The Mean

Objectives. To examine masked hypertension persistence over 5 years.Methods. White-collar workers were recruited from three public organizations. Blood pressure (BP) was measured using Spacelabs 90207. Manually operated BP was defined as the mean of the first three readings taken at rest. Ambulatory BP was defined as the mean of the next readings taken every 15 minutes and recorded during working hours. BP was assessed three times over 5 years. Masked hypertension was defined as manually operated BP less than 140 and less than 90 mmHg and ambulatory BP at least 135 or at least 85 mmHg. Sustained hypertension was defined as manually operated BP at least 140 or at least 90 mmHg and ambulatory BP at least 135 or at least 85 mmHg or being treated for hypertension.Results. BP measurements were obtained from 1669 participants from whom 232 had masked hypertension at baseline. Persistence of masked hypertension was 38% and 18.5%, after 3 and 5 years, respectively. Progression to sustained hypertension was 26% and 37%, after 3 and 5 years, respectively.Conclusion. Among baseline masked hypertensives, one-third progressed to sustained hypertension and about one out of five remained masked after 5 years, potentially delaying diagnosis and treatment.

The Mean

Previous studies on the effect of long working hours on blood pressure have shown inconsistent results. Mixed findings could be attributable to limitations related to blood pressure measurement and the lack of consideration of masked hypertension. The objective was to determine whether individuals who work long hours have a higher prevalence of masked and sustained hypertension. Data were collected at 3-time points over 5 years from 3547 white-collar workers. Long working hours were self-reported, and blood pressure was measured using Spacelabs 90207. Workplace clinic blood pressure was defined as the mean of the first 3readings taken at rest at the workplace. Ambulatory blood pressure was defined as the mean of the next readings recorded every 15 minutes during daytime working hours. Masked hypertension was defined as clinic blood pressure < 140/90 mm Hg and ambulatory blood pressure ≥135/85 mm Hg. Sustained hypertension was defined as clinic blood pressure ≥140/90 mm Hg and ambulatory blood pressure ≥135/85 mm Hg or being treated hypertension. Long working hours were associated with the prevalence of masked hypertension (prevalence ratio 49+ =1.70 [95% CI, 1.09–2.64]), after adjustment for sociodemographics, lifestyle-related risk factors, diabetes mellitus, family history of cardiovascular disease, and job strain. The association with sustained hypertension was of a comparable magnitude (prevalence ratio 49+ =1.66 [95% CI, 1.15–2.50]). Results suggest that long working hours are an independent risk factor for masked and sustained hypertension. Workplace strategies targeting long working hours could be effective in reducing the clinical and public health burden of hypertension.

Abstract BACKGROUND Masked hypertension (nonhypertensive in the clinic setting but hypertensive outside the clinic during wakefulness) is characterized by increased blood pressure in response to physical and emotional stressors that activate the sympathetic nervous system (SNS). However, no studies have assessed vascular reactivity to a pharmacological SNS challenge in individuals with masked hypertension. METHODS We analyzed data from 161 adults aged 25 to 45 years (mean ± standard deviation age 33 ± 6 years; 48% were African American and 43% were female). Participants completed ambulatory blood pressure monitoring, and a standardized α 1-adrenergic agonist phenylephrine test that determines the dose of phenylephrine required to increase a participant’s mean arterial pressure by 25 mm Hg (PD25). RESULTS Twenty-one participants were considered to have masked hypertension (clinic systolic blood pressure (SBP) &lt;140 and diastolic blood pressure (DBP) &lt;90 mm Hg but awake SBP ≥135 or DBP ≥85 mm Hg), 28 had sustained hypertension (clinic SBP ≥140 or DBP ≥90 mm Hg and awake SBP ≥135 or DBP ≥85 mm Hg), and 106 had sustained normotension (clinic SBP &lt;140 and DBP &lt;90 mm Hg and awake SBP &lt;135 and DBP &lt;85 mm Hg). After multivariable adjustment, the mean (±SE) PD25 was less in participants with masked hypertension compared with their counterparts with sustained normotension (222.1 ± 33.2 vs. 328.7 ± 15.0; P = 0.012), but similar to that observed in subjects with sustained hypertension (254.8 ± 31.0; P =0.12). CONCLUSIONS Among young and middle-aged adults, masked hypertension is associated with increased vascular reactivity to a SNS challenge, which may contribute to elevated awake BPs as well as to increased cardiovascular disease risk.

Abstract Objective Working status is identified as a major risk factor of poor breastfeeding practices among workers. This study aimed to evaluate the knowledge, attitude, and factors associated to breastfeeding practice among white-collar and blue-collar workers in Indonesia. Methods A cross-sectional study was performed in two factories and three government offices in Jakarta from December 2012 to February 2013. Subjects were female workers whose children aged 6 months to 24 years old and actively working in the factory and/or office. The factors studied were selected socio-demographic and occupational characteristics, score on knowledge and attitude and breastfeeding practice during working hours. Results From a total of 192 subjects, 73% of white-collar workers had good knowledge on breastfeeding, in contrast with 55% of blue-collar workers who had not good of breastfeeding knowledge (P<0.001). Most of the subjects were conducting breast pumping during working hours, however 15% of white-collar worker and 17% of blue-collar worker were never breastfeed nor breast pumping at work. Working status (P=0.005) and knowledge (P=0.002) were factors associated with breastfeeding practice among workers. Conclusion White-collar workers have a better knowledge, attitude, and practice toward breastfeeding. Knowledge improvement related to breastfeeding benefits and supports to working mothers are key priority, however advocacy to employers, manager, and supervisor in providing breastfeeding facilitations and programs support were also critical to successful breastfeeding practice among workers.
