“…In the simulations, I did not mention variability in the variables; this issue may, however, be included in the class if the teacher thinks it would be of help. Somewhat similar issues can be found in the article by Gibson (2000), who shows that, in regression, situations similar to what is shown in figures 2 and 3 may happen even with random sampling from a population.…”

“…An in-person 24-hour dietary recall was assessed using the automated multiple-pass method in the mobile examination center by trained interviewers with the assistance of caretakers for children 11 years or younger . A single 24-hour recall allowed estimates of population means and differences between groups on a given day. Methods to classify SSBs (sodas, fruit drinks, sports and energy drinks, sweetened coffees and teas, and other) followed those of previous analyses .…”

cigarettes. It is possible that some pregnant women perceived e-cigarettes as a safe alternative to conventional cigarettes. In addition, some women who used conventional cigarettes might have switched to e-cigarettes in pregnancy as a means of smoking cessation. 6 A major limitation of this study is the limited sample size for pregnant women, although the overall sample size was large. As a result, the precision of the prevalence estimates among pregnant women may be limited. Further investigation with a larger sample size is warranted. Longitudinal studies starting from the preconception period are needed to determine the changing patterns in e-cigarette and conventional cigarette use among pregnant women.

“…A plasma folate concentration <6·8 nmol/l or an RBC folate concentration <317 nmol/l was used to indicate folate deficiency ( 12 ) . RBC folate ≥905 nmol/l was used to indicate optimal folate status for NTD prevention.…”

Objectives: To assess the folate and vitamin B 12 status of a group of Vietnamese women of reproductive age and to estimate the rate of neural tube defects (NTD) based on red blood cell (RBC) folate concentrations. Design and subjects: A representative sample of non-pregnant women (15-49 years) living in Hanoi City (n 244) and Hai Duong Province (n 245). Measures: RBC folate, plasma vitamin B 12 and plasma holo-transcobalamin (holoTC), a sensitive indicator of vitamin B 12 status. Results: Mean (95 % CI) concentrations of RBC folate, plasma B 12 and plasma holoTC were 856 (837, 876) nmol/l, 494 (475, 513) pmol/l and 78 (74, 82) pmol/l, respectively. Only 3 % and 4 % of women had plasma B 12 and holoTC concentrations indicative of deficiency. No woman had an RBC folate concentration indicative of deficiency (,317 nmol/l). Only 47 % of women had an RBC folate concentration $905 nmol/l. Accordingly, we predict the NTD rate in these regions of Vietnam to be 14?7 (14?2, 15?1) per 10 000 pregnancies. Conclusion: There was no evidence of folate and vitamin B 12 deficiency among this population of Vietnamese women. However, suboptimal folate status may be placing three out of five women at increased risk of NTD. Reductions in NTD rates are still possible and women would benefit from additional folic acid during the periconceptional period from either supplements or fortified foods.
