Abstract P6-10-17: Psychosocial adjustment, cancer worry and perceived risk in 6-13 year old girls from breast cancer families

Abstract

Abstract Background: Many parents discuss familial and genetic risk of breast cancer (BC) with offspring. What girls know and perceive of BC risk and its psychosocial impact is unknown. Methods: In the multisite LEGACY Girls Study, 6-13 YO daughters and their parents/guardians from BC families (FH+) and families without BC (FH-) were recruited to examine early determinants of, and responses to BC risk. Parents/guardians completed surveys reporting on their daughters’ psychosocial adjustment (PSA). Mothers and daughters 10-13 YO completed surveys reporting their PSA and perceptions of breast cancer risk. We used linear and logistic regressions with variable selection. Results: 731 parents/guardians reported on their own and the PSA of 898 daughters (450 FH+, 448 FH-), and 447 girls (10-13 YO) completed surveys (227 FH+, 220 FH-). FH+ girls have lower somatization and internalizing behaviors by parent/guardian report than FH- girls (Table 1). Intrusive BC (IBC) worry, and avoidant BC (ABC) worry were significantly higher in FH+ girls. IBC worry (coef=0.8, p=0.04) and ABC worry (coef 1.8, p=0.007) were higher in daughters whose mother had BC. Daughter perceived stress (PS), anxiety, depression, somatization, and internalizing did not differ by mother BC history. In multivariable models, daughter-anxiety was associated with mother-anxiety (Coef 1.4, p<0.0001) and BRCA+ family (coef -13.5, p=0.040). Daughter-depression was associated with mother-anxiety (coef 1.0, p=0.009). Daughter-IBC worry was associated with mother-IBC worry (coef 0.2, p<0.001). Daughter-ABC worry was associated with mother-IBC worry (coef 0.2, p=0.002) and being FH+ (coef 1.3, p=0.02). Daughter-PS was associated with mother-depression (coef 0.2, p=0.003). Somatization was not associated with any variables in multivariable models. FH+ girls were more likely to report themselves at higher risk for BC, although many reported uncertainty about their own BC risk.

Daughter general anxiety, depression and BC worry are associated with corresponding mother affect. Some girls from BC families are aware of their increased risk and related research suggests this may increase with age. Understanding how PSA and BC worry changes over time and the impact on health and risk behaviors can inform interventions to optimize responses to growing up in families at familial and genetic risk for breast cancer.
