Risk Factors Associated with Vitamin D Status among Older Puerto Rican Adults.

BACKGROUND: Vitamin D deficiency has been associated with health problems globally, but there is limited information on vitamin D status and associated risk factors among adults in underserved populations. OBJECTIVE: This study aimed to identify risk factors for vitamin D deficiency/insufficiency among Puerto Rican adults from the Boston Puerto Rican Health Study (BPRHS). METHODS: A total of 822 adults (45-75 y, at baseline) were included in these analyses. Deficiency was defined as serum 25-hydroxyvitamin D [25(OH)D] <30 and insufficiency as 30 to <50 nmol/L. Dietary intake was assessed with a validated FFQ. Associations between risk factors, including dietary vitamin D, supplement use, ancestry, skin pigmentation, months in the past year spent in a southern climate, and serum 25(OH)D were assessed with multivariable general linear models. RESULTS: Approximately 13% of participants were deficient in 25(OH)D and another 43% insufficient. Skin pigment was associated with 25(OH)D using 3 measures, greater African ancestry (ß ± SE) (-7.74 ± 2.91, P = 0.01); interviewer assessed dark or medium, compared with white, skin tone, (-5.09 ± 2.19, P = 0.02 and -5.89 ± 1.58, P < 0.001, respectively); and melanin index of the upper inner right arm, assessed using a spectrophotometer (-2.04 ± 0.84, P = 0.02). After adjusting for ancestry, factors associated with lower serum 25(OH)D included smoking (-4.49 ± 1.58, P = 0.01); BMI (-0.21 ± 0.10, P = 0.04); and spring compared with autumn blood draw (-4.66 ± 1.68, P = 0.004). Factors associated with higher serum 25(OH)D included female sex compared with male (4.03 ± 1.58, P = 0.01); dietary vitamin D intake µg/d (0.71 ± 0.25, P < 0.004); vitamin D supplement use (4.50 ± 1.87, P = 0.02); income to poverty ratio (0.01 ± 0.01, P = 0.06), and months in a southern climate during the past year (0.96 ± 0.56, P = 0.09). CONCLUSIONS: Vitamin D deficiency/insufficiency was prevalent in this Puerto Rican population living in the northeastern USA. Several factors were associated with this, which may assist in identifying those at risk. Interventions are needed to improve serum 25(OH)D concentration, particularly among those with limited exposure to sunlight.

Development of a cognitive behavioral therapy with integrated mindfulness for Latinx immigrants with co-occurring disorders: Analysis of intermediary outcomes.

Objectives: Transdiagnostic interventions have been increasingly used in the management of a variety of mental health and substance use conditions, and in the context of chronic stress. We discuss the development and evaluation of the Integrated Intervention for Dual Problems and Early Action (IIDEA), a 10-session manualized intervention that includes cognitive therapy and mindfulness practice designed to improve symptoms of anxiety, depression, posttraumatic stress, and co-occurring substance use problems. Methods: In this secondary analysis of a randomized-controlled trial of IIDEA conducted with an international sample of immigrant Latinx in the United States and Spain, we evaluate intermediate outcomes-mindful awareness, working alliance with clinician and illness self-management-and integrate statistical findings with results from qualitative interviews with participants. Results: The IIDEA intervention group showed higher levels of mindful awareness, illness self-management, and working alliance over an enhanced treatment as usual control group (usual treatment plus scheduled assessments) and qualitative data offer insights into the importance of therapeutic alliance and integration of mindfulness practice with cognitive therapy management skills. Conclusions: Findings suggest that skills related to the studied intermediary outcomes can be helpful for Latinx immigrants experiencing circumstances of ongoing exposure to adversity and traumatic stress.

Further Exploration of Treatment Response in Latinos with Comorbid Asthma and Panic Disorder: A Brief Report of HRV and ETCO2 as Potential Mediators of Treatment Response.

Heart rate variability (HRV) and end tidal CO2 (ETCO2) in relation to treatment response have not been studied in Latino populations or in comorbid asthma and panic disorder (PD). An extension of previously published research, the current study explored psychophysiological variables as possible mediators of treatment response. Latino treatment completers (N = 32) in the Bronx with asthma-PD received either Cognitive-Behavioral Psychophysiological Therapy (CBPT) or Music Relaxation Therapy (MRT). CBPT included HRV-biofeedback (HRVB); in-the-moment heart rate data to help an individual learn to influence his/her own heart rate. The sample was primarily female (93.8%) and Puerto Rican (81.25%). Treatment groups did not differ on demographics, except for less education in CBPT. The Panic Disorder Severity Scale (PDSS) and Asthma Control Questionnaire (ACQ) assessed changes in symptoms. HRV and ETCO2 were measured at four of eight therapy sessions. Baseline ETCO2 and changes in HRV from first to last of psychophysiology sessions were investigated as mediators of change on ACQ and PDSS. Mixed model analyses indicated in the CPBT group, changes in both asthma control and PD severity were not mediated by changes in HRV. In the CBPT and MRT groups combined, changes in PD severity were not mediated by baseline ETCO2. These findings may be due to the brevity of HRVB in CBPT, multiple treatment components, ETCO2 not directly targeted, and/or unique physiological pathways in Latinos with asthma-PD.

Body Image, Physical Activity and Cultural Variables Underlying Race and Ethnicity among Latino Men.

BACKGROUND: Overweight and obesity is a significant public health concern among Latino men. Common correlates of obesity that have been examined in previous studies are diet, physical activity, and body image. OBJECTIVES: The aim of this study was to examine whether or not there are differences in body image, physical activity and cultural variables between Mexican and Puerto Rican men. METHODS: Participants completed a health and culture interview, anthropometric measures, a dietary assessment, and an objective measure of physical activity. The results are from the 203 participants who completed the health and culture interview. RESULTS: Mexicans and Puerto Ricans did not differ in their current and ideal body image, body image discrepancy, body satisfaction or how they described their weight. Puerto Ricans watched a greater number of hours of television per day than Mexicans (p < .01). There were no significant differences in their participation in any regular activity designed to improve or maintain their physical fitness, the number of times or length they engaged in this activity, or in their perceived exertion during this activity. Puerto Ricans reported a higher level of familism (p < .01) and machismo (p < .05) than Mexicans. There were no ethnic differences in folk illness beliefs, fatalism or personalism, acculturation level, acculturative stress, or ethnic identity. CONCLUSIONS: Results are discussed in relation to the development of healthy eating, physical activity and body image interventions for Puerto Rican and Mexican men.

Findings From a Randomized Trial of Weight Gain Prevention Among Overweight Puerto Rican Young Adults.

OBJECTIVE: Assess impact of multimodality weight gain prevention intervention. METHODS: Randomized clinical trial among 39 overweight young Puerto Rico college students using 10 weekly peer-support sessions promoting dietary, physical activity, and other lifestyle changes enhanced by stress-reduction and mindfulness approaches. Body mass index (BMI) and self-reported behaviors were measured at baseline and at 10 weeks and 6 months after baseline. RESULTS: At the completion of the intervention, BMIs in the experimental arm were 0.8 units lower than at baseline (z = -3.0; P = .008) and 1.2 lower at 6 months after baseline (z = -4.1; P < .001); BMIs in the control arm were 0.7 higher (z = 2.7; P = .02) at 10 weeks and 0.8 higher at 6 months (z = 3.1; P = .005). Group × time interaction confirmed that BMI differed significantly over time between arms (χ2 = 26.9; degrees of freedom = 2; P < .001). Analysis of behavioral changes was mostly inconclusive although the experimental arm reported a considerable increase in walking at 10 weeks. Qualitative data suggested that yoga and mindfulness components were particularly useful for motivating participants to maintain healthier lifestyle patterns. CONCLUSIONS: Body mass index in the experimental arm decreased at the end of intervention and was maintained at 6 months' follow-up.

"Footprints in the Bathroom": The Role of Spirituality in Patient Diagnosis.

CASE: Lucy is a 12-year-old Latina whose mother brought her to the pediatric clinic for help with her anxiety symptoms, "hearing voices," and episodes of "spacing out." Lucy did not cry at birth secondary to vocal cord paralysis and still has the tracheostomy performed at a few days of life. In addition to her neonatal intensive care unit stay, she has been hospitalized for pneumonia. Her mother says she is "sickly" and has a weak immune system due to her asthma symptoms. Lucy also experiences somatic complaints related to gastroesophageal reflux and constipation.Lucy is described as being "in another world" and must be called several times before she responds. Lucy states she is nervous "all the time" and often experiences a fast heartbeat, chest pain, and headache. Her attention and internalizing problems began at age 4 years and have worsened since she entered adolescence. When she is alone in the dark, she sees an unknown person and becomes frightened. She hears the voice of her paternal uncle telling her something will harm her mother and runs crying to "check" on her. Lucy also says she hears voices of paternal family members fighting. She has dreamed that her paternal uncle stabbed her in an alley. Lucy reports experiencing sadness and feelings of wanting to die. She has not tried to harm herself and has no plan to do this. She states that she does not know when she is awake or asleep and "hate people talking in my head." She does not report drug use.Lucy's family is bilingual, English and Spanish. Her mother works part-time as a nutritionist, and her father is a machinist. Her father receives counseling for anger management, and there have been previous unsub- stantiated child abuse reports involving Lucy and her younger brother. The maternal uncle has been involved in a gang and attempts to phone Lucy's mother, who does not wish to have contact with him. Lucy's mother expresses strong Christian religious and spiritual beliefs, including demons and spirits that may enter her home and can be cast off with prayer. Recently, the family purchased a "cuadro" (picture) at a yard sale, and Lucy's mother said this resulted in footprints in the bathroom that are disappearing with prayer, guidance from the church minister, and discarding of the "cuadro."The primary pediatrician ordered a home school program, given Lucy's frequent illnesses. She is progressing well with a special education teacher. Her recent psychological evaluation at school showed a below average nonverbal intelligence quotient, with strengths in the areas of perceptual, logical, and abstract relationships. Lucy's mother in the past has been hesitant to follow through with psychiatric evaluation because "it is up to God."In the clinic, she is pale and slender with an ethereal look. She is awake and alert with appropriate affect and mentation. Her tracheostomy is intact without any respiratory distress noted. There are no signs of drug use or active hallucinations. You are left wondering whether these voices need psychiatric management.

Faith, Family, Filiality, and Fate.

OBJECTIVE: What is the characterization of family involvement in health decisions, filial piety, religiosity/spirituality, and fatalism as they relate to attitudes/intentions toward end-of-life (EOL) planning/decision making among elderly Dominicans and Puerto Ricans in East Harlem, New York City? METHOD: An exploratory study using grounded theory and domain analysis was conducted with 51 elderly Dominicans and Puerto Ricans. Purposive and emerging themes were identified by three coders. RESULTS: Purposive themes were family involvement in health decisions/filial piety and religiosity/spirituality/fatalism and for clinical EOL-related terms; emerging themes were accessing/using EOL care, autonomy, influence of death/dying on own future care decisions, and death/dying is a private matter. IMPLICATIONS: The recommendations for community members are to empower awareness of EOL issues, engage providers regarding cultural needs, and clarification of advance care planning (ACP) function; the recommendations for providers are to engage patients to enhance culturally responsive care, clarify ACP function, and ask patients about preference for roles of family and God in decisions; the recommendations for policy makers are to enhance palliative education/access and immigration status research protections.

Dihydrofolate reductase 19-bp deletion polymorphism modifies the association of folate status with memory in a cross-sectional multi-ethnic study of adults.

BACKGROUND: Folate status has been positively associated with cognitive function in many studies; however, some studies have observed associations of poor cognitive outcomes with high folate. In search of an explanation, we hypothesized that the association of folate with cognition would be modified by the interaction of high-folate status with a common 19-bp deletion polymorphism in the dihydrofolate reductase (DHFR) gene. To our knowledge, the cognitive effects of this gene have not been studied previously. OBJECTIVE: We examined the association between cognitive outcomes with the 19-bp deletion DHFR polymorphism, folate status, and their interaction with high or normal plasma folate. DESIGN: This was a pooled cross-sectional study of the following 2 Boston-based cohorts of community living adults: the Boston Puerto Rican Health Study and the Nutrition, Aging, and Memory in Elders study. Individuals were genotyped for the DHFR 19-bp deletion genotype, and plasma folate status was determined. Cognitive outcomes included the Mini-Mental State Examination, Center for Epidemiologic Studies Depression Scale, and factor scores for the domains of memory, executive function, and attention from a set of cognitive tests. RESULTS: The prevalence of the homozygous deletion (del/del) genotype was 23%. In a multivariable analysis, high folate status (>17.8 ng/mL) was associated with better memory scores than was normal-folate status (fourth-fifth quintiles compared with first-third quintiles: ß ± SE = -0.22 ± 0.06, P < 0.01). Carriers of the DHFR del/del genotype had worse memory scores (ß ± SE = -0.24 ± 0.10, P < 0.05) and worse executive scores (ß = -0.19, P < 0.05) than did those with the del/ins and ins/ins genotypes. Finally, we observed an interaction such that carriers of the del/del genotype with high folate had significantly worse memory scores than those of both noncarriers with high-folate and del/del carriers with normal-folate (ß-interaction = 0.26 ± 0.13, P < 0.05). CONCLUSIONS: This study identifies a putative gene-nutrient interaction that, if confirmed, would predict that a sizable minority carrying the del/del genotype might not benefit from high-folate status and could see a worsening of memory. An understanding of how genetic variation affects responses to high-folate exposure will help weigh risks and benefits of folate supplementation for individuals and public health.

Association between maternal diet factors and hemoglobin levels, glucose tolerance, blood pressure and gestational age in a Hispanic population / Asociación entre los factores de la dieta y los niveles de hemoglobina, tolerancia a la glucosa, presión arterial y edad gestacional en una población hispana

The aim of this study was to describe the dietary patterns of pregnant women in northern Puerto Rico and explore associations between diet factors with pregnancy related measurements. This analysis is based on the Puerto Rico Testsite for Exploring Contamination Threats (PROTECT), a prospective cohort that is studying environmental risk factors for preterm births in PR. Participants completed a food frequency questionnaire (FFQ) around 20-28 weeks of gestation. The following pregnancy related measures were collected from the medical records: hemoglobin, blood glucose, blood pressure and gestational age. Potential associations between diet factors and pregnancy measures were assessed using chi square analysis with SPSS. A total of 180 participants completed the FFQ; low hemoglobin levels was found in 19.2%, high blood glucose levels was found in 21.1% by fasting blood glucose test and 24.6%by 1-hour 50 g oral glucose screening test, high blood pressure was found in 2.9% (systolic) and 6.5% (diastolic), and pre-term birth was found in 10.4% of the participants. High consumption of rice, desserts and sweets was associated with higher levels of fasting blood glucose levels (p<0.05), while high consumption of vegetables was associated with higher 1-hour glucose challenge test (p<0.05).No other significant associations were found. In conclusion, consumption of high dense energy food diets in pregnancy, such as rice, sweets and desserts, can lead to high levels of blood glucose and can be a potential predictor of other pregnancy complications during pregnancy in these study participants, such as gestational diabetes.

El objetivo de este estudio fue describir los hábitos alimentarios de mujeres embarazadas en Puerto Rico y explorar la asociación entre factores dietarios y medidas del embarazo. Este fue un análisis de datos basado en un estudio de cohorte prospectivo (PROTECT), que estudia los factores de riesgo ambientales para el embarazo pre-término en mujeres embarazadas. Las participantes completaron un cuestionario de frecuencia alimentaria (FFQ) en las semanas 20-28 de gestación. Los niveles de hemoglobina, glucosa en sangre, presión arterial y edad gestacional se recogieron de expediente médicos. Posibles asociaciones entre factores dietéticos y las medidas del embarazo fueron evaluadas usando Ji cuadrado en SPSS. Un total de 180 participantes completaron el FFQ; 19,2% tuvo bajos niveles de hemoglobina, 21.1% tuvo niveles altos de glucemia por prueba de glucosa en ayunas y 24,6% por prueba de tolerancia a la glucosa de 1 hora; la hipertensión arterial fue encontrada en 2,9% (sistólica) y 6,5% (diastólica) y nacimiento prematuro fue encontrado en 10,4%. Un alto consumo de arroz, postres y dulces se asoció con mayores niveles de glucosa en ayunas (p<0,05), mientras que el alto consumo de vegetales se asoció con mayor nivel de la prueba de tolerancia a la glucosa (p<0,05). No se encontró ninguna otra asociación significativa. En conclusión, el consumo de alimentos de alta densidad energética en el embarazo como arroz, postres y dulces pueden elevar los niveles de glucosa en sangre, lo cual puede ser un predictor potencial de complicaciones en el embarazo en estas participantes, como diabetes gestacional.

Key plants preserve elements of culture: a study over distance and time of fresh crops in Puerto Rican markets in Hartford, Connecticut, "A moveable feast".

PREMISE OF THE STUDY: People retain culinary customs when they migrate. We tested this commitment via the study of Puerto Rican fresh produce markets in the continental United States over time, 18 yr, and space, by comparisons with source markets in Puerto Rico (PR). METHODS: A survey of Puerto Rican markets in Hartford (HT), Connecticut in 1993-1994 was repeated in 2009-2010. A comparative study was made at open-air markets in PR in 2009. Surveys recorded fresh crops, and interviews with vendors and Hartford Puerto Rican residents provided context. KEY RESULTS: We recorded 84 plant crops (64 species; 32 families) for seven categories. The largest category was viandas (fresh, starchy "root" crops and immature fruits), followed by saborizantes (flavorings). In the second HT survey, 80% of the crops were still present. And ∼90% of the HT 1993-1994 crops and ∼75% of the HT 2009-2010 crops were shared with markets in PR. CONCLUSIONS: On the basis of our results, we suggest two new concepts. The persistence of these largely tropical foods in a temperate market far removed from tropical PR shows the importance of basic foods as an element of cultural identification. We recognize this stability as an example of "culinary cultural conservation". Second, analysis of these fresh produce markets leads to the conclusion that viandas are the most prominent in diversity, persistence over time and distance, volume, and in terms of consumers' "willingness to pay". Accordingly, we consider the viandas a good example of a "cultural keystone food group", a food group that is emblematic of a community's culinary conservation.

Complementary and alternative medicine use and adherence to asthma medications among Latino and non-Latino white families.

OBJECTIVE: The current study sought to evaluate patterns of complementary and alternative medicine (CAM) use in a sample of Latino and non-Latino white (NLW) children with asthma to determine whether parental beliefs about conventional medications and barriers to obtaining these medications were related to CAM use and to assess whether CAM use was associated with decreased adherence to controller medications. METHODS: Participants included 574 families of children with asthma from NLW, Puerto Rican (PR), and Dominican backgrounds from Rhode Island (RI) and from Island PR. All parents completed a brief checklist of barriers to medication use and an assessment of CAM approaches. A subsample of 259 families had controller medication use monitored objectively for approximately 1 month by MDILog (fluticasone propionate), TrackCap (montelukast), or dosage counter (fluticasone/salmeterol combination). RESULTS: Prevalence of CAM use was high among Latino families. Perceived barriers to obtaining medication were related to increased CAM use in PR families from RI. Elevated medication concerns were positively associated with CAM use among NLW and Island PR families. CAM use was positively related to objective adherence within NLW families, and unrelated in other groups. CONCLUSIONS: CAM use is common among Latino families with asthma. Among some families, CAM use may be initiated as a way to cope with barriers to obtaining medication or when parents have concerns about conventional medications. Families who report CAM use do not appear to be substituting CAM for conventional asthma medication.

A review of barriers to effective asthma management in Puerto Ricans: cultural, healthcare system and pharmacogenomic issues.

BACKGROUND: Among the Hispanic community, Puerto Ricans have the highest prevalence of asthma and manifest the worst outcomes. The expected growth of the Hispanic population in the USA in the next several decades make elimination of disparate care in Puerto Rican asthmatics a matter of national importance. The purpose of this review of the literature (ROL) is to examine a variety of health system, genetic and cultural barriers in the Puerto Rican community which have created disparities in asthma care and outcomes among adult and pediatric Hispanic populations. In addition, this ROL describes several culturally sensitive, community-based educational interventions which can be used as a framework for future projects to improved asthma outcomes. METHODS: Databases searched included Medline, PubMED, EBSCOhost, PsycINFO, CINAHL, Google Scholar and ERIC. Papers published in English from January 1990 to January 2012 were reviewed. RESULTS: Health system policies, insurer compensation patterns, clinician attitudes and cultural values/folk remedies in the Puerto Rican community represent barriers to effective asthma management, the use of controller medication and the implementation of educational interventions. In addition, genetic factors involving the beta-2 adrenergic receptor gene, which impair the response to albuterol, appear to contribute to poorer outcomes in Puerto Rican asthmatics. In contrast, several comprehensive, community-based, culturally sensitive educational interventions such as Controlling Asthma in American Cities Project (CAACP), the Racial and Ethnic Approach to Community Health in the US Program and Healthy Hoops programs (REACH) have been described. CONCLUSIONS: We believe that culturally sensitive community-based asthma education programs can serve as models for programs targeted toward Puerto Ricans to help decrease asthma morbidity. Moreover, greater sensitivity to Puerto Rican mores and folk remedies on the part of healthcare providers may improve the patient-clinician rapport and, hence, asthma outcomes. Finally, given ethnically based differences in pharmacogenomics, clinical trials targeting the Puerto Rican population may help to better define optimal asthma medication regimens in this ethnic group.

Circulating 25-hydroxyvitamin D, IRS1 variant rs2943641, and insulin resistance: replication of a gene-nutrient interaction in 4 populations of different ancestries.

BACKGROUND: Associations of either insulin receptor substrate 1 (IRS1) variants or circulating 25-hydroxyvitamin D [25(OH)D] with type 2 diabetes (T2D) and insulin resistance (IR) are inconsistent. This study sought to determine whether circulating 25(OH)D modulates the association of a potentially functional variant at IRS1 (rs2943641) with insulin resistance. METHOD: Interaction between IRS1 rs2943641 and circulating 25(OH)D on homeostasis model assessment for IR (HOMA-IR) was examined in the Boston Puerto Rican Health Study (BPRHS) (n = 1144). Replication was performed in the African-American (n = 1126), non-Hispanic white (n = 1967), and Hispanic (n = 1241) populations of the Multi-Ethnic Study of Atherosclerosis (MESA) with genotypes of 3 IRS1 variants, rs2972144, rs1515104, and rs2673142, which are tag single nucleotide polymorphisms (SNPs) and in strong linkage disequilibrium with rs2943641. RESULTS: Higher circulating 25(OH)D was associated with lower risk of T2D and IR in BPRHS women homozygous for minor allele rs2943641T. Consistently, in each of 3 MESA populations, HOMA-IR and insulin decreased more evidently with higher circulating 25(OH)D in women of the rs2943641TT genotype than in carriers of the major allele (rs2943641C). Metaanalysis indicated significant and consistent interactions between circulating 25(OH)D and IRS1 variants on HOMA-IR (log transformed) [pooled ß = -0.008, 95% CI: -0.016 to -0.001, P interaction = 0.004] and insulin (log transformed) (pooled ß = -0.006, 95% CI: -0.011 to -0.002, P interaction = 0.023) in 3065 women of the 4 populations. CONCLUSIONS: Participants with different genotypes of IRS1 rs2943641 exhibit differential benefit from high circulating 25(OH)D for the reduction of insulin resistance and T2D risk. This gene-nutrient interaction, which appears to be limited to women, warrants further examination in randomized controlled trials of vitamin D supplementation.

Disparities in completion of substance abuse treatment among Latino subgroups in Los Angeles County, CA.

RATIONALE: A growing body of research has revealed disparities with respect to drug use patterns within Latino subgroups. However, the extent to which these potential disparities enable different Latino subgroups to respond favorably to treatment is unclear. METHODS: This study analyzed a subset of multicross-sectional data (2006-2009) on Latinos collected from publicly funded facilities in Los Angeles County, CA (N=12,871). We used multilevel logistic regressions to examine individual and service-level factors associated with treatment completion among subgroups of first-time Latino treatment clients. RESULTS: Univariate analysis showed that Cubans and Puerto Ricans were less likely to complete treatment than Mexicans and other Latinos. Cubans and Puerto Ricans entered treatment at an older age and with higher formal education than Mexicans, yet they were more likely to report mental health issues and use of cocaine and heroin as primary drugs of choice respectively. Multivariate analysis showed that age, having mental health issues, reporting high use of drugs at intake, and use of methamphetamines and marijuana were associated with decreased odds of completing treatment among all Latino subgroups. In contrast, age at first drug use, treatment duration, and referral monitoring by the criminal system increased the odds of completing treatment for all members. CONCLUSION: These findings have implications for targeting interventions for members of different Latinos groups during their first treatment episode. Promising individual and service factors associated with treatment completion can inform the design of culturally specific recovery models that can be evaluated in small-scale randomized pilot studies.

Knowledge and use of ethnomedical treatments for asthma among Puerto Ricans in an urban community.

PURPOSE: Puerto Ricans have higher lifetime and current asthma prevalence than other racial and ethnic groups in the United States. A great many Hispanics use ethnomedical therapies for asthma. This study elicited participant knowledge of ethnomedical therapies, developed a typology of the therapies, and considered whether some types are used or deemed efficacious based, in part, on information source. METHODS: Eligible participants were randomly selected from the medical records of an inner-city primary care clinic serving a predominantly Hispanic community in Buffalo, New York. Thirty adult Puerto Ricans who had asthma or were care-givers of children with asthma were interviewed in person using a semistructured instrument. Qualitative data analysis followed a content-driven immersion-crystallization approach. Outcome measures were ethnomedical treatments for asthma known to participants, whether these treatments were used or perceived effective, and the participant's information source about the treatment. RESULTS: Participants identified 75 ethnomedical treatments for asthma. Behavioral strategies were significantly more likely to be used or perceived effective compared with ingested and topical remedies (P <.001). Among information sources for ingested and topical remedies, those recommended by community members were significantly less likely to be used or perceived effective (P <.001) compared with other sources. CONCLUSIONS: This sample of Puerto Ricans with a regular source of medical care was significantly more likely to use or perceive as effective behavioral strategies compared with ingested and topical remedies. Allopathic clinicians should ask Puerto Rican patients about their use of ethnomedical therapies for asthma to better understand their health beliefs and to integrate ethnomedical therapies with allopathic medicine.

Dietary intake of vitamin B-6, plasma pyridoxal 5'-phosphate, and homocysteine in Puerto Rican adults.

BACKGROUND: Vitamin B-6 is an important cofactor in many metabolic processes. However, vitamin B-6 intake and plasma status have not been well studied in the Puerto Rican population, a group with documented health disparities. OBJECTIVE: To assess dietary intake of vitamin B-6, food sources, and plasma status of pyridoxal 5'-phosphate (PLP), and their associations with plasma homocysteine in 1,236 Puerto Rican adults, aged 45 to 75 years, living in the greater Boston area. DESIGN: Baseline data were analyzed cross-sectionally. METHOD: Questionnaire data were collected by home interview. Dietary intake was assessed with a semiquantitative food frequency questionnaire. Plasma PLP and homocysteine were assayed from blood samples collected in the home. RESULTS: The mean daily intake of vitamin B-6 was 2.90 ± 1.28 mg for men and 2.61 ± 1.29 mg for women (P<0.001). Approximately 11% were deficient (PLP <4.94 ng/mL [PLP <20 nmol/L]) and another 17% insufficient (PLP ≥ 4.94 but <7.41 ng/mL [PLP ≥ 20 but <30 nmol/L]). Household income below the poverty threshold, physical inactivity, and current smoking were significantly associated with lower plasma PLP (P<0.05). Food groups contributing most to vitamin B-6 intake included ready-to-eat cereals, poultry, rice, potatoes, and dried beans. However, only intake of ready-to-eat cereals and use of supplements with vitamin B-6 were significantly associated with plasma PLP sufficiency (≥ 7.41 vs <7.41 ng/mL [PLP ≥ 30 vs <30 nmol/L], P<0.01). Both vitamin B-6 intake and PLP were significantly associated with plasma total homocysteine (P<0.001). The association between PLP and homocysteine remained statistically significant after further adjustment for plasma vitamin B-12 and folate (P=0.028). CONCLUSIONS: Given the known importance of vitamin B-6 to health, the high prevalence of low vitamin B-6 status in this Puerto Rican population is of concern. Further work is needed to clarify the potential role that insufficient vitamin B-6 may have in relation to the observed health disparities in this population.

Adherence to an (n-3) fatty acid/fish intake pattern is inversely associated with metabolic syndrome among Puerto Rican adults in the Greater Boston area.

Combinations of fatty acids may affect risk of metabolic syndrome. Puerto Ricans have a disproportionate number of chronic conditions compared with other Hispanic groups. We aimed to characterize fatty acid intake patterns of Puerto Rican adults aged 45-75 y and living in the Greater Boston area (n = 1207) and to examine associations between these patterns and metabolic syndrome. Dietary fatty acids, as a percentage of total fat, were entered into principle components analysis. Spearman correlation coefficients were used to examine associations between fatty acid intake patterns, nutrients, and food groups. Associations with metabolic syndrome were analyzed by using logistic regression and general linear models with quintiles of principal component scores. Four principal components (factors) emerged: factor 1, short- and medium-chain SFA/dairy; factor 2, (n-3) fatty acid/fish; factor 3, very long-chain (VLC) SFA and PUFA/oils; and factor 4, monounsaturated fatty acid/trans fat. The SFA/dairy factor was inversely associated with fasting serum glucose concentrations (P = 0.02) and the VLC SFA/oils factor was negatively related to waist circumference (P = 0.008). However, these associations were no longer significant after additional adjustment for BMI. The (n-3) fatty acid/fish factor was associated with a lower likelihood of metabolic syndrome (Q5 vs. Q1: odds ratio: 0.54, 95% CI: 0.34, 0.86). In summary, principal components analysis of fatty acid intakes revealed 4 dietary fatty acid patterns in this population. Identifying optimal combinations of fatty acids may be beneficial for understanding relationships with health outcomes given their diverse effects on metabolism.

Spirituality, coping, and HIV risk and prevention in a sample of severely mentally ill Puerto Rican women.

Hispanics have been disproportionately impacted by HIV/AIDS. Although HIV risk is significantly elevated among severely mentally ill persons (SMI), the risk of infection appears to be even greater among those SMI who are Hispanic, reflecting the increased risk of HIV among Hispanics. We report on findings from the first 41 participants in a qualitative study examining the context of HIV risk and risk reduction strategies among severely mentally ill Puerto Rican women residents in northeastern Ohio. Individuals participated in a baseline interview, two follow-up interviews, and up to 100 hours of shadowing. Interviews and shadowing activities were recorded and analyzed using a grounded theory. The majority of individuals reported using identification with a religious faith. A large proportion of the participants reported that their religious or spiritual beliefs were critical to their coping, had influenced them to reduce risk, and/or provided them with needed social support. Several participants also reported having experienced rejection from their faith communities. The emphasis on spirituality among Puerto Rican SMI is consistent with previous research demonstrating the importance of spirituality in the Hispanic culture and reliance on spiritual beliefs as a mean of coping among SMI. Our results support the incorporation of spiritual beliefs into secular HIV prevention efforts.

Spirituality among Latinas/os: implications of culture in conceptualization and measurement.

Despite growing transnational migration between the United States and Latin American countries, culturally relevant conceptualizations of spirituality among Latinas/os remain lacking in healthcare research. Grounded in Latina feminist theology, this article elucidates cultural values that influence spirituality and describes findings from a study using a new questionnaire to explore spirituality among Latinas in Puerto Rico and the US mainland. Results support the saliency of cultural values such as personalismo and familismo as the context for spiritual perspectives, which may function independently of the Catholic Church structure.
