The distribution and predictive validity of the stages of change for mammography adoption among Canadian women

Inconsistent Mammography Perceptions and Practice among Women of Over 40 Years in Iran

Objective: This paper aims to report the relationship between perceptions of mammography and screening practices. Methods: This cross-sectional study was conducted between May and September 2017, involving 400 women of over 40 years old, who was referred to as urban health centers in Tehran, Iran. The subjects were selected by multi-stage cluster sampling. Women with inconsistent mammography perceptions and practices were identified the Pros and Cons of mammography behavior for perceptions and Transtheoretical model (TTM) stage of adoption for prior and intended screening practices. The research instrument included a self-administered questionnaire and data were analyzed using descriptive statistics and measures of central tendency, and the chi-square, T-tests, and correlation regression analysis. Results: The average age participant was 45.6±5.4. Consistent with the TTM and pros and cons of mammography, women in action tended to have more positive perceptions of mammography than women in pre-contemplation or contemplation (mean decisional balance: action= 16.8; SD, 1.4; contemplation=1.8; SD, 0.48; precontemplation= SD, 1.4;0.56; p<0.001). Conclusion: results of the current study indicate there are inconsistent mammography perceptions and practice among women in Iran, then we recommend that future intervention, consider setting factors in addition to standard perceptions focused counseling.

Stages of Change for Mammography Among Mexican Women and a Decisional Balance Comparison Across Countries

An analysis of the adoption of secondary preventive behaviors is significant in regions with disparities in mammography use and breast cancer survival. Therefore, we determined the cognitive factors and the degree to which they differentiate stages of change in mammography among Mexican women. We also compared the decisional balance performance at Mexico, Switzerland, South Korea, and the USA. A cross-sectional study was designed for women in the stages of precontemplation (n = 240), contemplation (n = 243), action (n = 205), maintenance (n = 311), and relapse (n = 348). We only considered those ≥40 years with no cancer history. We measured the pros, cons, and self-efficacy, among other components. The decisional balance was estimated, and the result was transformed into T-scores. Odds ratios (OR) and 95% confidence intervals (CI) were estimated with multinomial logistic regression using precontemplation as the reference group. The decisional balance distinguished stages partially: in contemplation, the OR was 1.26 (95%CI 1.08, 1.47) and in maintenance, 1.34 (95%CI 1.13, 1.59); in action and relapse, the statistical significance was marginal (p < 0.10). The decisional balance T-score performance registered variations among countries. Additionally, the effect of self-efficacy progressively ascended from contemplation to action and maintenance (OR = 1.29 [95%CI 1.05, 1.58], 1.53 [95%CI 1.20, 1.96], and 2.48 [95%CI 1.82, 3.39], respectively). Furthermore, risk perception and severity did not have an effect on stages of change among Mexican women. Recognition of what provokes action in a population is a key factor in the efficacy of screening programs. Variations among countries highlight the necessity for importance of investigating cognitive determinants for mammography in specific areas.

Talib R, Spurrier N. The effectiveness of a stage-based lifestyle modification intervention for obese children

BACKGROUND

Interventions that encompass behavioural modifications of dietary intake and physical activity are essential for the management of obesity in children. This study assessed the effectiveness of a stage-based lifestyle modification intervention for obese children.

METHODS

A total of 50 obese children (7-11 years old) were randomized to the intervention group (IG, n = 25) or the control group (CG, n = 25). Data were collected at baseline, at follow-up (every month) and at six months after the end of the intervention. IG received stage-based lifestyle modification intervention based on the Nutrition Practice Guideline for the Management of Childhood Obesity, while CG received standard treatment. Changes in body composition, physical activity and dietary intake were examined in both the intervention and control groups.

RESULTS

Both groups had significant increases in weight (IG: 1.5 ± 0.5 kg; CG: 3.9 ± 0.6 kg) (p < 0.01) and waist circumference (IG: 0.1 ± 0.5 cm; CG: 2.2 ± 0.7 cm) (p < 0.05), but the increases were significantly higher in CG than IG. Body Mass Index (BMI)-for-age z scores decreased significantly in IG (- 0.2 ± 0.0, p < 0.01) but not in CG. The physical activity of the IG significantly increased (0.44 ± 0.13) compared with that of CG (- 0.28 ± 0.18), and the difference in mean change between groups was statistically significant (p < 0.05). Dietary intake was not significantly different between the two groups. However, calorie and carbohydrate intake decreased significantly in both groups.

CONCLUSIONS

A stage-based intervention that modified dietary and physical activity behaviour may be effective in weight management for obese children.

Determinants of mammography adoption among iranian women: What are the differences in the cognitive factors by the stages of test adoption?

Our aim in this cross-sectional study was to investigate the predictors of the stages of change in mammography adoption (MA) based on Health Belief Model among Iranian women. Through multistage cluster sampling, we recruited and interviewed 1131 women older than 40. After statistical adjustment for other risk factors, perceived barriers (OR D 0.84, 95% CI D .81-.87) and benefits (OR D 1.17, 95% CI D 1.11-1.24) were significant predictors for MA. Majority of the women were in the pre-contemplation and contemplation stages of change for MA. Our findings are informative for the development of targeted interventions to foster MA among women.

Predicting the stages of adoption of cervical cancer screening among Korean women

OBJECTIVE

We examined the Transtheoretical Model (TTM) of behavioral change based on cervical cancer screening among Korean women. We assessed the stages of Pap smear adoption, positive and negative attitudes toward Pap smear, and contributory factors.

METHOD

This study was based on the 2007 Korean National Cancer Screening Survey, which included a total of 1224 women > or =30 years. Multiple logistic analyses were conducted to determine the factors that influenced the women's stages of adoption.

RESULTS

Fifty-seven percent of the women reported on-schedule screening while 43% did not. Those subjects who were 50-64 years old, had higher incomes, married, lived in a rural area, exercised regularly, and had regular checkups were more likely to be in maintenance than in precontemplation. However, the con scores were negatively associated with a transition from precontemplation to maintenance. Further, a high con score was associated with being in relapse risk or relapse rather than in maintenance while the pro scores were not significant across the stages of adoption.

CONCLUSION

Our results confirm the applicability of the TTM to Pap smear screening in an Asian context. Age, income, marital status, residency, regular exercise, health checkups, and con scores were significantly associated with the stage of adoption.

Socio-demographic determinants of participation in mammography screening

Our objective was to use individual data on socio-demographic characteristics to identify predictors of participation in mammography screening and control to what extent they can explain the regional difference. We used data from mammography screening programmes in Copenhagen, 1991-1999, and Funen, 1993-2001, Denmark. Target groups were identified from the Population Register, screening data came from the health authority, and socio-demographic data from Statistics Denmark. Included were women eligible for at least 3 screens. The crude RR of never use versus always use was 3.21 (95%CI, 3.07-3.35) for Copenhagen versus Funen, and the adjusted RR was 2.55 (95%CI, 2.43-2.67). The adjusted RR for never use among women without contact to a primary care physician was 2.50 (95% CI, 2.31-2.71) and 2.89 (95% CI, 2.66-3.14), and for women without dental care 2.94 (95% CI, 2.77-3.12) and 2.88 (95% CI, 2.68-3.10) for Copenhagen and Funen, respectively. Other important predictive factors for nonparticipation were not being married and not being Danish. In conclusion, to enhance participation in mammography screening programmes special attention needs to be given to women not using other primary health care services. All women in Copenhagen, irrespective of their socio-demographic characteristics, had low participation. Screening programmes have to find ways to handle this urbanity factor.
