[Resident and supervisor perception of learning climate in public health resident training in the Netherlands]. / Leerklimaat perceptie van aios en supervisors binnen de vernieuwde medische vervolgopleiding arts Maatschappij + Gezondheid.

Introduction: The purpose of this study was to evaluate the perceived quality of the learning climate by public health residents in the Netherlands and compare residents' and supervisors' perceptions. Methods: Residents of five public health subfields, who started their residency programs in 2019 and onwards, as well as supervisors involved in the residency program, were invited to complete a web-based survey based on an adapted version of the D­RECT questionnaire. Answers of residents and supervisors of the same training site and public health subfield were matched to compare perceived quality of the learning climate. Results: One hundred fourteen residents responded (response rate 50.9%). Residents' overall assessment of the learning climate showed a mean score of 4.19 on a 5-point-scale. Thirty-eighth supervisor-resident matches were formed. There were no notable differences in the perception of residents and supervisors. Conclusion: Residents' overall assessment of the learning climate was positive. Supervisors and residents' perception of learning climate is equal. Our adapted version of D­RECT seems to be suitable to evaluate the learning climate for public health residency programs in the Netherlands. Further research is necessary to validate our questionnaire and to confirm our findings.

Developmental origins of polycystic ovary syndrome (PCOS), a case control study comparing birth weight in women with PCOS and control group.

Evidence from various epidemiological studies and experimental animal studies has linked adverse intrauterine circumstances with health problems in adult life. This field of investigation is known as Developmental Origins of Health and Disease (DOHaD). Studies investigating the relation between developing polycystic ovary syndrome (PCOS) in adulthood and birth weight have yielded inconsistent results: PCOS is described more often in women with low birth weight and high birth weight, while other studies have failed to establish any relation. In this retrospective case-control study, we evaluated whether women diagnosed with PCOS had lower birth weight compared to women with a regular menstrual cycle (controls). Binary logistic regression models were used to analyze the data and correct for known confounders. About 65 women with PCOS and 96 controls were recruited for this purpose. The average birth weight of PCOS women (3357 g) did not differ from the average birth weight of controls (3409 g). Mean age at menarche differed significantly between groups, 13.7 years and 12.8 years (p = 0.006), respectively, for PCOS women and controls. In conclusion, we could not confirm the effect of adverse intrauterine conditions, reflected in birth weight, on developing PCOS.
