Factors associated with the uptake of cervical cancer screening among women in portland, Jamaica.

BACKGROUND: Cervical cancer is the second most common cancer among women worldwide and is the leading cause of deaths in developing countries. Despite the strong evidence that cervical cancer screening results in decreased mortality from this disease, the uptake for cervical screening among Jamaican women remains low. AIMS: This study was carried out to identify factors associated with Jamaican women's decisions to screen for cervical cancer. MATERIALS AND METHODS: Cross-sectional descriptive study of 403 women aged 19 years and older from Portland, Jamaica. An interviewer-administered questionnaire assessed the women's cervical cancer screening history, as well as their knowledge, attitudes, and practices regarding the disease and screening. RESULTS: Of the 403 women interviewed, 66% had a Papanicolaou (Pap) smear and only 16% had a Pap test within the past year. Significant predicators of uptake of screening were being married, age, parity, discussing cancer with health provider, perception of consequences of not having a Pap smear, and knowing a person with cervical cancer. Women who did not know where to go for a Pap smear were 85% less likely to have been screened (prevalence odds ratio (POR): 0.15, 95% confidence interval (CI): 0.04, 0.52). CONCLUSIONS: This study showed suboptimal uptake of cervical cancer screening among Jamaican women. Multipronged approaches are needed to address barriers to screening, as well as identify and support conditions that encourage women's use of reproductive health services, thereby reducing incidence and mortality rates from cervical cancer.

High speed nano-metrology.

For manufacturing at the nanometre scale a method for rapid and accurate measurement of the resultant functional devices is required. Although atomic force microscopy (AFM) has the requisite spatial resolution, it is severely limited in scan speed, the resolution and repeatability of vertical and lateral measurements being degraded when speed is increased. Here we present a new approach to AFM that makes a direct and feedback-independent measurement of surface height using a laser interferometer focused onto the back of the AFM tip. Combining this direct height measurement with a passive, feedback-free method for maintaining tip-sample contact removes the constraint on scan speed that comes from the bandwidth of the z-feedback loop. Conventional laser reflection detection is used for feedback control, which now plays the role of minimising tip-sample forces, rather than producing the sample topography. Using the system in conjunction with a rapid scanner, true height images are obtained with areas up to (36 × 36) µm(2) at 1 image/second, suitable for in-line applications.

Determinants of adequate follow-up of an abnormal Papanicolaou result among Jamaican women in Portland, Jamaica.

BACKGROUND: Among Jamaican women, cervical cancer is the second leading cause of cancer mortality but factors that facilitate follow-up of women receiving abnormal Pap smear results are not known. We examined whether socio-demographic factors, factors reported by the women, and assistance received for follow-up facilitate adequate follow-up of abnormal Pap smears. METHODS: One hundred and twenty-one women who had abnormal Pap results during June 1998-September 2005 in Portland, Jamaica were interviewed to identify determinants of adequate follow-up. Chi-square, t-test and multivariable logistic regression analysis were used to identify determinants. RESULTS: Only half of the women in this sample sought adequate follow-up. These women had a lower number of surviving children, higher monthly income, and perceived the cost of services to be inexpensive. Advice about the timing of the follow-up activity and the next step to take by the healthcare workers were significant determinants of adequate follow-up. Women who received advice on the timing of follow-up were almost six times (adjusted OR: 5.99, 95% CI: 1.17, 30.66, p<0.05) more likely to seek adequate follow-up after adjusting for other factors. CONCLUSIONS: Perceived low cost of services as well as assistance provided by healthcare workers regarding follow-up action helps to facilitate adequate follow-up of abnormal Pap smear results.
