted analyses, children who consumed fruits and vegetables less than once daily during late infancy had increased odds of eating fruits and vegetables less than once daily at age 6 years (fruit, adjusted odds ratio: 2.48; vegetables, adjusted odds ratio: 2.40). Age of introduction of fruits and vegetables was not associated with intake at age 6 years. CONCLUSIONS: Our study suggests that infrequent intake of fruits and vegetables during late infancy is associated with infrequent intake of these foods at 6 years of age. These findings highlight the importance of infant feeding guidance that encourages intake of fruits and vegetables and the need to examine barriers to fruit and vegetable intake during infancy.

RESUMO

According to the Dietary Guidelines for Americans, persons in the United States aged ≥2 years should increase their intake of certain nutrient-rich foods, including fruits and vegetables. Fruits and vegetables contribute important nutrients that are underconsumed in the United States. Higher intake of fruits and vegetables might reduce the risk for many chronic diseases including heart disease, stroke, diabetes, and some types of cancer. In addition, replacing high-calorie foods with fruits and vegetables can aid in weight management. However, most persons in the United States do not consume the recommended amounts of fruits and vegetables and other healthier food groups (e.g., whole grains or fat-free or low-fat dairy foods).

RESUMO

Few studies take into account the influence of family size on household resources when assessing income disparities in fruit and vegetable (F/V) consumption. Poverty income ratio (PIR) is a measure that utilizes both reported income and household size. We sought to examine state-specific disparities in meeting Healthy People 2010 objectives for F/V consumption by percent PIR. This analysis included 353,005 adults in 54 states and territories reporting data to the 2009 Behavioral Risk Factor Surveillance System in the United States. Percent PIR was calculated using the midpoint of self-reported income range and family size. The prevalences consuming at least two fruits and at least three vegetables per day were examined by percent PIR (<130% [greatest poverty], 130% to <200%, 200% to <400%, and ≥ 400% [least poverty]). The percent of adults consuming vegetables at least three times daily was significantly lower (21.3%) among those living at greatest poverty (<130% PIR) compared with 30.7% among those with least poverty (≥ 400% PIR). Daily consumption of vegetables at least three times was significantly lower among those with greatest poverty in a majority of states and territories surveyed (43 of 54). The overall percent of adults consuming fruits at least 2 times daily was also lower among those living at greatest vs least poverty, but the difference was smaller (32.0% vs 34.2%), with 14 states reporting a difference that was significantly lower among those with greatest poverty. Our study revealed that in 2009 a significantly lower proportion of US adults living at greatest poverty consumed fruits at least two times daily or vegetables at least three times daily compared with those with the least poverty, with greater disparity in vegetable intake. Policy and environmental strategies for increased affordability, access, availability, and point-of-decision information are approaches that may help disparate households purchase and consume F/V.

RESUMO

High intake of fruits and vegetables (FV) is associated with a decreased risk for many chronic diseases and may assist in weight management, but few children and adolescents consume the recommended amounts of FV. The pediatric practitioner can positively influence FV consumption of children through patient-level interventions (eg, counseling, connecting families to community resources), community-level interventions (eg, advocacy, community involvement), and health care facility-level interventions (eg, creating a healthy food environment in the clinical setting). This article reviews the importance of FV consumption, recommended intakes for children, and strategies by which pediatric practitioners can influence FV consumption of children.
