RESUMO

BACKGROUND: Vitamin K (VK) exists in the form of phylloquinone (PK) and menaquinones (MKs). Roles of VK on cognitive health in the elderly are emerging, but there is limited evidence on VK uptake and metabolism in human brain. OBJECTIVES: The primary objective of this study was to characterize VK distribution in brains of an elderly population with varied cognitive function. In addition, associations among circulating (a biomarker of VK intake) and cerebral VK concentrations and cognition were investigated. METHODS: Serum or plasma (n = 27) and brain samples from the frontal cortex (FC; n = 46) and the temporal cortex (TC; n = 33) were acquired from 48 decedents (aged 98-107 y; 25 demented and 23 nondemented) enrolled in the Georgia Centenarian Study. Both circulating and brain VK concentrations were measured using HPLC with fluorescence detection. Cognitive assessment was performed within 1 y prior to mortality. Partial correlations between serum/plasma or cerebral VK concentrations and cognitive function were performed, adjusting for covariates and separating by dementia and antithrombotic use. RESULTS: MK-4 was the predominant vitamer in both FC (mean ± SD = 4.92 ± 2.31 pmol/g, ≥89.15% ± 5.09% of total VK) and TC (4.60 ± 2.11 pmol/g, ≥89.71% ± 4.43% of total VK) regardless of cognitive status. Antithrombotic users had 34.0% and 53.9% lower MK-4 concentrations in FC (P < 0.05) and TC (P < 0.001), respectively. Circulating PK was not correlated with cerebral MK-4 or total VK concentrations. Circulating PK concentrations were significantly associated with a wide range of cognitive measures in nondemented centenarians (P < 0.05). In contrast, cerebral MK-4 concentrations were not associated with cognitive performance, either before or after exclusion of antithrombotic users. CONCLUSIONS: Circulating VK concentrations are not related to cerebral MK-4 concentrations in centenarians. Cerebral MK-4 concentrations are tightly regulated over a range of VK intakes and cognitive function. Circulating PK may reflect intake of VK-rich foods containing other dietary components beneficial to cognitive health. Further investigation of VK uptake and metabolism in the brain is warranted.

RESUMO

PURPOSE: While including amorphous solid dispersion (ASD) in tablet formulations is increasingly common, tablets containing high ASD loading are associated with slow disintegration, which presents a challenge to control pill burden for less potent compounds. METHODS: We use a model ASD, composed of a hydrophobic drug with copovidone and a non-ionic surfactant, to explore formulation options that can prevent slow disintegration. RESULTS: In addition to the ASD loading, the pH of the disintegration medium and the inclusion of inorganic salts in the tablet also have an impact on the tablet disintegration time. Certain kosmotropic salts, when added in the formulation, can significantly accelerate tablet disintegration, though the rank order in their effectiveness does not exactly follow the Hofmeister series at pH 1.8. The particle size and dissolution rate of the salt can contribute to its overall effectiveness. CONCLUSION: We provided a mechanistic explanation of the disintegration process: fast-dissolving kosmotropic salt results in a concentrated salt solution inside the restrained tablet matrix, thus inhibiting the dissolution of copovidone and preventing polymer gelling which is the main cause leading the slow disintegration. The outcome of this study has enabled the design of a higher ASD loading platform formulation for copovidone based ASD. Graphical Abstract MicroCT aids the mechanistic understanding of the role of inorganic salt in the tablet disintegration of amorphous solid dispersion based formulation.

RESUMO

BACKGROUND: Oesophageal perforation is a life-threatening condition that requires urgent intervention. Surgical repair is recommended within 24 h of onset to minimise mortality risk, traditionally via an open thoracotomy or a laparotomy. Primary oesophageal repair via a laparoscopic trans-hiatal approach has been seldomly reported due to concerns of inadequate eradication of soilage in the mediastinum and pleural space, as well as poor access and an increased operative time in an unwell population. CASE PRESENTATION: We report a case series of 3 oesophageal and junctional perforations with varying presentations, demonstrating how the laparoscopic trans-hiatal approach can be used successfully to manage oesophageal perforations. CONCLUSIONS: Laparoscopic trans-hiatal repair is an attractive option for oesophageal and junctional perforations, in haemodynamically stable surgical candidates, in the absence of gross contamination of the thoracic cavity.

RESUMO

We present a case of chylous ascites in a 69-year-old man 5 months after a laparoscopic Toupet fundoplication (posterior 270°). This was successfully treated with laparoscopic ligation of tissue adjacent to the right crus. Laparoscopic ligation is a management option that should be considered after this rare complication, offering rapid results.

RESUMO

ABSTRACTObjectives:Centenarians have survived into very late life, but whether they reach very old age in good health remains unclear. The purpose of this study was to compare the cardiovascular health status and cognitive functioning of centenarians in the United States with centenarians in Japan. DESIGN, SETTING, AND PARTICIPANTS: This cross-national design compared centenarians from the United States and Japan. The sample of U.S. centenarians was recruited from the Georgia Centenarian Study and included 287 centenarians. The sample of Japanese centenarians was recruited from the Tokyo Centenarian Study and included 304 centenarians. MEASUREMENTS: Cognitive functioning was assessed with a mental status questionnaire, and cardiovascular disease by a health history assessment, blood pressure, and selected blood parameters. RESULTS: The results suggest that Tokyo centenarians had lower disease experiences and BMI values, when compared to Georgia centenarians, but blood pressure was higher among Japanese centenarians. Lower levels of hemoglobin in Japanese centenarians and higher levels of C-reactive protein in Georgia were also found. The positive association of hypertension and albumin levels with cognitive functioning and the negative association of stroke occurrence with cognitive functioning were replicated in both countries. Differential effects were obtained for heart problems, BMI, and C-reactive protein (with positive effects for Tokyo centenarians, except for C-reactive protein). CONCLUSION: For extremely old individuals, some markers of cardiovascular disease are replicable across countries, whereas differential effects for cardiovascular health also need to be considered in cardiovascular health.

RESUMO

OBJECTIVE: The present study examined the cultural differences and similarities in the levels and predictors of subjective well-being in Japanese and American centenarians. METHOD: We analyzed data on cognitively intact Japanese (N = 59) and American (N = 125) participants from the Tokyo and Georgia Centenarian Studies, respectively. The Philadelphia Geriatric Center Morale Scale was used to measure subjective well-being, while sociodemographic, social, and health resources were assessed as potential predictors. RESULTS: The American participants reported higher scores on well-being (satisfaction with social relations and psychological comfort). However, cultural differences in the levels of well-being disappeared after we controlled for its predictors. The regression models revealed that health resources (cognitive function, hearing problems, and activities of daily living) were strong predictors of well-being in both countries. Social resources (living with others) were strongly associated with one dimension of well-being (attitude toward one's aging) among the Japanese participants. DISCUSSION: The findings support the existing lifespan and cross-cultural literature, indicating that declines in health impose certain limitations on adaptive capacity in oldest-old age irrespective of cultures, and that social embeddedness is valued in Eastern cultures. The authors speculate that cultural values, i.e. personal autonomy versus relational harmony, play an important role for well-being in oldest-old age.

RESUMO

BACKGROUND: Nonmelanoma skin cancers rarely arise from venous leg ulcers (VLUs). Although basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer, its association with lower-extremity ulcers is not as frequently reported as other malignancies. OBJECTIVE: To report a case series of biopsy-proven BCC from lower-extremity ulcers of patients who presented at a multispecialty wound clinic. METHODS: Four male patients (mean age, 82.75 years) with 4 chronic VLUs (duration ranging from 2 months to 10 years) underwent a biopsy of their ulcerative lesions. RESULTS: Histologic examination of the specimens revealed 4 cases of BCC. All of the lesions were surgically excised, followed by split-thickness skin graft (n = 2) or healing by secondary intention (n = 2). All of the patients remained healed at follow-up ranging from 15 to 27 months, except for 1 patient who opted for conservative management and had not completely healed at 14 months' follow-up. CONCLUSIONS: Biopsies are warranted for any VLU with documented stalled healing following 3 months of standard of care. One biopsy is performed at the periphery of the ulcer and another at the base in order to rule out the presence of malignant transformation because of BCC, squamous cell carcinoma, sarcoma, melanoma, lymphoma, or metastases.

RESUMO

BACKGROUND: Atopic dermatitis (AD) is a chronic disease requiring regular follow-up. To increase access to dermatological care, online management of AD is being studied. However, a critical knowledge gap exists in determining AD patients' quality of life in direct-to-patient online models. In this study, we examined quality of life in AD patients managed through a direct-access online model. MATERIALS AND METHODS: We randomized 156 patients to receiving care through a direct-access online platform or in person. Patients were seen for six visits over 12 months. At each visit, the patients completed Dermatology Life Quality Index/Children's Dermatology Life Quality Index (DLQI/CDLQI), and Short Form (SF-12). RESULTS: Between baseline and 12 months, the mean (standard deviation, SD) within-group difference in DLQI score in the online group was 4.1 (±2.3); for the in-person group, the within-group difference was 4.8 (±2.7). The mean (SD) within-group difference in CDLQI score in the online group was 4.7 (±2.8); for the in-person group, the within-group difference was 4.9 (±3.1). The mean (SD) within-group difference in physical component score (PCS) and mental component score (MCS) SF-12 scores in the online group was 6.5 (±3.8) and 8.6 (±4.3); for the in-person group, it was 6.8 (±3.2) and 9.1(±3.8), respectively. The difference in the change in DLQI, CDLQI, SF-12 PCS, and SF-12 MCS scores between the two groups was 0.72 (95% confidence interval [90% CI], -0.97 to 2.41), 0.23 (90% CI, -2.21 to 2.67), 0.34 (90% CI, -1.16 to 1.84), and 0.51 (90% CI, -1.11 to 2.13), respectively. All differences were contained within their equivalence margins. CONCLUSION: Adult and pediatric AD patients receiving direct-access online care had equivalent quality of life outcomes as those see in person. The direct-access online model has the potential to increase access to care for patients with chronic skin diseases.

RESUMO

BACKGROUND/AIMS: Limited data are available regarding the undergraduate dermatology clinical clerkship curriculum in the United States. Our primaryaim is to assess medical students' perspectives of the dermatology clinical clerkship. METHODS: A multicenter survey study was conducted, which included four California dermatology academic programs. A 17-item questionnaire was designed to investigate medical student perception with regard tothe overall educational value of the various teaching aspects of the dermatology clinical clerkship. RESULTS: A total of 152 medical student surveys were completed. Over half of the medical students felt proficient in diagnosing the most commondermatologic conditions. Eighty-seven percent of medical students were very satisfied with the dermatology clerkship. Ninety-one percent of students felt the length of the clerkship was appropriate. CONCLUSIONS: The vast majority of medical students reported a high level of proficiency in the treatment and diagnosis of common skin disorders. In contrast, our findings suggest that medical students may not begaining sufficient hands-on experience in conducting certain dermatologic procedures following the dermatology clerkship. Overall, medical studentperception of the dermatology clinical clerkship was mostly positive.

RESUMO

OBJECTIVE: As the population ages, osteoporosis is a growing global public health problem. This study examined potential risk factors associated with osteoporosis in a nationally representative sample of Korean postmenopausal women. METHODS: This study used data from a nationally representative sample of Korean menopausal women participating in the Korea National Health and Nutrition Examination Survey KNHANES 2009 (n = 1467; mean age ± SE = 65.2 ± 0.3 years). Bone mineral density of total femur, femoral neck, and spine was measured by dual-energy X-ray absorptiometry. Osteoporosis was determined as t-score of -2.5 or below in at least 1 of the 3 sites. Menopausal status was confirmed by self-reports. RESULTS: About 41% of the study sample met the criteria for osteoporosis. Poor socioeconomic status, lower BMI, and shorter estrogen exposure duration were significantly associated with osteoporosis in the study sample. Poor dietary intake was also related to osteoporosis. In the age- and energy-adjusted logistic regression models, participants consuming less protein, vitamin B2, or vitamin C than the estimated average requirement (EAR) showed higher odds of having osteoporosis than their counterparts. Participants consuming no milk or milk products had 45% increased odds of having osteoporosis than those consuming milk or milk products. CONCLUSION: The findings of this study suggest several risk factors associated with osteoporosis, which can be addressed in the development and implementation of tailored nutritional interventions to promote the bone health of Korean postmenopausal women.

RESUMO

IMPORTANCE: Granuloma annulare is typically a benign, self-limited disease. Atypical presentations have been reported in association with systemic disease, including malignancy. Such patients may require additional diagnostic studies to assess for underlying malignancy. We report a patient with extensive sporotrichoid granuloma annulare-like dermatitis in association with systemic B-cell lymphoma. OBSERVATIONS: An 83-year-old man with a three-year history of progressive sporotrichoid annular plaques and nodules on the arm developed ipsilateral retroauricular palpable lymphadenopathy, the latter consistent with B-cell lymphoma. Multiple skin biopsies of the plaques and nodules revealed granuloma annulare-like dermatitis. Lesions were unresponsive to intralesional and intramuscular corticosteroids, antibiotics, and antifungal agents, but rapidly improved following initiation of rituximab to treat his underlying lymphoma. CONCLUSIONS AND RELEVANCE: Atypical presentations of granuloma annulare including granuloma annulare-like dermatitis warrant evaluation for systemic malignancy in a subset of patients.

RESUMO

OBJECTIVES: The purpose of this study was to assess the relationship between apolipoprotein E (APOE), life events and engagement, and subjective well-being (as measured by positive and negative affect) among centenarians. Based on the life stress paradigm, we predicted that higher levels of stress would allow APOE to influence positive and negative affect. METHOD: 196 centenarians and near-centenarians (98 years and older) of the Georgia Centenarian Study participated in this research. The APOE, positive and negative affect, the number of recent (last 2 years) and lifelong (more than 20 years prior to testing) events, as well as a number of life engagement tasks were assessed. RESULTS: Results suggested that centenarians carrying the APOE ϵ4 allele rated lower in positive affect, the number of lifelong events, and in engaged lifestyle, when compared to centenarians without the APOE ϵ4 allele (t = 3.43, p < .01; t = 3.19, p < .01; and t = 2.33, p < .05, respectively). Blockwise multiple regressions indicated that the APOE ϵ4 predicted positive but not negative affect after controlling for demographics. Gene-environment interactions were obtained for the APOE ϵ4 and lifelong events, suggesting that carriers of the APOE ϵ4 allele had higher scores of negative affect after having experienced more events, whereas noncarriers had reduced negative affect levels after having experienced more events. CONCLUSION: APOE ϵ4 is directly related to positive affect and is related to negative affect in interaction with life events.

RESUMO

Brain alpha-tocopherol (αT) concentration was previously reported to be inversely associated with neurofibrillary tangle (NFT) counts in specific brain structures from centenarians. However, the contribution of natural or synthetic αT stereoisomers to this relationship is unknown. In this study, αT stereoisomers were quantified in the temporal cortex (TC) of 47 centenarians in the Georgia Centenarian Study (age: 102.2 ± 2.5 years, BMI: 22.1 ± 3.9 kg/m2) and then correlated with amyloid plaques (diffuse and neuritic plaques; DPs, NPs) and NFTs in seven brain regions. The natural stereoisomer, RRR-αT, was the primary stereoisomer in all subjects, accounting for >50% of total αT in all but five subjects. %RRR was inversely correlated with DPs in the frontal cortex (FC) (ρ = -0.35, p = 0.032) and TC (ρ = -0.34, p = 0.038). %RSS (a synthetic αT stereoisomer) was positively correlated with DPs in the TC (ρ = 0.39, p = 0.017) and with NFTs in the FC (ρ = 0.37, p = 0.024), TC (ρ = 0.42, p = 0.009), and amygdala (ρ = 0.43, p = 0.008) after controlling for covariates. Neither RRR- nor RSS-αT were associated with premortem global cognition. Even with the narrow and normal range of BMIs, BMI was correlated with %RRR-αT (ρ = 0.34, p = 0.021) and %RSS-αT (ρ = -0.45, p = 0.002). These results providing the first characterization of TC αT stereoisomer profiles in centenarians suggest that DP and NFT counts, but not premortem global cognition, are influenced by the brain accumulation of specific αT stereoisomers. Further study is needed to confirm these findings and to determine the potential role of BMI in mediating this relationship.

RESUMO

UNLABELLED: BACKGROUND/STUDY CONTEXT: The goal of the study was to identify and characterize latent profiles (clusters) of cognitive functioning in centenarians and the psychometric properties of cognitive measures within them. METHODS: Data were collected from cross-sectional, population-based sample of 244 centenarians (aged 98 to 108, 15.8% men, 20.5% African American, 38.0% community-dwelling) from 44 counties in northern Georgia participating in the Georgia Centenarian Study (2001-2008). Measures included the Mini-Mental State Examination (MMSE), Severe Impairment Battery (SIB), Wechsler Adult Intelligence Scale-III Similarities subtest (WAIS), Hand Tapping, Behavioral Dyscontrol Scale (BDS), Controlled Oral Word Association Test (COWAT), and Fuld Object Memory Evaluation (FOME). The Global Deterioration Rating Scale (GDRS) was used to independently evaluate criterion-related validity for distinguishing cognitively normal and impaired groups. Relevant covariates included directly assessed functional status for basic and instrumental activities of daily living (DAFS), race, gender, educational attainment, Geriatric Depression Scale Short Form (GDS), and vision and hearing problems. RESULTS: Results suggest two distinct classes of cognitive performance in this centenarian sample. Approximately one third of the centenarians show a pattern of markedly lower cognitive performance on most measures. Group membership is independently well predicted (area under the curve [AUC] = .83) by GDRS scores (sensitivity 67.7%, specificity 82.4%). Membership in the lower cognitive performance group was more likely for individuals who were older, African Americans, had more depressive symptoms, lower plasma folate, carriers of the apolipoprotein E (APOE) ε4 allele, facility residents, and individuals who died in the 2 years following interview. CONCLUSIONS: In a population expected to have high prevalence of dementia, latent subtypes can be distinguished via factor mixture analysis that provide normative values for cognitive functioning. The present study allows estimates for normative cognitive performance in this age group.

RESUMO

Background: Post-operative complications are the main contributing factor to increased length of stay, increased cost of care and short-term mortality experienced by patients following gastrectomy. The purpose of this study was to determine the diagnostic accuracy of C-reactive protein (CRP) in predicting complications following gastrectomy. This may assist clinicians to make better informed clinical decisions in the post-operative period. Methods: A retrospective analysis of a prospectively maintained database was performed. Sixty patients who underwent gastrectomy for gastric cancer were included. Demographic information, operative data and post-operative details such as complications, unplanned intensive care unit (ICU) admission and readmission to hospital were analysed. Complications were further analysed based on whether they were either infective or non-infective in nature. Receiver operator characteristic (ROC) analysis was performed to examine the association between CRP and post-operative morbidity. Optimum cut-offs were determined using the Youden's index. Results: From the second post-operative day (POD), CRP levels were able to predict subsequent severe infective (SI) complications following gastrectomy [area under the curve (AUC): 0.789, 95% CI : 0.636-0.941]. An optimum cut-off of 180 mg/L resulted in a sensitivity of 87.50%. The negative predictive value (NPV) at this point was 96.30%. Conclusions: CRP is a strong negative predicter of SI complications following gastrectomy. This suggests early CRP values may be useful in prompting early investigation or facilitating safer, earlier discharge from hospital. Health services may benefit by determining similar cut-offs based on their own unique patient populations.

RESUMO

Low 25-hydroxyvitamin D (25(OH)D) concentrations are common among older adults and are associated with poorer physical performance and strength, but results from longitudinal studies have been inconsistent. The 25(OH)D threshold for physical performance and strength was determined, and both cross-sectional and longitudinal associations between 25(OH)D and physical performance and strength were examined, in men and women aged 71-80 years from the Health, Aging, and Body Composition Study (n = 2,641). Baseline serum 25(OH)D was measured in 1998-1999, and physical performance and strength were measured at baseline and at 2- and 4-year follow-up. Piecewise regression models were used to determine 25(OH)D thresholds. Linear regression and mixed models were used to examine cross-sectional and longitudinal associations. The 25(OH)D thresholds were 70-80 nmol/L for physical performance and 55-70 nmol/L for strength. Participants with 25(OH)D <50 nmol/L had poorer physical performance at baseline and at 2- and 4-year follow-up than participants with 25(OH)D ≥75 nmol/L (P < 0.01). Although physical performance and strength declined over 4 years of follow-up (P < 0.0001), in general, the rate of decline was not associated with baseline 25(OH)D. Older adults with low 25(OH)D concentrations had poorer physical performance over 4 years of follow-up, but low 25(OH)D concentrations were not associated with a faster rate of decline in physical performance or strength.

RESUMO

Food insecurity is a persistent, growing, and clinically relevant problem in older adults; however, its effect on healthcare expenditures is not known. This study examined the relationship of food insecurity with Medicare and out-of-pocket expenditures in older Georgians enrolled in Medicare and meal services using 2 complementary datasets: Georgia Advanced Performance Outcomes Measures Project 6 (GA Advanced POMP6) and Medicare claims data in 2008 (n = 903, mean age 76.9 ± 7.8 y, 31.0% male, 64.2% white). Due to the mixed distribution of healthcare expenditure data (e.g., high nonusers, right-skewed distribution for users), 2-part models were used. Approximately one-half of the sample was food insecure (50.4%) and was more likely to report poorer health status and to have chronic diseases than food-insecure individuals. Food-insecure older adults were less likely to have any Medicare expenditure than food-secure older adults. Among those who had positive Medicare expenditure, however, food-insecure and food-secure individuals had similar Medicare expenditures. Food-insecure and food-secure older individuals were equally likely to incur out-of-pocket expenditure. However, among those who had positive out-of-pocket expenditure, food-insecure older individuals had lower out-of-pocket expenditures than their counterparts. Adjusted mean Medicare and out-of-pocket expenditures of food-insecure individuals were $1875 and $310 less than food-secure individuals in 2008, respectively. These findings based on the innovative methodological approaches and datasets suggest complex relationships between food insecurity and healthcare expenditures in older adults, reflecting unique healthcare access and usage patterns.

RESUMO

BACKGROUND: Fatigue is a common and frequently observed complaint among older adults. However, knowledge about the nature and correlates of fatigue in old age is very limited. OBJECTIVE: This study examined the relationship of functional indicators, psychological and situational factors and fatigue for 210 octogenarians and centenarians from the Georgia Centenarian Study. METHODS: Three indicators of functional capacity (self-rated health, instrumental activities of daily living, physical activities of daily living), two indicators of psychological well-being (positive and negative affect), two indicators of situational factors (social network and social support), and a multidimensional fatigue scale were used. Blocked multiple regression analyses were computed to examine significant factors related to fatigue. In addition, multi-group analysis in structural equation modeling was used to investigate residential differences (i.e., long-term care facilities vs. private homes) in the relationship between significant factors and fatigue. RESULTS: Blocked multiple regression analyses indicated that two indicators of functional capacity, self-rated health and instrumental activities of daily living, both positive and negative affect, and social support were significant predictors of fatigue among oldest-old adults. The multiple group analysis in structural equation modeling revealed a significant difference among oldest-old adults based on residential status. CONCLUSION: The results suggest that we should not consider fatigue as merely an unpleasant physical symptom, but rather adopt a perspective that different factors such as psychosocial aspects can influence fatigue in advanced later life.

RESUMO

Oesophageal neuroendocrine neoplasms (NENs) are rare tumours. Neuroendocrine carcinomas (NECs) are the highest grade of NENs, with aggressive biological behaviour and poor outcomes. No standardized treatment pathways exist for these tumours, with management being individualized based on patient and tumour factors. We present five cases, four men and one women between 63 and 68 years old, who were diagnosed with symptomatic primary oesophageal NECs. Three were diagnosed with localized disease, and two were diagnosed with metastatic disease. Endoscopy, biopsy and staging scan results are outlined. Two patients received neoadjuvant chemotherapy. Three patients with localized disease underwent oesophagectomy. Two of these patients received neoadjuvant chemotherapy. Four patients have succumbed to their disease, with a median survival following a diagnosis of 18 months (5-34 months). This case series highlights the variability of presentation and stage at diagnosis of oesophageal NECs. Multimodal treatment is commonly utilized; however, outcomes are universally poor. Further research is required to determine the optimal treatment regimen for oesophageal NENS.

RESUMO

Folic acid can prevent neural tube defects (NTD). Hispanic women have a higher prevalence of NTD than non-Hispanic white (NHW) women and consume less folic acid. Among Hispanics, acculturation has been associated with lower intakes of natural folate. It is unknown if this same relationship is seen for fortified foods. This article describes the associations of acculturation factors with usual folate intakes from foods and supplements and compares the proportion that meets recommended intakes of folic acid of US Mexican American (MA) women with those of NHW women. For US NHW and MA women aged 15-44 y (n = 3167), usual folate intakes (i.e., natural food folate, folic acid from food, total folic acid [fortified foods plus supplements], and total folate) were estimated using measurement error models from NHANES 2001-2008. Compared with NHW women, MA women did not differ in their intake of natural food folate or folic acid from food. Similarly, compared with NHW women (332 ± 17.3 µg/d), the mean total usual folic acid intakes were lower among MA women who reported speaking Spanish (224 ± 24.9 µg/d) but not for MA women who reported speaking English (283 ± 36.2 µg/d). MA women were more likely than NHW women to consume a total folic acid intake <400 µg/d. MA women with lower acculturation factors were the most likely to have an intake <400 µg/d compared to NHW women. Public health efforts should focus on increasing total folic acid intake among MA women, emphasizing those with lower acculturation factors (e.g., MA women who report speaking Spanish).
