Perceived Parental Control and Parent–Child Relational Qualities in Early Adolescents In Hong Kong: Parent Gender, Child Gender and Grade Differences

This study examined parent gender, child gender and grade differences in perceived parental control and parent–adolescent relational qualities in early adolescents in Hong Kong, People’s Republic of China. Utilizing a longitudinal research design, 2,559 Chinese secondary school students responded to instruments assessing perceived parental behavioral control, parental psychological control, and parent–child relational qualities over three consecutive years. Results showed that there were parent gender and child gender differences in parental control and parent–adolescent relational qualities, but interaction effects of parent gender and child gender were also found. These findings strongly challenge the traditional Chinese cultural belief of “strict fathers, kind mothers”. Results also consistently showed that the levels of perceived parental behavioral control and parent–child relational qualities gradually declined from grades 7 to 9 in early adolescent years in the Chinese culture.

Maternal family history of Alzheimer's disease predisposes to reduced brain glucose metabolism.

Having a parent affected with late-onset Alzheimer's disease (AD) is a risk factor for developing AD among cognitively normal subjects. We examined whether cognitively normal subjects with a parental family history of AD show cerebral metabolic rate of glucose (CMRglc) reductions consistent with AD as compared with those without a family history and whether there are parent gender effects. Forty-nine 50- to 80-year-old normal subjects were examined who received clinical, neuropsychological, and 2-[(18)F]fluoro-2-deoxy-d-glucose-positron emission tomography examinations, including 16 subjects with a maternal (FHm) and eight with a paternal (FHp) family history of AD and 25 with no family history (FH(-)). FH groups were comparable for demographic and neuropsychological measures. As compared with both FH(-) and FHp groups, FHm subjects showed CMRglc reductions in the same regions as clinically affected AD patients, involving the posterior cingulate cortex/precuneus, parietotemporal and frontal cortices, and medial temporal lobes (P < 0.05, corrected for multiple comparisons). These effects remained significant after accounting for possible risk factors for AD, including age, gender, education, apolipoprotein E genotype, and subjective memory complaints. No CMRglc differences were found between FHp and FH(-) subjects. This study shows a relationship between reduced CMRglc in AD-vulnerable brain regions and a maternal family history of AD in cognitively normal individuals.

Parent psychopathology, parenting, and child internalizing problems in substance-abusing families.

A structural model accounting for child internalizing problems in substance-abusing families was tested. Parents receiving substance abuse treatment (N = 242) completed forms about children between the ages of 6 and 18 who resided in their home. The effects of parent gender, child gender, and child age were controlled. Negative parenting was examined as a mediator between parent internalizing and externalizing problems and child anxiety and affective problems using path analysis. Negative parenting mediated relations only between parent internalizing problems and child affective problems. High-positive involvement moderated relations between parent externalizing problems and child internalizing problems. Relations between parent externalizing problems and child anxiety and affective problems were significant only among families in which high-positive involvement was present.

Child care satisfaction: The effects of parental gender and type of child care used

A survey of 1675 parents of preschool-aged children revealed higher levels of satisfaction with child care provided by relatives and byau pairs in the family’s home as compared to either center-based care or home care providers. Parental satisfaction with these latter two forms of child care did not differ significantly. Mothers in general were more satisfied with their child care than fathers. However, child care satisfaction was a significant predictor of work/family balance for both genders.

Evidence against genetic anticipation in familial colorectal cancer.

Anecdotal reports of hereditary colorectal cancer suggest that genetic anticipation (earlier appearance in successive generations) occurs, but ascertainment bias and cohort effects confound this interpretation. Using approaches that correct for such biases, we examined the age at diagnosis of colorectal cancer from family history questionnaires completed by subjects in the Johns Hopkins Hereditary Colorectal Cancer Registry; 475 parent-offspring pairs in 308 pedigrees were studied. We observed the expected cohort effect among offspring, in that the mean ages at diagnosis of those born before 1921, between 1921 and 1930, and after 1930 were 63 +/- 13 (SD), 57 +/- 10, and 42 +/- 10 years, respectively, while their parents' mean ages were 65 +/- 14, 66 +/- 14, and 58 +/- 15 years, respectively. In the cohort born before 1921, in which observation periods for both parents and offspring were comparable, there was no difference in age at diagnosis by pairwise comparison or life table analysis (P = 0.15 and 0.23, respectively; r = 0.32). Subgroup analysis of 67 pairs from 38 families that met the International Collaborative Group (ICG) criteria for hereditary nonpolyposis colorectal cancer (HNPCC) and of 14 pairs from 7 families with known germline mutations of DNA mismatch repair genes also showed no significant differences (mean age at diagnosis: 56 +/- 14 years for parents and 57 +/- 16 years for offspring from ICG families, and 45 +/- 10 years for parents and 44 +/- 12 years for offspring in families with known mutations). We also found no evidence for effect of parental gender on age at diagnosis in offspring of either gender, nor a secular trend toward younger onset colorectal cancer in this sample. In conclusion, there is no evidence for genetic anticipation or genomic imprinting of age at diagnosis in this sample of colorectal cancer families. Apparent anticipation appears to reflect a birth cohort bias of ascertainment.

Father-mother infant interaction in traditional and nontraditional Swedish families: A longtitudinal study

The effects of parental gender and caretaking role on parental attitudes, parent-infant interaction, infant-parent attachment, infants' sociability with strangers and their parental preferences were examined in a longitudinal study of fifty-one Swedish couples. Fathers who later spent more than a month out of the first nine as primary caretakers were considered involved or nontraditional. The parents were interviewed separately, prenatally, and five months postnatally. Parent-infant interaction was observed, security of attachment and sociability with strangers were assessed, and the infants' parental preferences were determined. Many parental attitudes were stable from the pre-to postnatal interview. Parenthood and work were more highly valued by nontraditional than traditional parents. Regardless of relative involvement in child care, infants directed more affiliative and attachment behaviors to their mothers than to their fathers. No relationship was found between relative parental involvement and the security of infant attachment. There was also no relationship between the security of infant-mother and infant-father attachments.
