Psychosocial factors in the progression of cervical intraepithelial neoplasia--CIN

Life Stressors Are an Important Reason for Women Discontinuing Follow-up Care for Cervical Neoplasia

Although studies have addressed psychosocial factors associated with obtaining follow-up care for an abnormal Pap test, none have explored the effect of stressful life events in predicting the receipt of follow-up care for an abnormal Pap test. Data from a program (1995-2001) that provided free follow-up care for women with low-grade cervical lesions (n = 601) was used to determine whether life stressors increased risk of study discontinuation. Women were interviewed at baseline and offered follow-up at 4- to 6-month intervals for up to 24 months. Of the 556 women recruited and interviewed (92% response rate), 53 were referred out because they had high-grade cervical lesions and 33 had a health condition precluding follow-up. Among 470 women who began follow-up, 175 (37.2%) discontinued before completing three visits. Women who discontinued were significantly more likely to report more stressful life events in the past year [age-adjusted relative risk (aRR), 1.19; 95% confidence interval (95% CI), 1.08-1.30; 17-item scale]. Events most strongly associated with discontinuation included having a problem with a boss (aRR, 1.9; 95% CI, 1.5-2.4), severe physical partner violence (aRR, 1.7; 95% CI, 1.3-2.2), being homeless (aRR, 2.1; 95% CI, 1.6-2.8), and having an unplanned pregnancy (aRR, 1.5, 95% CI, 1.2-2.1). Life stressors may be important predictors of discontinuation of free follow-up care among women in need of immediate follow-up care to prevent lesion progression.

The effects of avoidance on cytotoxic/suppressor T cells in women with cervical lesions

The purpose of this study was to examine the relationship between avoidant and intrusive ideation about cancer risk and immune responses among women with mild cervical dysplasia. Participants were 54 women undergoing diagnostic follow-up (i.e. colposcopy) for an abnormal Pap smear test result. Baseline assessments, collected prior to the colposcopy appointment, included demographic and medical history, levels of depression, and the intrusion and avoidance subscales of the Revised Impact of Events Scale. In addition, a sample of blood was obtained at baseline and 6-month follow-up for immune assessments. Hierarchical regression analyses revealed that higher levels of cognitive and behavioral avoidance at baseline predicted a significantly lower percentage of circulating cytotoxic/suppressor T cells (CD3(+)/CD8(+)) at 6-month follow-up, after controlling for baseline levels of cytotoxic/suppressor T cells and potential confounding variables (e.g. age, smoking status). Baseline intrusive ideation was unrelated to changes in percentage of cytotoxic/suppressor T cells. Avoidant ideation, but not intrusive ideation or depression, appears to be associated with alterations in immunologic measures in women with cervical lesions. The findings suggest that it may be important to evaluate the impact of cognitive and behavioral avoidance on progression of precancerous cervical lesions.

Psychosocial stress and cervical neoplasia risk

OBJECTIVE

We assessed the association between psychosocial stress and preinvasive cervical neoplasia development controlling for HR-HPV infection.

METHODS

This case-control study enrolled low-income women receiving family planning services at health department clinics. There were 59 cases with biopsy confirmed HSIL and 163 with low-grade SIL and 160 controls with normal cervical cytology. A modified SLE scale was used to measure stressful events and the perceived impact of the event in the prior 5 years. Unconditional logistic regression was used to assess SIL risk and stressful events scores and by subscales.

RESULTS

After adjusting for age, HR-HPV infection, and lifetime number of sex partners, the SLE count score was associated with an increased risk of SIL among white women (aOR = 1.20; 95% CI = 1.04, 1.38) yet not among African American women (aOR = 1.02; 95% CI = 0.87, 1.19). The relationship stress subscale (divorce, infidelity, an increase in the number of arguments, and psychological and physical partner violence) was the only one of four subscales (loss, violence, and financial stress) associated with SIL, again, only among white women (aOR = 1.54; 95% CI = 1.21, 1.96).

CONCLUSIONS

These data suggest that psychosocial stress may play a role in SIL development. Future studies are needed to confirm these findings, to explore racial difference in reporting stress, and to explore the mechanism through which psychosocial stress may affect cervical neoplasia risk.

Association between subjective sleep quality and depression on immunocompetence in low-income women at risk for cervical cancer

OBJECTIVE

The purpose of this study was to investigate whether subjective sleep quality is more strongly associated with immunocompetence than depression among women at risk for cervical cancer.

METHODS

Participants were 91 women referred for colposcopy because of abnormal results on a Pap smear. On the day of the procedure. participants completed the Center for Epidemiological Studies Depression Scale, two indices of subjective sleep quality (ie, satisfaction with sleep obtained and degree of sleep restfulness), and a health behaviors assessment questionnaire. Levels of peripheral blood lymphocyte subpopulations (helper T, cytotoxic/suppressor T, NK, and B cells) were also assessed at this time. Approximately 10 days later, the presence of depressive disorder was assessed using the Structured Clinical Interview for DSM-III-R.

RESULTS

Hierarchical regression analyses revealed that satisfaction with the amount of sleep obtained was significantly associated with the circulating number and percentage of helper T cells (T(H)/CD4+) and the percentage of cytotoxic/suppressor T cells (T(C)/CD8+), after controlling for confounder variables (ie, age, smoking status, and drug use). Depression was significantly associated only with the percentage of T(C) cells. Sleep satisfaction remained significantly associated with the number and percentage of T(H) cells and percentage of T(C) cells after controlling for the variance explained by depression.

CONCLUSIONS

Results of this study suggest that subjective sleep quality shares a significant and independent portion of the variance with immunity that is not accounted for by depression. Although the long-term impact of these immune alterations on disease progression needs to be directly explored, it may be important to systematically screen for and manage sleep disturbance in women at high risk for cervical cancer.
