      &lt;p&gt;After a decade of decline, the rate of teenage pregnancies increased by 3% in 2006 as 750,000 women younger than 20 became pregnant, according to a report released by the Guttmacher Institute.&lt;/p&gt;
&lt;p&gt;And as pregnancies increased, so did births  --  41.9 births per 1,000 U.S. teenage girls, which was 4% higher than in 2005  --  and abortions, which increased by 1% from 2005 to 2006.&lt;/p&gt;
&lt;p&gt;In a prepared statement, Planned Parenthood blamed abstinence-only sex education programs for the uptick.&lt;/p&gt;
&lt;p&gt;&quot;It is a tragedy that after a decade of progress in reducing the rate of teenage pregnancy we are witnessing a substantial increase in the number of teens who are getting pregnant,&quot; Planned Parenthood said.&lt;/p&gt;
&lt;p&gt;In a statement released last May in conjunction with the &quot;National Day to Prevent Teen Pregnancy&quot; the American College of Obstetricians and Gynecologists (ACOG), agreed that comprehensive sex education was likely to be more effective than abstinence-only programs.&lt;/p&gt;
&lt;p&gt;&quot;Abstinence works for some teens, but the idea that most teens will wait to have sex indefinitely is rigid and impractical,&quot; said Richard S. Guido, MD, chair of the ACOG&apos;s Committee on Adolescent Health Care.&lt;/p&gt;
&lt;p&gt;But the Guttmacher report suggested that the reasons for increase may be more complex, including &quot;shifts in the racial and ethnic composition of the population, increases in poverty, the growth of abstinence-only sex education programs at the expense of comprehensive programs, and changes in public perception and attitudes toward both teenage and unintended pregnancy.&quot;&lt;/p&gt;
&lt;p&gt;Among black teenagers the pregnancy rate was 126.3 per 1,000 versus 44 per 1,000 non-Hispanic white teenagers.&lt;/p&gt;
&lt;p&gt;A breakdown by state revealed that New Mexico had the highest teenage pregnancy rate, followed by Nevada, Arizona, Texas, and Mississippi.&lt;/p&gt;
&lt;p&gt;Conversely, the lowest teenage pregnancy rate was in New Hampshire  --  33 pregnancies per 1,000  --  followed by Vermont, Maine, Minnesota, and North Dakota.&lt;/p&gt;
&lt;p&gt;Texas had the highest rate of births to teenage mothers  --  62 per 1,000  --  and New York had the highest rate of abortions among teenagers, 41 per 1,000.&lt;/p&gt;
&lt;p&gt;The report was based on data from the National Center for Health Statistics of the U.S. Department of Health and Human Services (number of births), the Guttmacher Institute (total number of abortions), the U.S. Centers for Disease Control and Prevention (age and race/ethnicity distribution of women obtaining abortions), and the Population Estimates Program of the U.S. Bureau of the Census in collaboration with NCHS (population estimates).&lt;/p&gt;
&lt;p&gt;Among other findings in the report: &lt;ul&gt; &lt;li&gt;The pregnancy rate was 71.5 pregnancies per 1,000 girls ages 15-19 and pregnancies occurred among 7% of females in this age group.&lt;/li&gt; &lt;li&gt;Although teenage abortions increased by 1% from 2005 to 2006, the overall teenage abortion rate declined by about a third over the two decades from 1986 to 2006.&lt;/li&gt; &lt;li&gt;The increase in teen pregnancies and births to teenage mothers was observed across all racial and ethnic groups.&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The authors said that additional research was needed to determine if the disparities in rates by both race and region carry over to adult women.&lt;/p&gt;

                     score="0.002"
                     href="http://www.medpagetoday.com/Endocrinology/GeneralEndocrinology/tb/18149?impressionId=1265795209460"
                     
      &lt;p&gt;Women taking selective serotonin reuptake inhibitor (SSRI) antidepressants may experience delays in postpartum breast milk production, researchers said.&lt;/p&gt;
&lt;p&gt;Delayed secretory activation occurred in 87.5% of a small group of women taking SSRIs, compared with 43.5% of those not taking the drugs (RR 2, 95% CI 1.51 to 2.67, &lt;em&gt;P&lt;/em&gt;=0.02), according to Aaron M. Marshall, PhD, of the University of Cincinnati.&lt;/p&gt;
&lt;p&gt;The relative risk of delayed activation remained significantly higher (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05) among SSRI users after adjustment for maternal age, obesity, cesarean delivery, infant gestational age, and infant breastfeeding behavior, the researchers reported online in the &lt;em&gt;Journal of Clinical Endocrinology and Metabolism&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;An early breastfeeding difficulty faced by many women, particularly those who are primiparous, is milk secretion delayed beyond 72 hours postpartum.&lt;/p&gt;
&lt;p&gt;These women also are at risk of early cessation of breastfeeding. In fact, only 11% of mothers in the U.S. breastfeed exclusively for the recommended six months.&lt;/p&gt;
&lt;p&gt;Studies in animal models and cell cultures suggested that serotonin (5-HT) is an important local regulator of lactation homeostasis, and the 5-HT transporter is expressed in mammary tissue at the apical membrane of epithelial cells.&lt;/p&gt;
&lt;p&gt;Serotonin is controlled intracellularly by a balance between synthesis and degradation, while extracellularly its availability is controlled through recycling by the 5-HT transporter.&lt;/p&gt;
&lt;p&gt;The 5-HT transporter also is the target for the most commonly prescribed class of antidepressants in the U.S. and other developed countries. These SSRI antidepressants are typically used to treat postpartum depression.&lt;/p&gt;
&lt;p&gt;The investigators conducted in vitro and animal studies to establish that the 5-HT transporter is expressed in breast tissue, particularly in the apical membranes of mammary epithelial cells, and that pharmacologic inhibition of the transporter disrupts tight junctures leading to a local involution-like effect.&lt;/p&gt;
&lt;p&gt;To examine the potential effect of SSRI inhibition on milk production in women, Marshall and colleagues enrolled 431 mothers as part of a longitudinal cohort study examining barriers to early lactation success.&lt;/p&gt;
&lt;p&gt;All were expecting their first live-born infants, had no known absolute contraindication to breastfeeding, and were at least 19 years old.&lt;/p&gt;
&lt;p&gt;Women taking SSRIs were more likely to have scored higher on a depressive symptom scale (as expected), and were somewhat more likely to be obese or to have had a cesarean delivery.&lt;/p&gt;
&lt;p&gt;Participating mothers were visited between 72 and 96 hours after giving birth to assess their breastfeeding experience and to determine the timing of secretory activation, and then seen again one week later.&lt;/p&gt;
&lt;p&gt;Delayed secretory activation was defined as initiation more than 72 hours postpartum.&lt;/p&gt;
&lt;p&gt;Median onset of secretory activation among the SSRI-treated mothers was 85.8 hours compared with 69.1 hours in mothers not using the drugs (&lt;em&gt;P&lt;/em&gt;=0.004).&lt;/p&gt;
&lt;p&gt;Eight women reported regular use of an SSRI medication. Seven experienced definite delayed secretory activation, and the eighth reported activation at 72 hours and therefore did not meet the defined cutoff for delayed activation.&lt;/p&gt;
&lt;p&gt;All women taking SSRIs had experienced secretory activation by their second visit a week after the first interview.&lt;/p&gt;
&lt;p&gt;The researchers noted that most studies on the effects of SSRI use during pregnancy and lactation have focused on the risks for developmental defects or whether the drugs passed into milk during lactation.&lt;/p&gt;
&lt;p&gt;This study, they said, is the first to report data on another important aspect of SSRI use during the peripartum, the effect on milk production.&lt;/p&gt;
&lt;p&gt;They concluded that the risk of delayed secretory activation was twice as great among primiparous women using an SSRI medication, and although the fraction of women taking the drugs was small, the risk was significant and remained so after adjustment for potential confounding factors.&lt;/p&gt;
&lt;p&gt;Further examination of this relationship is needed in larger groups of mothers, the researchers said, and in studies to determine if there are differences among the antidepressant medications.&lt;/p&gt;

                     score="-0.003"

      &lt;p&gt;Pregestational maternal diabetes was associated with an increased risk of a major congenital anomaly, but obesity itself was not, a cross-sectional study found.&lt;/p&gt;
&lt;p&gt;In a multivariable logistic model, the major contributor to a rising rate of congenital anomalies was maternal pregestational diabetes (OR 3.8, 95% CI 2.1 to 6.6), according to Joseph R. Biggio, Jr., MD, and colleagues from the University of Alabama at Birmingham.&lt;/p&gt;
&lt;p&gt;&quot;Because hyperglycemia is a major contributor to developmental malformations, interventions to address obesity and identify women at risk for diabetes and hyperglycemia should be considered in efforts to reduce the occurrence of congenital anomalies,&quot; they wrote in the February issue of &lt;em&gt;Obstetrics &amp;amp; Gynecology.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Maternal obesity has been linked with numerous problems, including preeclampsia, gestational diabetes, fetal and neonatal death, and birth trauma, but scientists have disagreed over whether it also contributes to the risk of fetal malformations, the researchers noted.&lt;/p&gt;
&lt;p&gt;To help settle the issue, Biggio and colleagues used a perinatal database in their university health system that included all women with singletons delivered between 1991 and 2004.&lt;/p&gt;
&lt;p&gt;They divided the cohort into three time periods  --  1991 to 1994, 1995 to 1999, and 2000 to 2004, with a total of 41,902 pregnancies.&lt;/p&gt;
&lt;p&gt;For their primary analysis, they defined maternal obesity as a first prenatal visit weight greater than 200 lb, because during the earlier epochs many women did not have body mass index (BMI) calculated. For their secondary analyses they used BMI greater than 29 kg/m&lt;sup&gt;2&lt;/sup&gt; as the criterion for obesity.&lt;/p&gt;
&lt;p&gt;In each epoch, there were increases in mean maternal weight, mean BMI, the proportion of women weighing more than 200 lb, the proportion with a BMI greater than 29 kg/m&lt;sup&gt;2&lt;/sup&gt;, and the prevalence of pregestational diabetes (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for all).&lt;/p&gt;
&lt;p&gt;Univariable analysis determined that the rate of major anomalies, particularly involving the cardiac and pulmonary systems, also increased during each time period.&lt;/p&gt;
&lt;p&gt;But there was no independent association between congenital anomalies and maternal obesity using either definition, during any of the three time periods or during the study overall.&lt;/p&gt;
&lt;p&gt;Although no direct association was seen between congenital malformations and maternal obesity, the investigators reported that the proportion of anomalies that could be attributed to obesity increased from 0% to 23% during the overall study period.&lt;/p&gt;
&lt;p&gt;The proportion of anomalies that could be attributed to diabetes ranged from 58% to 76%.&lt;/p&gt;
&lt;p&gt;Moreover, for obese women with diabetes the proportion of anomalies attributed to diabetes increased sharply, from 48% in the first epoch to 74% in the third epoch.&lt;/p&gt;
&lt;p&gt;In contrast, for the obstetric population as a whole, the population-attributable risk of congenital malformation related to obesity rose from near zero in the first epoch to 6.1% in the third epoch, while that related to diabetes increased from 3.3% to 9.2%, the investigators reported.&lt;/p&gt;
&lt;p&gt;During the course of the study there was a nearly 15-lb increase in maternal weight and a 30% increase in the proportion of women whose BMI exceeded 29 kg/m&lt;sup&gt;2&lt;/sup&gt;.&lt;/p&gt;
&lt;p&gt;There also was a nearly twofold increase in the rate of major anomalies  --  and a 250% increase in the prevalence of diabetes.&lt;/p&gt;
&lt;p&gt;The authors observed that there has been much interest in the effects of maternal obesity on birth defects.&lt;/p&gt;
&lt;p&gt;Although the pathophysiologic basis for this possible association have not been identified, hypotheses have included increased serum insulin, lower levels of folic acid, chronic hypoxia, and increased inflammatory mediators.&lt;/p&gt;
&lt;p&gt;&quot;Our study provides evidence that the defects may not be due solely to the maternal obesity per se but may be due to undiagnosed diabetes,&quot; the investigators wrote.&lt;/p&gt;
&lt;p&gt;From a public health standpoint, the study findings suggest that efforts to reduce the prevalence of congenital anomalies should be focused less on obesity and aimed more closely at correcting hyperglycemia.&lt;/p&gt;
&lt;p&gt;&quot;If euglycemia could be achieved before pregnancy, or at least embryogenesis and organogenesis, the majority of these anomalies could potentially be avoided,&quot; they observed.&lt;/p&gt;
&lt;p&gt;They also suggested that even women of normal weight, but with other diabetes risk factors, could benefit from closer attention to glycemic control.&lt;/p&gt;
&lt;p&gt;A weakness of the study was the fact that detailed data on glycemic control was not available in the perinatal database, &quot;and therefore we cannot comment on the association between glycemic control and anomaly rates,&quot; the investigators wrote.&lt;/p&gt;
