Individuals scoring poorly on tests of intelligence (IQ) have been reported as having increased risk of morbidity, premature mortality, and risk factors such as obesity, high blood pressure, poor diet, alcohol and cigarette consumption. Very little is known about the impact of parental IQ on the health and health behaviours of their offspring.
We explored associations of maternal and paternal IQ scores with offspring television viewing, injuries, hospitalisations, long standing illness, height and BMI at ages 4 to 18 using data from the National Child Development Study (1958 birth cohort).
Data were available for 1446 mother-offspring and 822 father-offspring pairs. After adjusting for potential confounding/mediating factors, the children of higher IQ parents were less likely to watch TV (odds ratio (95% confidence interval) for watching 3+ vs. less than 3hours per week associated with a standard deviation increase in maternal or paternal IQ: 0.75 (0.64, 0.88) or 0.78 (0.64, 0.95) respectively) and less likely to have one or more injuries requiring hospitalisation (0.77 (0.66, 0.90) or 0.72 (0.56, 0.91) respectively for maternal or paternal IQ).
Children whose parents have low IQ scores may have poorer selected health and health behaviours. Health education might usefully be targeted at these families.
智商（IQ）测试得分较低的个体被报告罹患疾病的风险增加，且存在肥胖、高血压、不良饮食、饮酒和吸烟等风险因素。关于父母的智商对其子女的健康和健康行为的影响，我们知之甚少。
我们利用全国儿童发展研究（1958 年出生队列）的数据，探讨了母亲和父亲的智商得分与子女在 4 至 18 岁时看电视、受伤、住院、长期患病、身高和 BMI 的关联。
共有 1446 对母子和 822 对父子的数据可用。在调整潜在的混杂/中介因素后，高智商父母的孩子看电视的可能性较小（每周观看 3 小时以上与母亲或父亲智商每增加一个标准差相关的比值比（95%置信区间）：0.75（0.64，0.88）或 0.78（0.64，0.95）），且受伤需要住院的可能性较小（每周观看 3 小时以上与母亲或父亲智商每增加一个标准差相关的比值比（0.77（0.66，0.90）或 0.72（0.56，0.91）））。
父母智商得分较低的孩子可能存在某些健康和健康行为较差的情况。健康教育可能对这些家庭很有用。
