The cognitive health and development of boys may be affected by their mothers’ body mass index ( BMI) (体重 指数) while pregnant with them, according to research from Columbia University and the University of Texas at Austin.
The study, which was published in the journal BMC Pediatrics on Friday, observed 368 subjects from low-income African American and Dominican women during the second half of their pregnancies, and then evaluated their children three and seven years later. Researchers found that the sons of women whose BMIs indicated that they were overweight or obese when they became pregnant were more likely to show less developed athletic skills as 3-year-olds and lower intelligence as 7-year-olds compared to boys whose mothers were at “normal” weights during pregnancy.
Among boys, the study found, mothers’ overweight and obesity connected with IQ scores between 4.6 and almost 9 points lower than those of boys whose mothers’ weights were in the “normal” range before pregnancy. Researchers did not observe the same phenomenon among daughters whose mothers had been obese.
“These findings aren’t meant to shame or scare anyone,” Elizabeth Widen, assistant professor of nutritional sciences at UT Austin and one of the study’s co-authors, said in a press release. “We are just beginning to understand some of these interactions between mothers' weight and the health of their babies.”
Why mothers’ obesity appeared to affect childhood IQ was unclear, but earlier research has suggested that there is a relationship between a mother’s diet and her child’s later IQ, according to Columbia University. Researchers did not control for what the mothers ate, the press release noted.
The study’s authors wrote that because childhood IQ has been shown to be an indicator of later success in life, studying how a mother’s obesity could affect the IQ of her child is worthwhile.

My students were taking midterms when my phone erupted with urgent messages. “A student is having a panic attack,” texted a teaching assistant. I ran out of my office, down a flight of stairs and found the student — a pupil in my 350-person organic chemistry class — lying motionless on the ground outside the exam hall. “Did my exam really trigger a panic attack?” I asked myself. “Why am I not prepared to deal with a situation like this?”
It was my first time teaching the course. But I knew that the subject was challenging for my students. This was a source of stress for premedical students in particular, who feared that a low grade in organic chemistry would keep them from getting into medical school.
The following day, I was scheduled to lecture to the same class. I knew that I had to address what had happened during the midterm. So, I started by saying: “I want to take some time today to talk about something important. How many of you think that this is a weed-out course?” Half of my students raised their hands carefully. “I’m sorry to hear that,” I continued. “I want you all to know that I do not consider any of you to be weeds; you all deserve to be here.”
I flashed a slide of flowers in various shapes. I smiled at my students and said: “I think of you as flowers — different flowers with different needs. You may not bloom at the same time, but you will bloom! You may not do well in the midterm exam, but you will learn from your mistakes and do better in the final exam. I believe this. I believe in you.”
From that point on, my office hours were packed. Some asked about lecture topics and study strategies; others opened up about personal issues. I was amazed that a simple, frank discussion in lecture could make such a difference.
1.What made the pupil have a panic attack?
A.Hiding personal issues.

3.Why did the author go to the same class the next day?
A.To give the lesson according to the arrangement.
B.To apologize and explain to the panicked student.
C.To give a speech on what happened in the test.
D.To persuade all the students to stay in the class.
4.Which paragraph mainly shows the author’s encouragement to students?
A.Paragraph 2.
B.Paragraph 3.
C.Paragraph 4.
D.Paragraph 5.
