Prevalence of Musculoskeletal Pain and Statin Use
BACKGROUND: Muscle effects are the most common reported adverse effects of 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins). However, in placebocontrolled trials the incidence of muscle pain is most often similar for placebo and active control groups.
OBJECTIVE: We sought to evaluate whether statin use was associated with a higher prevalence of musculoskeletal pain in a nationally representative sample.
METHODS: Cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 1999–2002. Participants were 3,580 adults ≥40 years without arthritis who were interviewed at home and examined in a mobile examination center. Participants were asked about sociodemographic characteristics, health conditions, medication use, and musculoskeletal pain. Height, weight, blood pressure, ankle brachial index, and cholesterol were measured.
MEASUREMENTS AND MAIN RESULTS: Prevalence and adjusted odds ratios (OR) of any musculoskeletal pain and musculoskeletal pain in 4 different anatomical regions (neck/upper back, upper extremities, lower back, and lower extremities) by statin use during the last 30 days. Among statin users (n=402), 22.0% (95% CI 18.0–26.7%) reported musculoskeletal pain in at least 1 anatomical region during the last 30 days, compared with 16.7% (95%CI 15.1–18.4%) of those who did not use a statin. Compared to persons who did not use statins, those who used statins had multivariable-adjusted odds ratios (95%CI; p value) of 1.50 (1.07–2.11; p=.01) for any musculoskeletal pain, 1.59 (1.04–2.44, p=.03) for lower back pain, and 1.50 (1.02–2.22, p=.03) for lower extremity pain.
CONCLUSION: Musculoskeletal pain is common in adults ≥40 years without arthritis. In this nationally representative sample, statin users were significantly more likely to report musculoskeletal pain
Endocrine regulation of human fetal growth: The role of the mother placenta and fetus
© 2006 by The Endocrine SocietyThe environment in which the fetus develops is critical for its survival and long-term health. The regulation of normal human fetal growth involves many multidirectional interactions between the mother, placenta, and fetus. The mother supplies nutrients and oxygen to the fetus via the placenta. The fetus influences the provision of maternal nutrients via the placental production of hormones that regulate maternal metabolism. The placenta is the site of exchange between mother and fetus and regulates fetal growth via the production and metabolism of growth-regulating hormones such as IGFs and glucocorticoids. Adequate trophoblast invasion in early pregnancy and increased uteroplacental blood flow ensure sufficient growth of the uterus, placenta, and fetus. The placenta may respond to fetal endocrine signals to increase transport of maternal nutrients by growth of the placenta, by activation of transport systems, and by production of placental hormones to influence maternal physiology and even behavior. There are consequences of poor fetal growth both in the short term and long term, in the form of increased mortality and morbidity. Endocrine regulation of fetal growth involves interactions between the mother, placenta, and fetus, and these effects may program long-term physiology.Vanessa E. Murphy, Roger Smith, Warwick B.
