Many women undergoing fertility treatment make poor lifestyle choices that may affect treatment outcome
Abstract
STUDY QUESTION: What are the lifestyle choices and dietary aspects of women about to undergo fertility treatment in New Zealand? SUMMARY ANSWER: A considerable proportion of women about to undergo fertility treatment make poor lifestyle choices, including the consumption of alcohol and caffeine. WHAT IS KNOWN ALREADY: Women undergoing fertility treatment are highly motivated to achieve pregnancy, but there are relatively few published data on their lifestyle, lifestyle changes or dietary aspects. STUDY DESIGN, SIZE, DURATION: This was a cross-sectional study of 250 women aged 20-43 years, taking place between March 2010 and August 2011. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women about to undergo IVF or ICSI treatment in two large fertility clinics in Auckland and Hamilton, New Zealand. Lifestyle and dietary intake questionnaires were individually administered once to each participant 35 days (SD = 22) prior to fertility treatment initiation. Outcome measures included incidence of smoking, consumption of alcohol and caffeinated beverages, BMI, detailed intake of dietary supplements and fertility treatment success. Consumption of certain nutrient supplements was compared with the general female New Zealand population. MAIN RESULTS AND THE ROLE OF CHANCE: There were high rates of alcohol (50.8%) and caffeine (86.8%) consumption. Most women (82.8%) reported at least one lifestyle change in preparation for fertility treatment, but less than half of women who consumed alcohol regularly reduced their intake and 60% did not change consumption of caffeinated beverages. Similarly, the majority of women did not change their exercise levels (64.4%) or BMI (83.6%) ahead of fertility treatment. Coffee intake appeared unrelated to treatment outcome, but women who consumed caffeinated herbal tea (36.4% of the study population consumed green tea) had lower odds of becoming pregnant (odds ratio, OR 0.52; P = 0.041 versus those not consuming caffeinated herbal tea). Women who abstained from drinking or reduced alcohol intake had twice the odds of becoming pregnant than those who maintained their drinking habits prior to fertility treatment (OR 2.27; P = 0.049). While 93.2% of women took a folic acid supplement, 16.8% had an inadequate intake compared with the current New Zealand prenatal recommendation of 800 mcg/day. Women who held a university degree or higher qualification had twice the odds of becoming pregnant as women with lower levels of education (OR 2.08; P = 0.017), though this finding appeared to be unrelated to lifestyle or dietary habits. LIMITATIONS, REASONS FOR CAUTION: The study involved self-reported behaviours that might have been misrepresented by respondents. In addition, our questionnaires covered the period following the first clinical assessment but ∼5 weeks prior to fertility treatment initiation, so that we cannot ascertain whether dietary intakes and lifestyle choices persisted over the course of treatment itself. WIDER IMPLICATIONS OF THE FINDINGS: Many women about to undergo fertility treatment make poor lifestyle choices that may negatively affect their chances of becoming pregnant. These findings may be more widely applicable to other women attempting to become pregnant. Specific advice for women regarding healthy lifestyle choices while undergoing fertility treatment is warranted. STUDY FUNDING/COMPETING INTERESTS: A.A.G. received financial support from Abbott Nutrition Research & Development Asia-Pacific Center; J.C.P. is a shareholder of Fertility Associates; the other authors have no financial or non-financial conflicts of interest to disclose.

Fertility clinics have seen increasing numbers of patients with unhealthy lifestyles and have increasingly recognised the importance of preconception lifestyle advice.
“Over past years, fertility clinics have tended to see an increasing number of patients with an unhealthy lifestyle, and they have acknowledged more and more the importance of providing preconception lifestyle advice (Gormack 2015, Homan 2018).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
