Background: There is evidence that physical activity (PA), sitting time, and obesity may impact cognition, but few studies have examined this in young women. Methods: Healthy women (18–35 y), without conditions that impair cognition, were recruited for this cross-sectional study. Participants completed anthropometric and validated computerized cognitive assessments (IntegNeuro™). Performance on 5 cognitive domains (impulsivity, attention, information processing, memory, and executive function) was reported as z scores. Sitting hours and weekly PA calculated from time in low-, moderate-, and high-intensity activity were obtained via the International Physical Activity Questionnaire. Analysis of variance/analysis of covariance, chi-square, and linear regression were used. Results: 299 (25.9 [5.1] y) women (low PA = 19%; moderate PA = 40%; high PA = 41%) participated. High PA women had lower body mass index (high PA = 26.1 [6.5]; moderate PA = 30.0 [8.7]; low PA = 31.0 [11.1] kg/m2; P < .001) and less sitting time (high PA = 6.6 [3.1]; moderate PA = 7.7 [2.8]; low PA = 9.3 [3.6] hr/weekday; P < .0001). Cognitive function was within normal ranges and did not differ between any PA groups (P = .42). Adjusting for body mass index, C-reactive protein, or sitting hours did not alter results. Weak correlations were found between time in high-intensity activity and impulsivity (b = 0.12, r2 = .015; P = .04), and between sitting hours and information processing efficiency (b = −0.18, r2 = .03; P = .002). Valuesare presented as mean (SD). Conclusions: Cognitive function was within the normal range, regardless of PA or sitting time.

Abstract Background Anti-Müllerian hormone is a dimeric glycoprotein produced by the granulosa cells of preantral and small antral follicles of the ovaries. It is a reliable biomarker of ovarian reserve, ageing, and response in the management of women with infertility. However, there are few studies on the determinants of serum anti-Müllerian hormone in Nigerian women. This study aimed to investigate determinants of serum anti-Müllerian hormone among adult women of reproductive age. The study was a hospital-based cross-sectional study involving 161 women of reproductive age attending the gynaecology clinic and immunisation clinic of a Nigerian tertiary hospital. Baseline characteristics were collected using a semi-structured questionnaire. Serum anti-Müllerian hormone was quantified using enzyme-linked immunosorbent assay. Results In univariate analysis, age (B = − 0.035, P = 0.000), parity (B = − 0.080, P = 0.001), and infertility duration (B = − 0.050, P = 0.011) had a negative relationship with serum anti-Müllerian hormone, while ethnicity (B = 0.180, P = 0.040), body mass index (B = 0.015, P = 0.010), and cycle length (B = 0.042, P = 0.000) had a positive relationship with serum anti-Müllerian hormone. In multivariable analysis, all relationships except infertility duration persisted. Conclusion We found that age, ethnicity, parity, infertility duration, body mass index, and cycle length were associated with serum anti-Müllerian hormone. A large prospective population-based study is required to better understand factors that are associated with serum anti-Müllerian hormone in an ethnically diverse country like Nigeria.
