RESUMO

BACKGROUND: The aim of this study was to investigate the association of physical activity (PA) with assisted reproductive technology (ART) treatment and pregnancy outcomes among couples seeking infertility treatment. METHODS: This prospective cohort study was carried out among 128 infertile individuals (64 couples), entering the infertility clinic for ART procedures. Baseline PA (before entering any treatment) was assessed using accelerometry for both women and men. For every couple the infertility treatment outcomes were recorded. RESULTS: The couples that required invasive ART procedures such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) spent less time in vigorous PA (-73 min/week per couple, woman + man) than those couples who became spontaneously pregnant after entering the study (p = 0.001). We observed no significant associations between the time spent in physical activities and positive pregnancy test or live birth. CONCLUSIONS: Our results do not support a positive nor negative relation between the time the couples spent in physical activities and the chances of getting pregnant or having a baby among patients seeking infertility treatment. However, couples undergoing invasive ART procedures did less vigorous PA than couples that became spontaneously pregnant, suggesting that PA may interfere with their reproductive health.

RESUMO

INTRODUCTION: There is evidence demonstrating that certain lifestyle factors have a detrimental effect on fertility. Since such factors often coexist, possible synergistic effects merit further investigation. Thus we aimed to examine the cumulative impact of lifestyle factors on in vitro fertilization (IVF) early reproductive treatment outcomes and their interaction with measures of ovarian reserve. MATERIALS AND METHODS: By following women who were starting their first fresh IVF cycle in 2 cohorts, the "Lifestyle study cohort" (hypothesis generating cohort, n = 242) and the "UppSTART study" (validation cohort, n = 432) in Sweden, we identified two significant risk factors acting independently, smoking and BMI, and then further assessed their cumulative effects. RESULTS: Women with both these risk factors had an Incidence Rate Ratio (IRR) of 0.75 [(95% CI 0.61-0.94)] regarding the number of aspirated oocytes compared to women without these risk factors. Concerning the proportion of mature oocytes in relation to the total number of aspirated oocytes, the interaction between BMI and Antral Follicle Count (AFC) was significant (p-value 0.045): the lower the value of AFC, the more harmful the effect of BMI with the outcome. CONCLUSIONS: Data shows that there is an individual as well as a cumulative effect of smoking and BMI on the number of aspirated and mature oocytes in fresh IVF treatment cycles. AFC might modify associations between BMI and the proportion of mature oocytes in relation to the total number of aspirated oocytes. These results highlight the importance of lifestyle factors on IVF early reproductive outcomes and provide additional evidence for the importance of preconception guidance for the optimization of IVF cycle outcome.

RESUMO

AIM: The aim of this study was to investigate lifestyle habits and lifestyle adjustments among subfertile women trying to conceive. MATERIALS AND METHODS: Women (n = 747) were recruited consecutively at their first visit to fertility clinics in mid-Sweden. Participants completed a questionnaire. Data were analyzed using logistic regression, t tests, and chi-square tests. RESULTS: The response rate was 62% (n = 466). Mean duration of infertility was 1.9 years. During this time 13.2% used tobacco daily, 13.6% drank more than three cups of coffee per day, and 11.6% consumed more than two glasses of alcohol weekly. In this sample, 23.9% of the women were overweight (body mass index, BMI 25-29.9 kg/m(2)), and 12.5% were obese (BMI ≥30 kg/m(2)). Obese women exercised more and changed to healthy diets more frequently than normal-weight women (odds ratio 7.43; 95% confidence interval 3.7-14.9). Six out of ten women (n = 266) took folic acid when they started trying to conceive, but 11% stopped taking folic acid after some time. Taking folic acid was associated with a higher level of education (p < 0.001). CONCLUSIONS: Among subfertile women, one-third were overweight or obese, and some had other lifestyle factors with known adverse effects on fertility such as use of tobacco. Overweight and obese women adjusted their habits but did not reduce their body mass index. Women of fertile age would benefit from preconception counseling, and the treatment of infertility should routinely offer interventions for lifestyle changes.

RESUMO

INTRODUCTION: Prevalence of planned pregnancies varies between countries but is often measured in a dichotomous manner. The aim of this study was to investigate to what level pregnant women had planned their pregnancies and whether pregnancy planning was associated with background characteristics and pregnancy-planning behavior. MATERIAL AND METHODS: A cross-sectional study that utilized the baseline measurements from the Swedish Pregnancy Planning study. Pregnant women (n = 3390) recruited at antenatal clinics answered a questionnaire. Data were analyzed with multinomial logistic regression, Kruskal-Wallis H and chi-squared tests. RESULTS: Three of four pregnancies were very or fairly planned and 12% fairly or very unplanned. Of women with very unplanned pregnancies, 32% had considered an induced abortion. Women with planned pregnancies were more likely to have a higher level of education, higher household income, to be currently working (≥50%) and to have longer relationships than women with unplanned pregnancies. The level of pregnancy planning was associated with planning behavior, such as information-seeking and intake of folic acid, but without a reduction in alcohol consumption. One-third of all women took folic acid 1 month prior to conception, 17% used tobacco daily and 11% used alcohol weekly 3 months before conception. CONCLUSIONS: A majority rated their pregnancy as very or fairly planned, with socio-economic factors as explanatory variables. The level of pregnancy planning should be queried routinely to enable individualized counseling, especially for women with unplanned pregnancies. Preconception recommendations need to be established and communicated to the public to increase health promoting planning behavior.
