Project description:This study used a sequential two-phase explanatory design. The first phase of this mixed-methods design aimed to explore conflict resolution strategies in adolescent dating couples, and the second phase to document, from both the perspective of the individual and of the couple, dyadic interaction patterns distinguishing youth inflicting dating violence from those who do not. A sample of 39 heterosexual couples (mean age 17.8 years) participated in semi-structured interviews and were observed during a 45 min dyadic interaction. At phase 1, qualitative analysis revealed three main types of conflict resolution strategies: 1) negotiating expectations and individual needs; 2) avoiding conflicts or their resolution; 3) imposing personal needs and rules through the use of violence. At phase 2, we focused on couples with conflictive patterns. Results indicate that couples who inflict violence differ from nonviolent couples by their tendency to experience conflicts when in disagreement and to resort to negative affects as a resolution strategy. In addition, while at an individual level, they show a tendency to withdraw from conflict and to use less positive affect, at a dyadic level they present less symmetry. Results offer important insights for prevention programs.

Project description:Indigenous and other marginalized racial/ethnic minorities have poorer health status than majority populations, including higher rates of type 2 diabetes. These disparities have typically been addressed using a 'deficit-based' discourse that isolates disease management from the broader social, economic, political context and does not incorporate patient perspectives. We aimed to explore factors affecting glycemic control among Indigenous Arabs with diabetes in Israel using a strengths-based approach that centered participants' knowledge of their context, needs, resources and strengths. We conducted an exploratory sequential mixed methods study, which included 10 focus groups (5 men's, 5 women's) and 296 quantitative in-person surveys. Participants with diagnosed diabetes were randomly drawn from the patient list of the largest healthcare service organization (survey response rate: 93%). Prominent and interconnected themes emerged from focus group discussions, including: diet, physical activity, and social, economic, mental/psychological and political stress. The discussions raised the need for adapting diabetes management approaches to incorporate participants' communal, physical and psychological well-being, and socioeconomic/political realities. The connections between these factors and diabetes management were also reflected in multivariable analyses of the survey data. Women (OR: 2.03; 95% CI: 1.09-4.63), people with disabilities (OR: 2.43; 95% CI: 1.28-4.64), and unemployed people (OR: 2.64; 95% CI: 1.28-5.44) had higher odds of economic barriers to diabetes management. Furthermore, female sex (OR: 2.26; 95% CI: 1.25-4.09), unemployment (OR: 4.07; 95% CI: 1.64-10.10), and suboptimal glycemic control (OR: 1.20, 95% CI: 1.03-1.41 per 1-unit increase in HbA1c) were associated with moderate-to-severe depressive symptoms. A pro-active, team-based healthcare approach incorporating Indigenous/minority participants' knowledge, experience, and strengths has the potential to improve individuals' diabetes management. Healthcare services should be structured in ways that enable providers to listen to their patients, address their key concerns, and foster their strengths.

Project description:ObjectiveTo determine patient experience and perception following a diagnosis of non-muscle-invasive bladder cancer (NMIBC).Patient and methodsPatients were part of a prospective multicentre observational study recruiting patients with NMIBC for a urine biomarker study (DETECT II; ClinicalTrials.gov: NCT02781428). A mixed-methods approach comprising: (i) the Brief Illness Perception Questionnaire (Brief-IPQ) and (ii) semi-structured interviews to explore patients' experience of having haematuria, and initial and subsequent experience with a NMIBC diagnosis. Both assessments were completed at 6 months after NMIBC diagnosis.ResultsA total of 213 patients completed the Brief-IPQ. Patients felt that they had minimal symptoms (median [interquartile range, IQR] score 2 [0-5]) and were not particularly affected emotionally (median [IQR] score 3 [1-6]) with a minimal effect to their daily life (median [IQR] score 2 [0-5]). However, they remained concerned about their cancer diagnosis (median [IQR] score 5 [3-8]) and felt that they had no personal control over the cancer (median [IQR] score 2 [2-5]) and believed that their illness would affect them for some time (median [IQR] score 6 [3-10]). A significant association with a lower personal control of the disease (P < 0.05) and a poorer understanding of the management of NMIBC (P < 0.05) was seen in patients aged >70 years. Many patients were uncertain about the cause of bladder cancer. Qualitative analysis found that at initial presentation of haematuria, most patients were not aware of the risk of bladder cancer. Patients were most anxious and psychologically affected between the interval of cystoscopy diagnosis and transurethral resection of bladder tumour (TURBT). Following TURBT, most patients were positive about their cancer prognosis.ConclusionPatients with NMIBC have a poor perception of disease control and believe that their disease will continue over a prolonged period of time. This is particularly more pertinent in the elderly. Patients are most psychologically affected during the interval between cancer diagnosis following cystoscopy and TURBT. Health awareness about bladder cancer remained poor with a significant number of patients unaware of the causes of bladder cancer. Psychological support and prompt TURBT following bladder cancer diagnosis would help improve the mental health of patients with NMIBC.

Project description:Objective: Contemporary healthcare requires physicians to have well developed ethical judgment skills in addition to excellent clinical skills. However, no consensus has been reached on how to best teach ethical judgment skills during medical training. Previous studies revealed inconclusive results and applied varying theoretical frameworks. To date, the students' perspectives on their development in ethical judgment has received less attention. Better insights in the learners' experiences can help to improve educational interventions in medical ethics. Methods: A vignette featuring a challenging case with opposing views between a patient's parents and a physician followed by a questionnaire was presented to a cohort of medical students at a German medical school at three points in time during their medical training (Year 1, 2 and 5). The questionnaire included closed and open-ended questions addressing the participant's preferred, hypothetical actions, their reasoning as well as the resources informing their reasoning. Content analysis was used for qualitative data; frequencies and percentages were used to describe quantitative findings. Results: The response rate remained stable (28%) over the study period. Participants' responses changed overtime. Accepting parents' autonomy in the decision-making process was the majority standpoint of students in year 1 and 2 and became less often cited in year 5 (Year 1/2/5: 68/67/48%). On the contrary, not readily following the parents' decision for medical reasons was a minority standpoint in year 1 and became more prevalent over time (year 1/2/5: 12/17/42%). Judgments were only partly based on ethics training. Instead, participants drew on experiences from their clinical clerkships and their personal lives. Throughout the study, participants did not feel well-prepared to make a judgment in the case (Average 2.7 on a Likert-Scale; 1=very well prepared, 4=very poor). Conclusions: Over the course of their medical training, the participants seemed to increasingly frame the presented vignette as a medical problem. To optimize the development of ethical judgment teaching of ethics should be more integrated in clinical teaching. In addition to the analysis of rare and extreme cases, teaching ethics should also expand on challenges students and junior doctors commonly encounter themselves to promote ethical sensitivity and confidence in students.

Project description:Mistimed sleep/wake and eating patterns put shift workers at increased risk for cardiometabolic disease, and epigenetic modification of circadian genes has been proposed as a mechanism. Although not as extreme as shift workers, adolescents often have delayed sleep timing and irregular eating patterns. The aim was to assess whether sleep midpoints - median of bed and wake time - and dietary patterns in adolescents were associated with DNA methylation of circadian genes. The study population included 142 Mexican youth (average age of 14.0 (SD = 2.0) years, 49% male). Average sleep midpoint over weekdays was estimated with actigraphy. Diet was assessed with a semi-quantitative food frequency questionnaire, and three dietary patterns were derived from principal component analysis, a Plant-based & lean proteins pattern, a Meat & starchy pattern, and an Eggs, milk & refined grain pattern. DNA methylation was quantified in blood leukocytes with the Infinium MethylationEPIC BeadChip, and data from 548 CpG sites within 12 circadian genes were examined. Linear regression analyses, adjusted for sex, age, and % monocytes, showed that later sleep timing was associated with higher DNA methylation of several circadian genes, notably with RORB, PER1, CRY2, and NR1D1. Each of the dietary patterns examined was also related to circadian gene DNA methylation, but the Eggs, milk & refined grain pattern ('breakfast' pattern) had the clearest evidence of relationships with circadian genes, with inverse associations (lower DNA methylation) across all 12 genes. Findings suggest that timing-related sleep and eating behaviours among adolescents could result in epigenetic modification of clock genes.

Project description:OBJECTIVE:Childhood obesity has increased rapidly in Mexico, along with changes in the food environment. However, little is known about the dietary patterns (DP) of Mexican children. We aimed to characterize the DP of schoolchildren and to analyse their associations with sociodemographic factors. DESIGN:Cross-sectional analysis. Dietary and sociodemographic information was obtained, including a single 24 h recall, socio-economic status (SES), geographic region, area of residence and ethnicity. DP were defined with cluster analysis (using k-means). Multinomial logistic regression models, adjusted for the survey design, were used to assess associations between DP and sociodemographic variables. SETTING:2012 Mexican National Health and Nutrition Survey (ENSANUT-2012). SUBJECTS:Schoolchildren (n 2751) aged 5-11 years who participated in ENSANUT-2012. RESULTS:Four DP were identified: 'Traditional', 'Industrialized', 'Varied' and 'Modern'. Reported energy intake (mean (sd)) was lowest in the 'Traditional' and highest in the 'Industrialized' DP (7037 (3707) kJ/d (1682 (886) kcal/d) v. 8427 (3753) kJ/d (2014 (897) kcal/d), respectively, P<0·05). Significant differences in fat and fibre intakes were seen across DP. Non-indigenous v. indigenous children were 22·0 times (95 % CI 5·1, 93·6) more likely to have a 'Modern' rather than 'Traditional' DP. Relative likelihood of having an 'Industrialized' rather than 'Traditional' DP was 6·2 (95 % CI 3·9, 9·9) among schoolchildren from high SES v. low SES. CONCLUSIONS:Among Mexican schoolchildren, DP were associated with sociodemographic variables. Non-indigenous children were significantly more likely to consume a 'Modern' than a 'Traditional' DP. Children with higher SES were more likely to have an 'Industrialized' pattern. It is necessary to consider dietary characteristics in the different sociodemographic strata when dietary interventions are designed.

Project description:Mammary tissue experiences the highest rate of proliferation during adolescence representing a period of heightened susceptibility. Few prospective studies have examined adolescent diet and breast cancer, and none have examined dietary patterns. Thus, we examined the association between adolescent dietary patterns and a diet quality index, the Alternative Healthy Eating Index (AHEI), and breast cancer in the Nurses' Health Study II among those who completed a 124-item food frequency questionnaire about their high-school diet (HS-FFQ). Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (95% CI). Among 45204 women who completed the HS-FFQ, 863 cases of premenopausal breast cancer and 614 cases of postmenopausal cancer were diagnosed. A marginal inverse association was observed between the 'prudent' dietary pattern, characterized by high intake of vegetables, fruits, legumes, fish and poultry, and premenopausal breast cancer. Women in fifth quintile had a multivariable adjusted HR (95% CI) of 0.84 (0.67-1.04) for premenopausal breast cancer (Ptrend= 0.07) compared with the first quintile. Scoring higher on the AHEI was borderline significantly associated with premenopausal breast cancer with a HR of 0.81 (0.64-1.01) for the fifth quintile (Ptrend= 0.08), and this association appeared to be stronger for estrogen receptor-negative/progesterone receptor-negative tumors. No association was observed between the 'Western' pattern or the 'fast-food' pattern. Results were similar for each of these patterns when both premenopausal and postmenopausal breast cancer were considered together. An overall healthy diet during adolescence, similar to the prudent dietary pattern or adherence to the AHEI, may contribute to reducing the risk of breast cancer.

Project description:Optimizing protein intake is a novel strategy to prevent age associated loss of muscle mass and strength in older adults. Such a strategy is still missing for older adults from ethnic minority populations. Protein intake in these populations is expected to be different in comparison to the majority of the population due to several socio-cultural factors. Therefore, the present study examined the dietary protein intake and underlying behavioral and environmental factors affecting protein intake among older adults from ethnic minorities in the Netherlands. We analyzed frequency questionnaire (FFQ) data from the Healthy Life in an Urban Setting (HELIUS) cohort using ANCOVA to describe dietary protein intake in older adults from ethnic minorities in the Netherlands (N = 1415, aged >55 years, African Surinamese, South Asian Surinamese, Moroccan, and Turkish). Additionally, we performed focus groups among older adults from the same ethnic minority populations (N = 69) to discover behavioral and environmental factors affecting protein intake; 40-60% of the subjects did not reach minimal dietary protein recommendations needed to maintain muscle mass (1.0 g/kg bodyweight per day (BW/day)), except for Turkish men (where it was 91%). The major sources of protein originated from animal products and were ethnic specific. Participants in the focus groups showed little knowledge and awareness about protein and its role in aging. The amount of dietary protein and irregular eating patterns seemed to be the major concern in these populations. Optimizing protein intake in these groups requires a culturally sensitive approach, which accounts for specific protein product types and sociocultural factors.

Project description:BackgroundEvidence suggests that inadequate hospital practices, as well as sociocultural and community factors have detrimental effects on timely initiation as the first breastfeed within first hour after birth, and exclusive breastfeeding. The purpose of the study was to examine the factors that influence timely initiation of breastfeeding and exclusive breastfeeding at birth and 1 month postpartum in Mexican women delivering in public and private hospitals.MethodsMixed methods were conducted between May and July 2017, including surveys (n = 543) and semi-structured interviews (n = 60) in the immediate (7 h) and intermediate (30 days) postpartum periods. Participants were women aged 15-49 years, in public and private hospitals, of urban and rural municipalities of Chihuahua and Puebla, Mexico.ResultsTimely initiation was reported by 49.4% of mothers, and 34.7% reported that their children received infant formula at the hospital. Only 44.8% of women reported exclusive breastfeeding at 1 month postpartum. Timely initiation of breastfeeding was higher in women with vaginal delivery (62.1 vs 35.5%; p < 0.05) and those who received information during pregnancy (OR 1.07; p = 0.018). Exclusive breastfeeding at 1 month postpartum was related to older maternal age (OR 1.05; p < 0.001) and the fact that the mothers had received more information about breastfeeding during pregnancy (OR 1.13; p = 0.0001). Infant formula use was less associated with timely initiation (OR 0.46; p = 0.001). Participants in qualitative data identified the emotional, physical and economic benefits of breastfeeding, however, the perception about insufficient production of human milk, and the belief that infant formula is recommended, persists.ConclusionsModification of hospital practices, such as decreasing the number of cesarean and the use of infant formula, as well as the support of the initiation and continuation of exclusive breastfeeding by health personnel and family members, could help increase breastfeeding practices in Mexican women.

Project description:BACKGROUND:Sociodemographic characteristics are associated with the dietary patterns of populations. However, the direction of the association is not consistent among countries: it is contingent on the nutritional transition phase, level of economic development, cultural contexts and both the social and health policies prevailing in each country. The objective of this study was to identify the trends in dietary patterns observed in 2006, 2012 and 2016 among Mexican adults by sociodemographic characteristic. METHODS:To determine and compare dietary patterns, we performed a secondary analysis of dietary and sociodemographic data for adults 20-59?years old. Data were drawn from the 2006 and 2012 National Health and Nutrition Surveys (ENSANUTs) together with the 2016 Half-Way National Health and Nutrition Survey (ENSANUTMC). To estimate the dietary patterns, we used an adapted version of the Healthy Eating Index-2015 (HEI-2015) and a quantile-based regression model to compare the HEI medians by sociodemographic characteristic. RESULTS:From 2006 to 2016, the quality of the diet of Mexican adults scored under 50 points on a scale of 0 to 100, markedly below the maximum scores for the majority of HEI-2015 components. Diet quality varied according to age, sex, socioeconomic status (SES), area (urban/rural) and region of residence, with the highest quality observed among older individuals (within the 40-59 age group), women, people of lower SES and residents of rural areas, particularly in southern Mexico. Although this trend remained constant overall throughout 2006, 2012 and 2016, specific HEI-2015 components showed an opposite trend by sociodemographic strata. CONCLUSION:The diet quality of Mexican adults was suboptimal from 2006 to 2016, with notorious disparities persisting over time among sociodemographic strata. Our results can serve as a basis for formulating recommendations on ways to improve the population diet, where those components diverging the most from adequate scores could be highlighted in public-health messages.
