Dietary patterns and their socioeconomic factors of adherence among adults in urban Burkina Faso: a cross-sectional study

BACKGROUND

Sub-Saharan African populations undergo a nutrition transition towards diets associated with increased risk for metabolic and cardiovascular diseases. For targeted prevention, we aimed to characterize dietary patterns and determine their sociodemographic factors of adherence.

METHODS

We recruited 1,018 adults aged >  = 25 years from two formal and three informal settlements within the Health and Demographic Surveillance System, Ouagadougou, Burkina Faso, between February and April 2021. In a cross-sectional sample, a culture-specific food-propensity questionnaire with 134 food items and a sociodemographic questionnaire were used to collect the data. Exploratory dietary patterns were derived using principal component analysis, and sociodemographic factors of adherence were calculated using multivariable linear regression models.

RESULTS

In this study population (median age: 42 years, interquartile range 21 years; male: 35.7%), the diet relied on starchy foods and other plant-based staples with rare consumption of animal-based products. We identified three dietary patterns, explaining 10.2%, 9.8%, and 8.9% of variation in food intake, respectively: a meat and egg-based pattern associated with younger age, male sex, better education, and economic situation; a fish-based pattern prevailed among women, higher educational levels, and better economic situation; and a starchy food-based was associated with younger age and sharing a home with other adults.

CONCLUSIONS

This study population is at an early stage of the nutrition transition and shows low intakes of health-beneficial food groups. Yet, progress along the nutrition transition varies according to age, educational attainment, and economic status. Particularly, younger and well-off people seem to adhere more strongly to diets high in animal-based products. These findings can inform strategies in public health nutrition for sub-Saharan African populations.

Sustainable dietary weight loss intervention and its effects on cardiometabolic parameters and greenhouse gas emissions: study protocol of a randomised controlled trial with overweight and obese adults in Ouagadougou, Burkina Faso

INTRODUCTION

The global obesity epidemic and its adverse health effects have reached sub-Saharan Africa. In some urban settings, like Burkina Faso's capital Ouagadougou, up to 43% of the adult population are overweight or obese. At the same time, modernised food systems are responsible for 26% of global greenhouse gas emissions, 50% of land use and 70% of freshwater use. International guidelines on the treatment of overweight and obesity recommend dietary intervention programmes that promote reduced calorie intake and increased physical activity. So far, weight loss interventions rarely consider sustainable dietary concepts, including healthfulness, affordability, cultural appropriateness and environmental friendliness. Therefore, we present a study protocol of a novel randomised controlled trial that aims to establish the effects of a sustainable weight loss intervention on cardiometabolic and environmental outcomes in urban Burkina Faso.

METHODS AND ANALYSIS

We conduct a non-blinded randomised controlled trial, comparing a 6-month sustainable diet weight loss intervention programme (n=125) with a standard weight loss information material and 5 min oral counselling at baseline (n=125). Primary outcome is a reduction in fasting plasma glucose of ≥0.1 mmol/L. Outcome measures are assessed at baseline, after 6 months and after 12 months.

ETHICS AND DISSEMINATION

Ethical approval for the study has been obtained from the Medical Faculty of Heidelberg University (S-376/2019) and from the Ministry of Health and the Ministry of Higher Education, Scientific Research and Innovation in Ouagadougou, Burkina Faso (No 2021-01-001). The results of the study will be disseminated to local stakeholders at a final project meeting and to the wider research community through peer-reviewed publications and conferences.

[Special care units for the treatment of acutely ill, cognitively impaired geriatric patients in Germany]

During recent years, specialized wards have been established in geriatric hospital departments as a consequence of the growing need of special care for acutely ill older patients, who are also cognitively impaired. However, there are neither established standards nor any commonly agreed concept of care. A written survey among 12 specialized wards in Germany revealed some characteristics of these wards: extended geriatric assessment, special education of staff including validation and gerontopsychiatric issues, and particular equipment/architecture, such as hidden doors and group rooms, and in some cases loop tracks for walking, therapeutic facilities, and 'living rooms' on the wards. There is a wide variability with respect to the designation of these wards, the number of beds, length of stay, and admission criteria. It appears from this survey that there should be an exchange of empirical experience made on these wards, and there is a need of collaborative research on its usefulness.

Paracetamol for pain relief after surgical removal of lower wisdom teeth

BACKGROUND

Paracetamol has been commonly used for the relief of postoperative pain following oral surgery. In this review we investigated the optimal dose of paracetamol and the optimal time for drug administration to provide pain relief, taking into account the side effects of different doses of the drug. This will inform dentists and their patients of the best strategy for pain relief after the surgical removal of wisdom teeth.

OBJECTIVES

To assess the beneficial and harmful effects of paracetamol for pain relief after surgical removal of lower wisdom teeth, compared to placebo, at different doses and administered postoperatively.

SEARCH STRATEGY

We searched the Cochrane Oral Health Group's Trials Register; the Cochrane Pain, Palliative and Supportive Care Group's Trials Register; CENTRAL; MEDLINE; EMBASE and the Current Controlled Trials Register. Handsearching included several dental journals. We checked the bibliographies of relevant clinical trials and review articles for studies outside the handsearched journals. We wrote to authors of the identified randomised controlled trials (RCTs), to manufacturers of analgesic pharmaceuticals, we searched personal references in an attempt to identify unpublished or ongoing RCTs. No language restriction was applied. The last electronic search was conducted on 24th August 2006.

SELECTION CRITERIA

Randomised, parallel group, placebo controlled, double blind clinical trials of paracetamol for acute pain, following third molar surgery.

DATA COLLECTION AND ANALYSIS

All trials identified were scanned independently and in duplicate by two review authors, any disagreements were resolved by discussion, or if necessary a third review author was consulted. The proportion of patients with at least 50% pain relief was calculated for both paracetamol and placebo. The number of patients experiencing adverse events, and/or the total number of adverse events reported were analysed.

MAIN RESULTS

Twenty-one trials met the inclusion criteria. A total of 2048 patients were initially enrolled in the trials (1148 received paracetamol, and 892 the placebo) and of these 1968 (96%) were included in the meta-analysis (1133 received paracetamol, and 835 the placebo). Paracetamol provided a statistically significant benefit when compared with placebo for pain relief and pain intensity at both 4 and 6 hours. Most studies were found to have moderate risk of bias, with poorly reported allocation concealment being the main problem. Risk ratio values for pain relief at 4 hours 2.85 (95% confidence interval (CI) 1.89 to 4.29), and at 6 hours 3.32 (95% CI 1.88 to 5.87). A statistically significant benefit was also found between up to 1000 mg and 1000 mg doses, the higher the dose giving greater benefit for each measure at both time points. There was no statistically significant difference between the number of patients who reported adverse events, overall this being 19% in the paracetamol group and 16% in the placebo group.

AUTHORS' CONCLUSIONS

Paracetamol is a safe, effective drug for the treatment of postoperative pain following the surgical removal of lower wisdom teeth.

[Improving the quality of clinical interview teaching: evaluation of an intervention with medical students]

BACKGROUND

Quality of clinical interview is a key issue both for patient satisfaction and for diagnostic efficiency. Its adequacy relates to better clinical diagnosis treatment plans and patient compliance.

AIM

To measure the quality of interviews performed by medical students in three Chilean medical schools before receiving specific training on the subject and to compare the scores obtained after introductory courses on interview.

MATERIAL AND METHODS

The interviews were videotaped and then evaluated using an objective scale, that measures 33 skills grouped in six areas: opening, problem exploration, non verbal facilitation, interpersonal patient reaction and closing. The students were assigned to an experimental group that received an interactive workshop with role-plays, vignettes and videotape feedback, and to a non intervention group that received the usual bedside training on medical interviews.

RESULTS

Both groups shared the same skill level before the training, with better scores on nonverbal, patient reaction and problem exploration, and worse ones on closing and interpersonal skills. Comparing pre and post-test results, the overall score improved in the experimental group (from 33.2 to 38.3, p = 0.002) and worsened among non intervened students. There were statistically significant changes for opening (p < 0.002), problem exploration (p < 0.05), non verbal facilitation (p < 0.0001) and closing (p < 0.0001).

CONCLUSIONS

It is important to train students not only in specific knowledge contents but in the process of interview. This training should encourage the development of empathy and closing skills.

[Communications difficulties during the medical interview]

The aims of medical interview are to obtain diagnostic information, to obtain an empathetic communication with the patient, to educate him about his disease and to establish a personal link allowing a lasting relationship. We analyze some features of communication with patients. Individualized communication, recognizing his identity and personal aspects, "looking from the patient". Context, a shared but not mentioned value, part of the world of emotions and ideas. An analog and digital language, the former precise in words and the latter more diffuse, with gestures, not verbal. Coherence, as the similitude between what we think, feel and say. If there is no coherence, communication is impaired. Emotions, always present, rending communication more valid and real. We need to recognize, express and respond to emotions. An emotionless patient becomes a distant and impersonal object, an "it". When emotions are incorporated the patient is a "him" with whom I share and dialog. Empathy is an emotional comprehension, a personal bond. It improves relationships and creates links. Compassion is a variation of empathy that includes spiritual aspects and values. Negative emotions as rage, frustration and aggression creates communicational difficulties. We must recognize, express and clarify them to improve the situation. Difficult patients with whom communication is difficult such as confuse, agitated, terminal, elder, manipulating or hypochondriac subjects. The idea of transference and counter transference in these complicated situations is analyzed.

Problems in the control of hypertension in the community

A hypertension survey was conducted in Montreal to determine the extent, nature and distribution of the control of hypertension. Of the 12 055 persons screened in shopping centres, workplaces and a random sample of homes in four census tracts the hypertension was not controlled in 69.0% to 80.3% of those with the condition in each setting. Nearly two thirds of those with hypertension were aware of their condition, 13% were aware but had never been treated, 13% were receiving treatment inadequate to control their hypertension, and 11% had discontinued treatment, most reporting that they had done so on the advice of their physician. Among those screened in their home, discontinuance of therapy was most often reported by those with a low income, but lack of awareness of their condition was no more prevalent in this group than in the other income groups. Efforts to control hypertension should be directed to the variety of causes of lack of control, which may occur with various frequencies in different communities, and for which screening alone may be inadequate.
