Factors associated with chronic obstructive pulmonary disease (COPD) among never-smokers have received little research attention. One potential risk factor for COPD is obesity, which is of particular importance in light of the global obesity epidemic. The objective of this study was to investigate the association between COPD and levels of obesity in a nationally representative sample of non-Hispanic white never-smokers. Data were drawn from the 2012 Center for Disease Control’s Behavioral Risk Factor Surveillance System (BRFSS). Pearson’s chi-square tests and logistic regression analyses were conducted in a large nationally representative sample of non-Hispanic white respondents aged 50 and over (76,004 women; 37,618 men) who reported that they had never smoked. A dose-response relationship was observed for both men and women: the prevalence of COPD increased from 2.5% in men and 3.5% in women who were of a healthy weight (BMI < 25) to 7.6% in men and 13.4% in women who had a BMI of 40 or higher. Even after adjusting for 7 potential confounds (e.g., age, education, and income), the odds of COPD were 3.21 higher for men (95% CI = 2.46, 4.20) and 4.00 higher for women with class III obesity (95% CI = 3.52, 4.55) in comparison with those of healthy weight. Regular screening for COPD is warranted in never-smoking obese patients who are aged 50 and over. Future research is needed to investigate plausible mechanisms for this association, including (1) the role of chronic inflammation associated with obesity and (2) the impact of central obesity on respiratory system mechanics.

Abstract Introduction Sleep hygiene recommendations discourage eating close to bedtime, though published data on the impact are not consistent. Associations between eating or drinking, within 1-hour prior to bedtime, sleep duration and sleep fragmentation were examined in a nationally-representative sample. Methods Data from the American Time Use Survey (ATUS), administered to a nationally representative sample of n=201,151 US residents aged ≥15 years were utilized. In an annual phone interview, ATUS participants were asked to record their activities during a 24-hour period (04:00am to 04:00am on the interview day) and were randomly selected to report weekdays or weekend activities. The present analysis included data from 2003–2018 and restricted to weekday respondents (n=124,242). Reporting of eating/drinking activities within 1-hour prior to bedtime was considered as a dichotomous variable (yes/no). Sleep fragmentation was defined as any awakening during the primary sleep episode (yes/no). Linear and logistic regression models, adjusted for age, sex, cohabitation, education and employment, were used to examine associations between eating/drinking and sleep duration or sleep fragmentation. Results In this ATUS sample, 56% of respondents were female and the mean age was 45 years. Mean sleep duration was 8.02 (0.007) hours, and 6% of survey participants ate/drank within 1-hour prior to bedtime. Overall, eating/drinking within 1-hour prior to bedtime was associated with longer sleep duration (p&lt;0.01). Women and men who ate/drank within 1-hour prior to bedtime, in comparison to those who did not, had 35 minutes and 26 minutes longer sleep duration (p- value&lt;0.0001) Eating/drinking activities within 1-hour prior to bedtime were associated with 1.8 higher odds of fragmented sleep (p&lt;0.001). Conclusion In this large population-based survey, weekday eating or drinking within 1-hour prior to bedtime was associated with sleep fragmentation and longer sleep duration. Causal pathways would be difficult to discern, though sleep fragmentation could lead to compensatory increases in sleep duration. Support None

The Impact

The literature on factors that influence participation in qualitative research is lacking. We conducted an experiment with a nationally representative sample to test the impact of different incentive types and amounts on willingness to participate in a hypothetical qualitative interview. We randomized participants from an online panel to one of the five versions of a recruitment ad: no incentive, a nonmonetary incentive, US$25, US$50, or US$75 ( N = 4,136). All three monetary incentives resulted in greater willingness to participate than no incentive or a nonmonetary incentive. No differences emerged between no incentive and a nonmonetary incentive (drawing for noncash prize). Among those who had at least some willingness, US$75 produced more willingness than US$25. The US$50 and US$75 amounts did not differ. Results suggest incentives matter in achieving participation in qualitative research, but there may be diminishing returns. Nonmonetary incentives may not result in higher participation than no incentive at all.

The Impact

Background. We investigated the impact of widowhood on depression and how resources and contextual factors that define the meaning of loss modified this effect.Method. In a prospective, nationally representative sample of women in the US aged 54 or older we compared 64 women who were widowed in the 3 years between data collection waves with 431 women who were stably married over the time interval.Results. Those who became widowed reported more depression than controls for 2 years following the loss. However, this effect was confined to respondents whose husbands were not ill at baseline. Widowed women whose husbands were ill at baseline already had elevated depression in the baseline interview and did not become significantly more depressed after the death. Consistent with this result, women who were not depressed pre-bereavement were most vulnerable to depression following the loss of an ill spouse during the first year of widowhood.Conclusions. Results suggest that spouses' illness may forewarn wives of their impending loss and these women may begin to grieve before his death. Those forewarned women who are not depressed pre-bereavement may experience the most post-bereavement depression. Findings are discussed in light of previous, more methodologically limited studies.

The demographic situation has recently become one of the most important issues in modern Russia, which also affected the market of higher education service. The research objective was to analyze the demographic profile of Russia and the Kemerovo region. The author identified the impact of demographic and economic factors on the demand for higher education. A correlation analysis made it possible to select proper indicators in order to assess the impact of demographic and economic factors on the contingent of university students. The demographic factors included birth rate and the number of population aged 15–19. The economic factors were the average annual nominal salary and the average annual cost of education. The research revealed a positive correlation between the number of births, the amount of population aged 15–19, and the number of students in higher education institutions. Comparative and relative analyses made it possible to assess the paying capacity of population in the sphere of chargeable educational services, which showed an increase in the burden on the household budget and an increase in financial barriers to higher education. The research contributes to the development of the regional economy as it helps to predict the population's demand for higher education services.

Abstract BACKGROUND 24,25-Dihydroxyvitamin D [24,25(OH)2D] in serum may be both a nuisance and nutritionally valuable. METHODS We investigated the impact of 24,25(OH)2D3 on the performance of commercially available immunoassays for serum total 25-hydroxyvitamin D [25(OH)D] using (a) serum from a nationally representative sample of adults, (b) serum from a spiking experiment, and (c) data from the UK Vitamin D External Quality Assurance Scheme (DEQAS). We also investigated the utility of the serum ratio of 24,25(OH)2D3 to 25(OH)D as an index of inactivation and of response to vitamin D supplementation using randomized controlled trial (RCT) data. Measurement of 24,25(OH)2D in sera by a LC-MS/MS method allowed for an investigation of its impact on immunoassay-derived serum 25(OH)D values as well as its clinical utility. We report data from a nationally representative sample of adults, a recent vitamin D RCT in older adults, and DEQAS. RESULTS 24,25(OH)2D3 contributed to the positive bias observed in some immunoassays relative to LC-MS/MS-derived estimates for total 25(OH)D. A spiking experiment showed that the degree of cross-reactivity with 24,25(OH)2D was high and may underpin this positive bias. Adjustment for 24,25(OH)2D3 concentration brought estimates closer to true values. Data from the vitamin D RCT showed that the ratio of 24,25(OH)2D3 to 25(OH)D was associated with serum 25(OH)D3 and with response of serum 25(OH)D to vitamin D supplementation. CONCLUSIONS Our findings highlight that the effect of 24,25(OH)2D3 in serum is a double-edged sword—an interferent for some immunoassays, yet potentially informative of nutritional status.

Riboflavin Status

AbstractMeta-analyses of epidemiological data report that adults who carry a common polymorphism, the MTHFR 677C→T, in the gene encoding the folate-metabolising enzyme methylenetetrahydrofolate reductase (MTHFR) have a 40% increased risk of CVD and an 87% increased risk of hypertension. Riboflavin (vitamin B2), in its co-enzymatic form flavin adenine nucleotide (FAD), is required as a co-factor by MTHFR and previous trials in hypertensive patients have shown a blood pressure lowering response to riboflavin supplementation that is specific to individuals homozygous for this polymorphism (TT genotype). Low folate status is commonly reported in adults with the TT genotype however the effect of this genetic variant on riboflavin status has not previously been investigated. The aim of this study, therefore, was to investigate dietary intake and biomarker status of riboflavin by MTHFR genotype in Irish adults using data from the National Adult Nutrition Survey (2008–2010) (www.iuna.net).A 4-day semi-weighed food record was used to collect food and beverage intake data from a representative sample of 1500 Irish adults (18–90 years). Dietary intake data were analysed using WISP© based on UK food composition tables (modified to include recipes of composite dishes, nutritional supplements, fortified foods and generic Irish foods that were commonly consumed). Usual intakes were calculated via the NCI-method using SAS© Enterprise Guide. Blood samples (n = 1126) were collected by venepuncture by a trained professional and were processed and analysed using standard operating procedures. Biomarker status of riboflavin was determined by erthyrocyte gluthathione reductase activation coefficient (EGRac), a functional assay that measures the activity of the enzyme glutathione reductase before and after in vitro activation with its prosthetic group FAD; a lower value indicates better status.It was found that 12% of the population had the TT genotype. As expected, there was no significant difference in riboflavin intake across the genotype (CC, CT or TT) groups. Similarly, no significant genotype differences in riboflavin status (EGRac) were observed (1.36 vs 1.37 vs 1.38 respectively). Overall, 61% of the total population had EGRac values > 1.3, indicative of low/deficient status with no significant difference observed between the genotype groups (60%,61% and 61%, respectively).These data suggest that riboflavin status is not influenced by the C677T polymorphism in MTHFR in this cohort of nationally representative Irish adults. Further research is needed to see the impact of riboflavin status on blood pressure across the genotype groups in this nationally representative cohort of Irish adults.
