Familial aggregation of body mass index and subcutaneous fat measures in the longitudinal Québec family study.

Family resemblance for several measures of body fat and fat distribution was explored in the longitudinal Québec Family Study (QFS), including an overall measure of adiposity (body mass index, BMI), total subcutaneous fat (the sum of 6 skinfolds, SF6), and subcutaneous fat distribution (the trunk to extremity ratio, TER). Repeated measures were taken twice approximately 12 years apart. A longitudinal familial correlation model was used to assess familial resemblance at each of times 1, 2, and cross-time, and a univariate model was used for the change score. The change score was assumed to index the degree to which different familial factors impacted on the longitudinal resemblance, while the cross-time comparisons indexed similar familial factors across time. For BMI, the maximal heritability was 44 and 36% at times 1 and 2, respectively, 37% for the change score, and 33-43% for the cross-time comparison. While the etiology of the BMI familial effect at times 1, 2, and cross-time was assumed to be primarily polygenic, that for the change score was a function of cohort effects (environmental). For SF6, the maximal heritability (primarily genetic) was low at time 1 and for the change score (16%), but was nonsignificant at time 2 and cross-time. For TER, the maximal heritabilities were significant for each of times 1 (42%), 2 (40%), change score (59%), and cross-time comparisons (35-36%). In summary, simple univariate familial correlation analysis of the change scores and bivariate analysis of the longitudinal measures are useful in delineating the underlying factors leading to both change and stability across time.

Families and hospitalized elders: A typology of family care actions.

The extensive care provided by families to their elderly relatives in the home is well documented. Although family caregiving is likely to be continued during hospitalization of elderly relatives, limited research has been conducted to address the nature of family care for hospitalized elders. The main purpose of this qualitative study was to refine the content domain of family care for hospitalized elders. Altogether 25 interviews were done. Of the 16 participants, 6 were family members, 6 were patients, and 4 were nurses; 7 participants were interviewed once and 9 participants were interviewed twice. Qualitative analysis based on Lofland and Lofland's (1984, 1995) approach resulted in the identification of three major content domains: family members providing care to the patient, working together with the health care team, and taking care of themselves. This typology suggests a shift of research in this area from its current focus on family needs to a view of family caregivers as partners with the health care team.

Familial clustering of colon, breast, uterine, and ovarian cancers as assessed by family history.

The aggregation of colon, endometrial, ovarian, and possibly breast cancers in families has been described as a "cancer family syndrome" (now called Lynch syndrome II). To determine if the familial clustering of these malignancies was more common in women with cancer than without, we analyzed data from the Iowa Women's Health Study (IWHS), a population-based sample of 41,837 women aged 55-69 years. Self-reported information was collected on history of colon, uterine, ovarian, and breast cancers in female first-degree relatives. A family history of cancer of the breast (odds ratio [OR] = 1.4), colon (OR = 1.3), and uterus (OR = 1.3), but not ovary (OR = 1.2), was significantly more common among women with a personal history of any of these four cancers (all P < 0.05); the pattern of the ORs suggested strongly that the clustering tended to be site-specific. Age-adjusted relative risks (RR) of incident colon cancer over 5 years of follow-up (N = 237) were calculated with regard to family history. Colon cancer incidence was increased among women with a family history of breast (RR = 1.3), uterine (RR = 1.4), colon (RR = 1.5), and ovarian (RR = 1.3) cancers, although none of the risk estimates achieved statistical significance. RR was, however, significantly related to the number of different cancer sites reported among family members (Ptrend = 0.008). These data on a representative sample of postmenopausal women suggest that family histories of colon, breast, uterine, and ovarian cancers are associated with an increased risk of cancer at the same site, but provide little support for the hypothesis that Lynch syndrome II is a non-random occurrence.

Effects of a family intervention on the quality of life of women with recurrent breast cancer and their family caregivers.

BACKGROUND: The purpose of this study was to determine if patients with advanced breast cancer and their family caregivers, who participated in a family based intervention, report better quality of life and other psychosocial outcomes than dyads who received standard care alone. METHODS: Using a randomized clinical trial, 134 patients and their family caregivers were assigned to usual care (control) or to usual care plus the family intervention (experimental condition). Dyads were assessed at baseline, three- and six-months later. The intervention consisted of five sessions and addressed family involvement, optimistic attitude, coping effectiveness, uncertainty reduction, and symptom management. RESULTS: Patients in the family intervention reported significantly less hopelessness and less negative appraisal of illness than controls; their family caregivers reported significantly less negative appraisal of caregiving. Intervention effects were evident at three-months, but were not sustained at six-months. No difference was found in the quality of life of dyads in experimental or control conditions. CONCLUSIONS: Although the family intervention had positive effects initially, these effects were not sustained over time. Future studies need to consider program dose and duration of effect, outcome measures that are more sensitive to change, and realistic end-points for patients with advanced cancer.

A comparison of how families and their service providers rate family generated quality of service factors.

This paper presents a method which was utilized to obtain family consensus around the criteria which should be used to evaluate family support programs. Twelve family members of persons with developmental disabilities were selected in each of six different sites to participate in a group process to identify the factors which distinguish quality family support programs. Content analysis of the results of the six meetings resulted in a final list of 15 quality factors. Two hundred and sixty one families and their family support coordinators (N = 65) were asked to rate the importance of each factor on a 10 point scale. Analysis revealed that there was high agreement between families and their coordinators on the importance of all 15 factors. The applicability of the method used to obtain family consensus regarding evaluation criteria for community mental health agencies is discussed.

Family stress, family functioning and emotional/behavioural problems following child psychiatric treatment.

This study assesses family stress, family functioning and emotional/behavioural problems in a sample of 80 formerly daytreated or residentially treated boys after a mean discharge period of four years. Family stress was assessed with a Questionnaire of Life Events (QLE) and family functioning with the Family Adaptability and Cohesion Evaluation Scales (FACES). Emotional/behavioural problems were measured with the Child Behavior Checklist (CBCL). The results showed that there were significant relationships between the QLE, FACES and CBCL scores. In particular, experiencing less negative life events and a more rigid type of family functioning appeared favourable with respect to several types of behavioural problems. When the interrelationships between the family factors and other factors such as age and socio-economic status were taken into account statistically, the number of negative life events appeared the most influential family factor.

The Family Strain Index (FSI). Reliability, validity, and factor structure of a brief questionnaire for families of children with ADHD.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) in children affects every member of the family. Practical tools are needed to assess the effects of ADHD on families to better understand and address the level of stress, strain and burden that families experience. OBJECTIVE: To provide the preliminary reliability, validity and factor structure of the Family Strain Index (FSI), a 6-item parent-report questionnaire. METHODS: The FSI was completed by 1,477 parents of children with ADHD (aged 6-18 years) at the baseline visit of the ADORE study in 10 European countries (data missing for one patient). RESULTS: The FSI taps into an overall experience of worry and interruptions of activities in families of children with ADHD, as a single factor was identified with excellent internal consistency (alpha=0.87). Despite its brevity, almost no ceiling (worst score) or floor (best score) effects were observed for families of these highly symptomatic children. This score distribution and the 5-point response options suggest that the FSI will be responsive to changes in the experience of family strain associated with children's ADHD treatment. CONCLUSION: The ease of completion and coherence of the underlying construct indicates that the FSI may be a practical clinical tool for monitoring changes in family strain associated with children's ADHD treatment.

Family history of coronary heart disease is a stronger predictor of coronary heart disease morbidity and mortality than family history of non-insulin dependent diabetes mellitus.

The aim of this study was to compare the effect of family history of non-insulin dependent diabetes mellitus (NIDDM) and coronary heart disease (CHD) as risk factors for CHD morbidity and mortality. Altogether, 394 siblings of NIDDM probands and non-diabetic probands, with and without CHD, were followed for 8 years with respect to CHD events in a prospective population-based study. The baseline study was conducted from 1983 to 1985. Age- and sex-adjusted cumulative occurrence of CHD events was higher in the siblings of the probands with CHD and with NIDDM (13.1%; P = 0.037) and in the siblings of the probands with CHD and without NIDDM (15.4%; P = 0.054), compared with the siblings of the probands without NIDDM and without CHD (4.8%). The incidence of fatal CHD events tended to be higher in a group with a family history of NIDDM and CHD, but the trend was not statistically significant. In univariate logistic regression analyses, a family history of CHD was positively associated with cumulative occurrence of CHD events (odds ratio 2.53, P = 0.009), whereas a family history of NIDDM had no significant association (odds ratio 1.39, P = 0.312). After adjustment for age, sex, family history of NIDDM and major cardiovascular risk factors, the association between family history of CHD and cumulative occurrence of CHD events remained significant (odds ratio 2.25, P = 0.048). In conclusion, the present study indicates that a family history of CHD is a stronger predictor of future CHD events than a family history of NIDDM.

Attitude towards family planning in Dharan, east Nepal: implications for the family planning programme.

A survey of the knowledge, attitude and practice of family planning was conducted in Dharan, Nepal. The town offers a full range of family planning services free of charge. There was a strong desire to limit family size; 52.5% of couples were currently using some modern method of family planning. Of the current users, 62.3% had been sterilized, including 92.3% of those in the lowest socioeconomic group. Health risks and incompleteness of the family were the most common reasons for non-use of contraception, the latter reason reflecting ignorance of the temporary nature of some methods. There was a strong preference for male children and couples rarely used contraception until at least one so had been born. Even in this prosperous town where couples were highly motivated towards family planning and all methods were readily available, there was heavy reliance on sterilization. This is typical of Nepal and has largely been responsible for the failure of the family planning programme--as most couples choosing sterilization are in the older age group and have completed a relatively large family. If Nepal is to succeed in meeting its target of reducing the total fertility rate (i.e., births per woman) from the current 5.8 to 4 by the year 2000 it will need not only to expand services but actively to promote temporary methods of contraception, particularly the more reliable longer acting reversible methods such as Depo-Provera, Norplant and intrauterine contraceptive devices.

Engaging the families of substance abusing adolescents in family therapy.

This article discusses three major topics: First, the family processes one typically finds in families with a substance abusing adolescent are described. These processes include pseudo-separation and defensive delineation. A case vignette is used to illustrate these processes. Second, an overview of the importance of family therapy in treating substance abusing adolescents is provided. Third, specific principals and techniques for involving families in family therapy are described. This area includes a discussion of such topics as using the initial telephone contact to join with and involve the family, and suggestions for handling some typical problems which the therapist may encounter in the initial interview. These problems or resistances must be handled sensitively if the family is to remain in treatment. This is an important area since involving the families of substance abusing adolescents in treatment can be quite difficult and there is little practical literature available.

Genetic polymorphisms of alcohol and aldehyde dehydrogenase, dopamine and serotonin transporters in familial and non-familial alcoholism.

One hundred and eleven male patients with alcohol dependence and 123 nonalcoholic healthy men were tested for the genetic polymorphisms of alcohol dehydrogenase 2 (ADH2), aldehyde dehydrogenase 2 (ALDH2), serotonin transporter (5-HTT) and dopamine transporter (DAT1). There were significant differences in genotype frequencies of ADH2 C992G and A13543G SNPs between alcoholic patients with family history of alcohol dependence (familial) and alcoholic patients without family history (non-familial). Genotype and allele frequencies of ALDH2 G1951A SNP in familial or non-familial alcoholic patients differ from normal controls. Neither 5-HTTLPR L/S nor DAT1 G2319A SNP genotypes nor alleles discriminated alcoholic patients from normal controls. These findings suggest that the genetic characteristics of alcohol metabolism in non-familial alcoholics fall between non-alcoholism and familial alcoholics.

School-age and adolescent children's perceptions of family functioning in neglectful and non-neglectful families.

OBJECTIVE: Examined the question, do neglected children's perceptions of their own family's functioning acknowledge the differences that exist between neglectful and non-neglectful families? METHOD: An inter-rater consistency design was used; child and caseworker reports of family functioning in neglectful (n = 33) and non-neglectful families (n = 34) were compared. RESULTS: After establishing significant differences between the socioemotional and physical environment provided by neglectful and non-neglectful families, the results indicated that children from neglectful families perceived a higher level of quality in family functioning that was not reported by caseworkers or supported by other measures. CONCLUSIONS: Implications for designing effective interventions for school-age and adolescent children from neglectful families are discussed.

The cadherin-related neuronal receptor family: a novel diversified cadherin family at the synapse.

The cadherin-related neuronal receptor (CNR) family has been identified as a receptor family that cooperates with Fyn, a member of the Src family of tyrosine kinases. The CNR family is composed of 14 members in mice and 15 members in humans. The mRNAs of CNRs are highly expressed in the brain and CNR1 protein is localized at synaptic junctions. Hence CNR family proteins are synaptic cadherins. The unique structure of CNR family cDNAs, which is characterized by complete DNA sequence identity among their 3'-termini including a part of the coding region, prompted us to investigate the genomic organization of this family. The genomic organization of CNRs is divided into 'variable' and 'constant' region exons, analogous to immunoglobulin and T cell receptor gene clusters. This organization raised the possibility that the CNR gene cluster may undergo somatic DNA rearrangement or trans-splicing and produce diversified gene products. Although it is not yet clear that the CNR gene cluster in the neuronal genomic DNA is somatically changed, a recent study suggested the occurrence of trans-transcripts and accumulation of somatic mutations in CNR transcripts (Genes Cells 6 (2001) 151). These results suggested that the proteins from the CNR gene cluster are enormously diversified by unique mechanisms. The localization of CNR1 protein at the synapse and the diversity of CNRs led us to the hypothesis that gene regulation of the CNR family dictates the formation and reorganization of synaptic connections in the nervous system.

Validation of family history data in cancer family registries.

BACKGROUND: Although family history information on cancer is used to infer risk of the disease in population-based, case-control, cohort, or family-based studies, little information is available on the accuracy of a proband's report. In this study, we sought to determine the validity of the reporting of family history of cancer by probands in population-based and clinic-based family registries of breast, ovarian, and colorectal cancers. METHODS: To assess the accuracy of probands' reported family history of cancer in their relatives, we compared the family history from the personal interview of each proband to a reference standard that included pathology reports, self-reports, or death certificates on the relatives. Our study included 1111 families that accounted for 3222 relatives who were verified. To account for within-family correlations in the responses, we used a generalized estimating equation approach. RESULTS: The probability of agreement between the proband-reported cancer status in a relative with the reference standard varied by cancer site and by degree of relationship to the proband. This probability for first-degree relatives was 95.4% (95% confidence interval [CI]=92.6-98.3) for female breast cancer; 83.3% (95% CI=72.8-93.8) for ovarian cancer; 89.7% (95% CI=85.4-94.0) for colorectal cancer; and 79.3% (95% CI=70.0-88.6) for prostate cancer. CONCLUSIONS: We found high reliability of probands' reporting on most cancer sites when they reported on first-degree relatives and moderate reliability for their reporting on second- and third-degree relatives. Overreporting of cancer was rare (2.4%). Race or ethnicity and gender of the proband did not influence the accuracy of reporting. However, degree of relationship to the proband, type of cancer, age at diagnosis of the proband, and source of ascertainment of probands were statistically significant predictors of accuracy of reporting.

Familial dyslipidemic hypertension syndrome: familial combined hyperlipidemia, and the role of abdominal fat mass.

Familial combined hyperlipidemia (FCHL) is the most frequent genetic lipid abnormality in humans, with a 5- to 10-fold increased risk of early myocardial infarction. Familial combined hyperlipidemia has been proposed as the leading cause of dyslipidemia in familial dyslipidemic hypertension (FDH). It was the objective of this study to quantify and analyze the simultaneous occurrence of hypertension and hyperlipidemia in FCHL families. We assessed blood pressure (BP) and hyperlipidemia in 27 families with FCHL (235 relatives and 140 spouses, aged 30 to 60 years). Hypertension was defined as a BP more than 140/90 mm Hg, or the use of antihypertensive medication. Multiple backward linear regression analysis was used to derive a biological formula describing BP in FCHL families. One-third of 27 FCHL families were diagnosed with FDH. Sixty-four of 235 (27.2%) relatives had dyslipidemic hypertension (DH), compared to 20 of 140 (14.3%) spouses (P = .005); odds ratio = 2.25 (95% confidence interval 1.29-3.91). Multiple linear regression analysis showed that age, FCHL status, and waist circumference significantly contributed to systolic blood pressure (SBP) in female FCHL relatives. In conclusion, in FCHL we defined age, waist circumference, and hyperlipidemia as predictors of SBP. This study indicates that visceral adipose tissue strongly contributes to the high prevalence of DH in FCHL families. Reduction of visceral fat should be tested as a potential therapeutic intervention for hyperlipidemia and hypertension in FCHL individuals.

ICU family support group sessions: family members' perceived benefits.

The purpose of this research was to identify the relationship between attending an ICU family support group and the family's appraisal of stress, social support, and hope. In addition, the family members' perceived benefits of attending an ICU family support family support group session does not significantly change stress levels, feelings of hope, and social support. Analysis of data reconfirms that family members of critically ill patients have a tremendous need for information. Although findings revealed that the majority of the family members who attended the support session would recommend attending again, it is unclear whether the support session method is the most beneficial and cost-effective means to support families of critically ill patients.

Are families with adolescents and young adults with cerebral palsy the same as other families?

This study compared adolescents with cerebral palsy (CP) and their families to adolescents without physical disabilities and their families as the child enters and leaves adolescence (age ranges 13 to 15 years and 19 to 23 years). Families of 90 individuals with CP (42 females, 48 males) and 75 individuals without physical disabilities (34 females, 41 males) participated. They completed the Family Assessment Device, Life Situation Survey, Multidimensional Scale of Perceived Social Support, and Future Questionnaire. There were few differences in family functioning, life satisfaction, or perceived social support between the groups. Expectations of young adults with CP and parents of both adolescents and young adults regarding future independence and success were lower than the expectations of the control group. While the group results emphasize similarities between families during the two stages of adolescence, individual families and individual family members report specific challenges.

Familial aggregation for conduct disorder symptomatology: the role of genes, marital discord and family adaptability.

BACKGROUND: There is extensive evidence of statistical associations between family discord/ maladaptation and antisocial behaviour in the children, but questions remain on the extent to which the psychopathological risks are genetically or environmentally mediated. METHODS: Twin pairs (N = 1,350), aged 8 to 16 years, in the general population-based Virginia Twin Study of Adolescent Behavioral Development were assessed using the Child and Adolescent Psychiatric Assessment interview administered separately to both twins and both parents. Structured interviews for parental lifetime psychiatric disorders were also administered to the mothers and fathers. Maternal reports on Olsson's Family Adaptability and Cohesiveness questionnaire and the Dyadic Adjustment Scale were used as indices of the family environment. A path analytical model based on an extended twin-family design was used to test hypotheses about parent offspring similarity for conduct disorder symptomatology. RESULTS: Family discord and maladaptation, which intercorrelated at 0.63, were associated with a roughly two-fold increase in risk for conduct disorder symptomatology. When parental conduct disorder was included in the model the environmental mediation effect for family maladaptation remained, but that for family discord was lost. CONCLUSION: It is concluded that there is true environmental mediation from family maladaptation, operating as a shared effect, which accounts for 3.5 % of the phenotypic variance. The assumptions underlying this genetic research strategy are made explicit, together with its strengths and limitations.
