study author: Bajos, N, PhD
medscape reporter: Emma Hitt, PhD

June 17, 2010

new study in British Medical Journal, BMJ. 2010;340:c2573.
study based in France, survey in 2006

Nathalie Bajos, PhD, Institut National de la Santé et de la Recherche Médicale, in Kremlin Bicêtre, France
hypothesis: obese at greater risk of neg "sexual outcomes" dt soc stigma and lack of medical followup

men and women
5535 women and 4635 men randomly included
1010 women and 1488 men were overweight (body mass index [BMI], 25 to < 30 kg/m2)
411 women and 350 men were obese (BMI > 30 kg/m2).

FINDINGS
obese women less likely to report having any sex partners in last year (relative to normal wt women)
(odds ratio [OR], 0.71; 95% confidence interval [CI], 0.51 - 0.97)
obese men less likely (than norm wt men) to report having more than 1 sexual partner in a year
(OR, 0.31; 95% CI, 0.17 - 0.57; P < .001)
obese men were also more than twice as likely as normal-weight men to report having erectile dysfunction
(OR, 2.58; 95% CI, 1.09 - 6.11; P < .05).

in women higher BMI not related to sexual dysfunction (incl desire, arousal, dyspareunia)
obese women younger than 30 years less likely to use oral contraceptives
(OR, 0.34; 95% CI, 0.15 - 0.78)
or to seek healthcare services to attain contraceptives (OR, 0.37; 95% CI, 0.18 - 0.76)

obese women have 4x more unintended pregnancy
(OR, 4.26; 95% CI, 2.21 - 8.23).

marked sex effect:
partners of obese men and women were more tb obese
association stronger for women than for men

prevention of unintended preg = "major reproductive health challenge" --researchers

contraceptive data of study focus purely on oral contraception and condoms
long-acting reversible contraceptives not considered
"Dr. Goldbeck-Wood states that long-acting reversible contraceptives are suitable for obese women"
recommendations from the UK's National Institute for Health and Clinical Excellence
lower risk for venous thromboembolism and problems with weight-related dosage
require fewer visits to physician
Dr G-W says we need more research to know why obese woman have less sex, not using pills, getting more preg
mention of difficulty for docs to broach the subject

survey supported by the French National Agency of Aids Research and more

editorial: obese and lesbian = not pregnant
